In a previous blog, I reviewed the magnificent GPO Passion HD 10 x 42, one of the flagship models from the relatively new firm, German Precision Optics. For the money, I felt it was an excellent bargain, especially when compared to significantly more expensive models from Zeiss, Leica and Swarovski. Gone are the days when you have to shell out several grand to get a world class binocular, and in my opinion, GPO are definitely leading the way in this regard.

But having enjoyed the instrument for a couple of weeks, reality began to bite. As I’ve remarked before, the 42mm format is not my favourite. It has nothing to do with optics or ergonomics. It’s about weight. You see, I’ve come to strongly favour smaller formats. I already own and frequently use a world-class pocket binocular, the Leica Ultravid BR 8 x 20, but my experiences with larger binoculars convinced me that an optimum size for me would come from the compact class of binoculars, with apertures in the 30-35mm size class. Such instruments are easier to hold, easier to view through, and have more light gathering power. But I was also on the look out for a 10x instrument, to afford greater reach for my glassing targets, especially birds. While I’ve enjoyed some really high quality 10 x 25 pocket glasses in the past, their smaller objectives let in less light – an important parameter when glassing in shady areas during daylight hours, and especially for discerning subtle colour tones.

Unfortunately, GPO did not offer a smaller model in their flagship HD range, but they did have a 10 x 32 model from their more economical Passion ED line. After doing some research on this model(see the Preamble link above), I decided to pull the trigger and ordered one up for testing; enter the GPO Passion ED 10 x 32.

The GPO Passion ED 10 x 32 and its high quality carry case.

First Impressions

Costing less than half the price of the larger 10 x 42 HD model, the GPO Passion ED 10 x 32 package arrived with all of the same great quality accessories that delighted me in the larger HD binocular: I received the same neck strap, a smaller clamshell case, snugly fitting rain guard and objective lens covers, GPO-branded microfibre lens cleaning cloth, instruction manual and warranty card. It arrived in the same high quality presentation box as the larger HD model, with its unique serial number etched into the underside of the binocular and on the outside of the box. Very neat!

The GPO Passion ED 10x 32 has the same excellent build quality as the larger HD models.

Picking up the binocular and holding it, I was chuffed to see how well it fitted my hands. The narrow, single bridge allowed me to wrap my fingers round the barrels better than any other 30-32mm model I’ve previously handled. And while the instrument has a lovely, solid feel about it, with its sturdy magnesium alloy chassis, I was very reassured by its considerably lower weight; just 500g as opposed to ~ 850g for the larger, HD instrument.

The GPO Passion ED 10 x 32 fits perfectly in my hands!

The central hinge is nice and stiff, making it difficult to change the IPD on the fly. I like that. The binocular has a rather oversized central focus wheel, just like the heavier HD model, and I was relieved to see that it moved very easily and smoothly, with just one finger. The professionally machined aluminium eyecups are, in my opinion, even more impressive on the Passion ED model than the HD, rigidly locking into place with one intermediate click stop. The immaculately applied rubber armouring has two textures, just like the HD, a roughly textured side armouring and a silky smooth substrate covering the inside of the barrels.

All in all, very impressive!

Ergonomics

The GPO Passion ED shares many of the high quality ergonomic features built into the more expensive HD models. The ocular and objective antireflection coatings are immaculately applied and have a fetching magenta hue when observed in broad daylight. Unlike the HD models however, they do not have the hydrophobic coatings – an acceptable sacrifice, and then some.

Ocular lens end of the GPO Passion ED 10 x 32.

The objective lenses are recessed to an extent I’ve not seen before on any other compact model I’ve had the pleasure of using. I measured it at about 9mm! Why so deep? Well, it could be to protect those objectives from the vagaries of the weather; rain, wind, and stray light etc, or maybe partially compensating for the lack of hydrophobic coatings on the glass? Whatever the precise reason, I liked it!

The beautiful magenta coloured antireflection coatings on the Passion ED are immaculately applied, and note the exceptionally deeply recessed objective lenses!

The eyecups are beautifully designed; absolutely world class! They extend upwards with one intermediate position between fully retracted and fully extended, and lock into place rigidly with a reassuring ‘click.’ This is one binocular you can safely store inside its case with the eyecups fully extended for quicker deployment. They ain’t gonna budge!

Eye relief proved perfect for me, as I don’t use eye glasses, but I think the stated value of 15mm might be a bit optimistic, as I was not easily able to observe the full field of view keeping the eyecups down and wearing my varifocals.

The beautifully machined aluminium eyecups are world class, clicking into place with absolute rigidity.

Unlike the more expensive HD models which have a centre-locking dioptre adjustment, the Passion ED presents a more cost-effective solution by returning it to under the right ocular lens. While adjusting it, I noted its excellent rigidity, rendering it very resistant to accidentally moving while in the field. I felt it was a very acceptable compromise. Furthermore, the + and – settings are clearly marked, and so it’s very easy to memorise its optimal positioning should the instrument be used by others.

The oversized focus wheel is very easy to access and manoeuvre using one finger. It has a very grippy, texturized rubber overcoat, identical in fact to the more expensive HD models. Taking just over one complete turn to go from one extreme of its travel to the other, I would rate its speed as very fast; a good thing in my opinion, as it will be used primarily for birding, where big changes in focus position are often required following a mobile avian target. Motions are very smooth though, but I did notice a very small bit of play with it; similar in fact to focus wheel on the Leica Trinovid HD 8 x 32 I used and enjoyed a while back. Here the HD model came out better in my opinion, as I was unable to detect any play whatsoever with the 10 x 42.

I was most highly impressed with the way the binocular felt in my hands though. In truth, I don’t recall enjoying wrapping my medium sized hands around the barrels as much as on any other compact binocular I’ve tested. I reckon that this is attributed to the narrow bridge, which exposes those long, slender barrels. It’s simply a joy to hold, perfectly stable and always a thrill to bring to my eyes!

All in all, the build quality and handling of the Passion ED 10 x 32 are absolutely unrivalled in this moderate price class. GPO has clearly gone well beyond the call of duty in the design and execution of these new, highly-advanced compact binoculars!

Optics

The GPO Passion ED 10 x 32 came perfectly collimated. I was able to ascertain this by carefully focusing the binocular on the bright star Capella and then moving the right eye dioptre to the end of its natural travel. The perfectly focused star from the left barrel was found right in the centre of the defocused star diffraction pattern.

The lady reviewing the 10 x 32 in the Preamble to this review stated that the binocular had no issues with internal reflections and stray light and I was able to affirm this in the 10 x 32 I received. The image of an intensely bright beam of light from my IPhone torch was clean and devoid of diffraction spikes.

The exit pupils are nice and round and have little in the way of light leaks immediately around the pupil; a very good result but not quite in the same league as those found on the more expensive Passion HD 10 x 42.

Left eye pupil.

Right eye pupil.

In broad daylight, the images served up by the GPO Passion ED are very impressive! It is bright and very sharp across the entire field, with very little in the way of distortion even at the field stops. Like the Passion HD model, it enjoys a very decisive snap to focus on whatever target I turn it on. The small exit pupil ensures that the best part of your eye does all the imaging. Colours are vivid and natural but to my eye it has a slightly warm tone, with greens and browns coming through very strongly. Contrast is very good but not quite in the same class as the GPO Passion HD 10x 42 I tested it against. Glare suppression was also impressive. Comparing it to my control binocular – a Barr & Stroud Series 5 8x 42 ED – which exhibits excellent control of all types of glare, including veiling glare, the little Passion ED proved to be slightly superior to it. However, it was not quite as good in this capacity as the GPO 10 x 42 HD model, which exhibits the best control of glare that I have personally witnessed in any binocular.

Close focus is considerably better than I had expected. The accompanying user manual claimed 2.5m for this model, but I measured it at only 1.92m!

Colour correction in the GPO Passion ED 10 x 32 is very impressive! Pointing the binocular into the branches of a leafless tree against a bright overcast sky, the centre of the image is completely devoid of it, and even off axis, I could only coax the merest trace and only near the field stops. Returning to testing the binocular under the stars, I was able to verify just how well corrected the field of view is. Stars remain nice pinpoints nearly all the way to the edges. I attribute this excellent result to GPO’s optical engineers’ choice of field size. 6 degrees is not large by modern standards so it’s easier to achieve optical excellence using standard eyepiece designs. More on this a little later.

Venturing out on a freezing, misty December night to observe the full Moon, the GPO Passion ED 10 x 32 threw up a beautiful image. It was clean and sharp and contrasty. Secondary spectrum was non existent over the vast majority of the field, with only the extreme edges showing some weak lateral colour. Field illumination was also excellent, as with the 10 x 42 HD, with very little in the way of brightness drop off as the bright silvery orb was moved from the centre to the edge of the field. I also judged field distortion to be excellent in these tests too. The Moon remains razor sharp across most of the field, and only shows slight defocus at the field stops. Indeed, it was very comparable to the results I got with my optically excellent Leica Ultravid 8 x 20 in this regard.

Complementary instruments.

These are excellent results, and quite in keeping with the comments made by the lady from Optics Trade, as revealed in the Preamble video linked to at the beginning of the review. Indeed, these results place the GPO Passion ED in the top tier optically. Its colour correction was notably better than the Leica Trinovid HD 8 x 32, and I felt its sharpness and contrast were perhaps a shade better too. I’m confident that this 10 x 32 ED could hold its own against top-rated compact binoculars up to twice its retail value or more.

Notes from the Field & Concluding Comments

The view through the GPO Passion ED 10 x 32 is very stable and immersive. On paper a field of view of 105m@1000m might seem restrictive but in practice you never get that impression. There are no blackouts, rolling ball effects or any other issues common to compact models sporting wider fields of view with field flatteners. This makes panning observations particularly pleasurable with this instrument. To be honest, I suspected that this would have been the case after I had put the Passion HD 10 x 42 through its paces. Indeed I would hazard a guess that both binocular lines – the HD and ED – have substantially similar optical designs. As an experienced glasser, I have no abiding interest in very large fields of view. Indeed, I tend to think of those wide angle binoculars as rather distracting and more suited to beginners than more seasoned observers. I’m interested in vignettes not vistas.

Goldilocks Binocular.

So there you have it! The GPO Passion ED 10 x 32 is, for me, a Goldilocks binocular, serving my purposes perfectly and fitting my hands like a tailor-made glove. It pays to mention that GPO also market a 8 x 32 with a wider field of view, and two 42mm models with powers of 8x and 10x; so something for everyone! Check them out as soon as you can. You’ll not be disappointed!

 

Dr Neil English has some exciting news to reveal early in the new year. For now, he’d like to wish all his readers a Very Happy Christmas!

In several previous reviews, I’ve showcased a few binoculars made by Barr & Stroud. As I explained before, I cut my first binocular teeth with a modern roof prism binocular by Barr & Stroud just over three years ago, and have always been impressed by their excellent bang for buck. Unlike so many other instruments in the same price range, which showed mis-collimated barrels, too much field curvature, chromatic aberration and sub-standard ergonomics, Barr & Stroud products punched well above their weight in terms both of the quality of the optics they presented and the rugged no-nonsense chassis in which those optics were housed. In this review, I’ll be discussing the optical and ergonomic features of two nifty monoculars from the same company; the Sprite Midi 8 x 42, and the higher power Sprite Plus 15 x 50. But before we get to those details, let’s take some time to go over the reasons why a monocular might suit an individual more than a binocular.

A monocular is, quite simply, half a binocular. Thus, it uses one eye rather than two. Some people have natural deficiencies in one eye, such as severe astigmatism for example, that results in their inability to properly adjust the dioptre setting on a regular binocular leading to a blurred image. Others have one eye damaged in some way and so can’t avail of the natural advantages of using both eyes. Some folk like to use monoculars because they are smaller and lighter than the equivalent binocular and this may prove to be very important if space and weight constraints are very tight. Monoculars are now available in many sizes and magnifications. Low power monoculars have magnification ranges similar to that found in modern compact and full-sized binoculars, but higher powered units function more like mini-spotting scopes, enabling the user to lock in on small targets beyond the range of binoculars or seeing details quite invisible to conventional, hand-held binoculars. Yet another advantage of a monocular is cost; it’s just cheaper to use a monocular than a binocular of the same aperture.

What does one lose in going from a binocular to a monocular? Well, a few things actually. Depth perception for one thing, as our eyes were designed in such a way that they both create the sensation of focus depth, allowing us to gain a sense of the 3-dimensional shape of objects and how far away they are. Many observers enjoy up to a 40 per cent gain in contrast using binoculars compared with the same sized monocular. The reasons for this are not entirely understood but suffice it to say that using two eyes increases the signal to noise  ratio in the electrical impulses that are created in viewing an object. Many observers also report that monoculars are harder to hold steady than binoculars of the same aperture. Despite these drawbacks, most of the main binocular manufacturers also produce monoculars, and Barr & Stroud is no exception.

                                First Impressions & Ergonomics

Both the Barr & Stroud monoculars have a polycarbonate chassis overlaid by a grippy, green rubber armouring. The polycarbonate body cuts down on weight and is perfectly adequate for most observing schedules. Both instruments fit very easily in the palm of your hand. They are both very lightweight; the 8 x 42mm weighing at 350g and the 15 x 50mm just 100g more. In this capacity, both the Sprite Midi 8x 42 and Plus are no heavier than the average compact binocular. Both instruments come with a rubberised rain guard and a tethered objective cover, which means you’ll never lose it in the field.

Both Barr & Stroud Monoculars have a permanently tethered objective cover.

In a previous blog, I commented on my great fondness for the quality of the focusers on a number of Barr & Stroud binoculars. And these binoculars are no exception. Both instruments have silky smooth focus wheels, which are large and easy to negotiate with just one finger.  They do however have slightly different textures; I found that I preferred the less expensive Midi Sprite focus wheel over the larger 15 x 50 Sprite Plus. It was just slightly easier to grip and engage with throughout its travel.

The focus wheel on both Barr & Stroud monoculars are of high quality but I liked the extra grip afforded by the less expensive Midi model.

Both monoculars are equipped with pull-up eyecups that lock rigidly in place. The smaller 8 x 42 Sprite Midi has very generous eye relief. I was easily able to observe the full field with my eye glasses on. The larger Sprite Plus however, has considerably less eye relief, but if push came to shove, I was just able to engage with the full field but it was certainly challenging!

Both monoculars have well made twist up eyecups that lock rigidly in place.

Both Barr & Stroud monoculars come with a screw thread which enables you to mate it to a tripod or monopod for extra visual stability.

Both monoculars can be easily mated to a tripod or monopod.

Both monoculars come with a padded case and a carry strap that you can easily affix to the instrument.

Each monocular is supplied with a padded carry case and strap to carry it from place to place.

Optics

Both Barr & Stroud monoculars feature fully multicoated optics and BaK4 Schmidt Pechan roof prisms. The less expansive Sprite Midi 8x 42 is not phase coated however, unlike the higher power 15 x 50 Sprite Plus. The Sprite Midi 8 x 42 appears to have the same specifications as the 8 x 42 Sahara binocular with a field of view of 129m@1000m or 7.35 angular degrees but has a noticeably longer close focus at 2.59m(as opposed to just 1.98m for the Sahara binocular). Intriguingly, the Sprite Plus 15 x 50 monocular has a significantly better close focus of just 2.2 metres, which is also considerably less than the 2.5m advertised.

The higher power Spite Plus 15 x 50 has phase coated roof prisms unlike the smaller Sprite Midi.

Looking at the exit pupil of both monoculars showed a significantly better result for the larger Sprite Plus 15 x 50. Although both presented with nice round pupils, the 8 x 42 Midi had more stray light close to the pupil, as the images below show.

The exit pupil presented in the Sprite Midi 8 x 42.

The exit pupil presented by the Sprite Plus 15 x 50.

These results were also somewhat reproduced in my tests for internal reflections, by directing a bright beam of my IPhone 7 torch into the monoculars from across a room and inspecting the images visually. The Midi 8 x 42 did show significantly more internal reflections and diffused light around the beam than the larger 15 x 50 Plus unit. That said, these stray light artefacts were not terribly injurious to the image and both gave passable results when directed at a sodium street light after dark, and also on a bright Moon.

The daylight images served up by the 8 x 42 Midi monocular are bright and sharp. Contrast is good and chromatic aberration is very well controlled, with only the outer part of the field showing a trace. The 8 x 42 has a large sweet spot covering perhaps 60 per cent of the field but beyond that astigmatism and pincushion distortion increase gradually towards the field stop. I was also able to confirm these findings under the stars.

I judged the larger Sprite Plus 15 x 50 to be better optically than the smaller 8 x 42. Despite its higher power, the images it served up had higher contrast than the latter, a consequence I suppose of its phase corrected roof prisms. The field of view was flatter and better corrected in the 15 x 50 too. Star testing showed that most of its 3.78 degree true field was very well corrected, with only the outer 15 per cent showing significant distortion. Chromatic aberration was more conspicuous but never to an unacceptable degree. High contrast objects against a bright over cast sky background does show some but that’s just par for the course and most folk can easily ignore it and just get on with observing.

I found the 15 x 50 unit more versatile than the 8 x 42. With its substantial magnification, I enjoyed employing it as a mini spotting scope, either mounted on a monopod or simply by finding a suitable branch or fence post to rest it on. If you’re observing from a car, a small beanbag also works wonders stabilising the view. The 15x is just right for bridging the gap between a standard binocular view and a larger spotting scope. For example, I was able to make out nice, high-resolution details on a Grey Heron that were quite invisible in 8x and 10x binoculars. The 15 x 50 is a nifty instrument for studying the phases of the Moon; all the way from slender crescent to full on full Moon. Crater fields and maria show up sharply and in very high contrast; a true refractor image. The Plus proved to be a rather good, low-power, rich field telescope too, delivering up very impressive views of larger deep sky objects such as the Pleiades, the Beehive Cluster, the Andromeda Galaxy and the Double Cluster.  Views of the Sword Handle of Orion also proved very compelling through the Spite Plus.

In addition to its higher magnification, the better close focus on the Sprite Plus 15 x 50 made it a rather good, long distance microscope, affording crystal clear views of leaf litter, bark, rock formations, fungi and tree branches. Indeed, if coupled to a digi-scoping adapter, it works well as an ultraportable telephoto lens.

In summary, both the Sprite Midi 8 x 42 and Plus 15 x 50 represent excellent value for money. They are well made, small, lightweight, easy to use, weather resistant and serve up very decent optics for their modest price tags.  If your outdoor activities are in need of a magnification boost, give one of these monoculars a try. You won’t be left second guessing!

Svbony is a relatively new Hong Kong-based optics firm that began supplying amateur astronomers and nature enthusiasts with a wide range of cost-effective but good quality instruments and accessories in 2014. A google search of Svbony products will reveal a large and international fan base of customers who have been pleased with their eyepieces, filters, night vision devices and more recently, the company’s extensive range of astronomical and terrestrial spotting scopes.

My introduction to Svbony came as a result of testing out a trio of high-performance binoculars from their SV 202 range. You can see those reviews here, here and here. What astonished me most about these binoculars was their excellent optical and mechanical performance at prices that were simply unbeatable in today’s market. These experiences collectively whetted my appetite to explore some more of their products, and in this review I will be sharing my thoughts on their newly launched mini-spotting scope that combines weatherproof ruggedness with good optical performance, in an ultra-portable package; enter the SV 410 9-27 x 56mm ED spotter, which first appeared on the market back in April of this year.

The scope was purchased from Amazon UK for a price of £179.99, and arrived a couple of days after ordering. Readers may also purchase the instrument directly from Svbony via this link, which will allow you to purchase the scope more cheaply if you can tolerate a longer shipping time(usually about 8 days)The instrument came well packed inside a long, white box with the blue and yellow Svbony logo, and with all of its accessories neatly packed inside. The little spotting scope was carefully placed inside a snugly fitting black foam bed, carefully cut to match the angled shape of the instrument. The accessories included a comprehensive multi-language instruction manual, a lens cleaning cloth, a nicely machined protective jacket and carry strap. The scope itself came with good quality and tightly-fitting rubber ocular and objective covers.

The Svbony mini spotting scope is very small and easy to carry, almost fitting inside a large pocket.

Ergonomics

Right from the get go, I was very impressed with the build quality of the SV 410 mini spotter. It feels very solid in the hand but only weighs about the same as a typical 8 x 32 binocular. The metal chassis (possibly a magnesium alloy or aluminium) is overlaid by a mild green rubber armouring. The helical focuser, located between the objective and the eyepiece moves nicely with a good deal of friction. There is no facility for fine focusing like on larger spotting scopes, which offer a larger range of magnifications, but in use I found that it was more than adequate to get precise focus since the highest power (27x) is not large enough to necessitate a fine focus knob.

The zoom eyepiece is clearly marked with magnifications from 9x to 27x which you can choose simply by rotating the eyepiece to dial in your preferred power boost.

The silky smooth zoom function on the eyepiece gives the user a range of magnifications from 9x through 27x.

The nicely machined aluminium eyecup is overlaid with soft, black rubber and twists upward to provide the necessary eye relief for non-eye glass wearers. It clicks into place- and you can hear it!– without any play, and holds its position very well. Another good design feature of the eyecup is its continuous motion from fully retracted to extended -that means you can dial in your preferred eye relief. I found, for example, that the eyecups pushed slightly down renders excellent results without glasses.

The instrument is quoted as having an eye relief of 18mm, but I found it was a little shorter than this. I did however test the scope with the eyecup fully retracted with my eye glasses and I was able to see the entire field with no problems but it was fairly tight!

The objective and ocular lens coatings are different from those applied to their SV 202 binoculars, having a mild, greenish tint in broad daylight;

The anti-reflection lens coatings on the Svbony mini spotter are a subdued green.

Unlike larger spotting scopes, there is no lens hood on the Svbony SV 410 spotter, although the objective is quite deeply recessed. Having a hood would afford greater protection against stray light during use in bright daylight but if push come to shove, one can easily be made from a cardboard or plastic sheath. I guess Svbony decided against having a lens shade to keep the weight down to an absolute minimum.

The underside of the mini spotter has a brass screw socket to enable the user to quickly mate it to a monopod or tripod in field use.

Overall, I was very impressed with the build quality on this nifty little spotting scope from Svbony; so small it fits snugly in the palm of your hand.

I keep the tripod mounting bracket on the underside of the scope for quick release from a tripod or monopod.

Optical Evaluation

My first test looked for stray light and internal reflections when pointed at an extremely bright light source. So on went my IPhone torch set to its brightest setting. After focusing the beam from across a living room, I was able to establish that the unit displayed excellent suppression of internal reflections, but also very little in the way of diffused light and no diffraction spikes. Just like their SV 202 binoculars, this spotting scope was up there with them in terms of controlling bright light sources. I confirmed this after dark by looking at a bright sodium street lamp. All was well, as I expected, with a nice clean image of the lamp with no annoying internal reflections or diffraction spikes. Once again, good job Svbony!

Looking at the exit pupil as the scope was racked through its zoom magnification range showed a nice round light shaft throughout. The images below show the exit pupil at the 9x setting and the 27x setting for reference:

Exit pupil at 27x setting

Taking into the consideration the extremely fast focal ratio of this Porro prism spotting scope ( f/3.4), requiring four objective lens(one of which is an ED element) elements in three groups, I knew going in that the total elimination of chromatic aberration would be a tall order. But I was very pleasantly surprised when, after mounting the scope to a lightweight tripod, I racked it through its full range of magnifications, 9x through 27x, focused on a telephone pole set against a uniformly bright overcast sky. I noted that I could obtain a very sharp focus right up to 27x with only a modest amount of chromatic aberration seen around the edges of wires and the pole itself. Furthermore, any secondary spectrum seen was very sensitive to eye placement. I quickly learned to move my eye around to minimise it while observing my targets. In addition, moving off axis shows some lateral chromatic aberration in this scope.

The image is bright and sharp, with excellent contrast. Autumn colours really showed up beautifully using this small spotting scope from the Far East. The eyepiece is not parfocal however, thus requiring a significant amount of refocusing moving from low to high power  The zoom is continuously variable however, from 9x through 27x

The image remained very sharp right out to the field stop, with only very minor field curvature and pincushion distortion; much less severe than the vast majority of binoculars I’ve tested over the last three years!  I took the liberty of capturing some images through the Svbony mini spotting scope using my IPhone and a digi-scoping adapter.  The reader will bear in mind that these images were captured during the most adverse conditions possible with leaden rainclouds, windy gusts and outbreaks of rain. All the images are entirely unprocessed and were taken directly from my IPhone.

First up, an image of some fence posts at just under 44 yards distant. The reader will note the magnification was set to 27x and shows extremely mild field curvature at the edges of the field.

A wooden fence located at a distance of 43.8 yards, captured during very inclement lighting conditions. Next up, an image of a wooden outhouse roof about 20 yards away, showing the brilliant autumn colours coming though in the spotting scope set at 27x:

In my most severe test conducted, I took a shot of a telephone pole at a distance of 35 yards at 27x, showing some secondary spectrum. The reader will note that the amount seen by the naked eye is much less than the IPhone 7 captures:

Finally, I took a picture of a BlueTit at the birdfeeder in my back garden: 15 yards distance, 27x:

Further Notes from the Field

I measured the close focus on the Svbony SV 410 mini spotting scope to be 2.16m or 7 feet, just a little longer than the advertised 2m. That’s an excellent result, closer, in fact, than a raft of other spotting scopes I’ve looked at. The nearest I got was 2.5m for the Opticron MM4 50 ED, and even the closest product to the Svbony – the Celestron Hummingbird 9-27 x 56 ED – has a close focus of nearly 10 feet! That’s great news for those who would like to use their spotting scopes as long range microscope. It’s quite amazing to be able to look at flowers, fungi, rocks, insects, and a host of other things at very close range at powers up to 27x. That, in my opinion, greatly increases its versatility.

Because it’s so small, the little Svbony spotter can be carried in a wide jacket pocket or a rucksack. Stable handholding is eminently possible at a power of 9x, but at higher powers it does benefit from some sort of makeshift support such as a beanbag. I was able to stabilise the image completely by resting the spotter on the branch of a tree while viewing a pair of Mute Swans at one of my local patches, when I could exploit the entire magnification range of the instrument.

For more hassle free results, it pays to mount the spotter on a monopod, and because these are very lightweight and fold up to very convenient sizes, they can be carried about in a rucksack, with no hassle to the rambler.

This would be a good place to compare and contrast some of the specifications of this Svbony mini ED spotting scope to an outwardly similar instrument – the Celestron Hummingbird 9-27 x 56mm ED. As well as having a significantly closer focus than the Hummingbird, it also sports a wider field of view. The Svbony has a field of view range from 2.1 to 4.5 angular degrees, as compared with the Hummingbird at 1.9 to 4.2  degrees. This makes object acquisition that little bit easier with the Svbony The eye relief is also better on the Svbony mini spotter (18mm as opposed to 15mm). Furthermore, the Svbony is about 30g lighter than the Celestron scope. But perhaps the best news of all is that the Celestron Hummingbird ED mini spotter retails for about £299.99. That’s a 66 per cent mark up in price compared with the Svbony! Is the Hummingbird really any better? I have my doubts!

Notes Gleaned from Looking at the Night Sky

Reviewers who only carry out terrestrial observations during daylight hours are prone to miss some important details about their subject instruments. As a case in point, I use my right eye for astronomical viewing through all my telescopes, and this little Svbony was no exception. At 9x I noticed the mild astigmatism in my own eye was showing up in images of bright stars in the spotting scope’s field of view. But when I cranked up the power to 27x, the astigmatism was noticeably less. Viewing with my glasses on effectively eliminated this astigmatism. Had I confined my viewing to daytime targets, I would be none the wiser to this aberration originating from my own eyes.

Star images remained nice and tight nearly all the way to the field stop at all magnifications, just as the photos above reveal. The instrument clearly has a very flat and well corrected field.

The Svbony SV 410 mini ED spotting scope proved to be an excellent instrument for observing the Moon, which I enjoyed doing over a couple of weeks in October. There are no annoying reflections and diffraction spikes in the images it served up. A great amount of detail was gleaned at 27x; craters, maria, valleys and mountains all showed up with beautiful sharpness and contrast. I detected some slight fringing at the lunar limb, but this was also sensitive to eye placement. In comparison to my 20 x 60 Pentax PCF binocular, the Svbony showed slightly less colour fringing on the Moon but was its equal for sharpness and contrast – a very good result indeed, as I rate the latter very highly as a Moon-gazing binocular.

Bright stars like Vega reveal a trace of secondary spectrum at the highest powers as does the bright planet Jupiter, but I was just able to make out two bands straddling the planet’s equator and the four large Galilean satellites were very clearly discerned as tiny stellar-like point sources. I was also delighted to see Saturn’s majestic rings with the little Svbony spotter, and even its largest satellite, Titan.

In the late evening of October 30, I enjoyed a long clear spell with the waning Moon out of the sky. Mounting the spotter on my tripod, I examined a suite of double stars to test the resolving capabilities of this pint-sized scope. My first target was Mizar & Alcor low in the northern sky, where I was able to prize apart the tight companion to Mizar at 27x. Albireo( Beta Cygni) was beautiful and easy at powers above 12x, but most compelling at 27x. The view of the celebrated binocular multiple star system Omicron^1 Cygni was gorgeously presented at 27x, the wonderful colour contrast of its components coming through clearly. The components of Beta Lyrae were also cleanly resolved, and an especially lovely sight at 27x. Perhaps my most challenging split came when I turned the instrument on the orange star Gamma Delphini, now sinking into the west south-westerly sky. Taking that little bit extra care focusing this system at 27x revealed the prize I had been looking for; its fifth magnitude companion being just resolved with a steady gaze. This will make an excellent instrument for observing traditional binocular doubles, allowing you to study them at significantly higher powers than regular binoculars!

The main body of the Pleaides was nicely framed in the 2.1 degree true field of the Svbony SV 410 ED spotting scope at 27x. Many dozens of stars filled the field from edge to edge, including many double and multiple star systems easily discerned at the highest powers available to me. What appeared very odd to me at first, was the orientation of the stars making up this most celebrated herald of autumn. Of course, it presents the view as the eye sees it(only magnified), but being very accustomed to viewing stars through Newtonians and (in a former life), small refractors yielding upright but mirror-reversed images, it took a bit of getting used to in this quirky little spotting scope. Pointing the scope much higher up in the night sky showed me a very nice view of the great Galaxy in Andromeda(M31), together with its fainter companions M32 near the core, and M110 about a degree off to the northwest of the core of M31. The Double Cluster in Perseus, now near the zenith, stood out beautifully at 23x against a jet black hinterland. The Coathanger asterism in Vulpecula was an awesome sight at powers between 15x and 23x. And while sinking quite low into the north-western sky, I enjoyed some very fine views of M13 and M92 in Hercules.

As local midnight approached, I began observing the trio of Messier open clusters in Auriga. At 27x, one can begin to resolve these celebrated clusters into dozens of individual stars.  Later on again, in the wee small hours of Sunday morning, October 31, I went in search of M35, that wonderful, sprawling open cluster in the northern foot of Gemini, and was rewarded by a very compelling sight at powers above 20x, when several dozen of its brightest luminaries began to be resolved in the spotting scope. That weekend night vigil convinced me that a great deal of astronomy can be done with such a tiny scope as this. It’s very easy to find objects at 9x before zooming in for a closer look.

Conclusions & Recommendations

My experiences with the Svbony SV 410 9-27 x 56 ED spotting scope have been very pleasing indeed. Its low cost, solid optical performance, ease of handling, outdoor ruggedness and very light weight will appeal to a great many individuals wanting to make a move into the high magnification world of sport optics. And while not a full-sized instrument with its larger aperture and magnification range, this pint-sized scope will fill a niche for many, serving multiple purposes as a rich field travel and spotting telescope, as well as a high-powered long range microscope that you can take with you anywhere.

Highly recommended!

Investigating the Potential of a Modified Newtonian Reflector as a Spotting Scope.

Plotina: the author’s modified 130mm f/5 Newtonian reflector, with a Vixen Erecting Adaptor and two simple Plossl eyepieces used in the investigation.

A Work Commenced October 3 2021

 

In this blog, I’ll be demonstrating the potential of a small Newtonian reflector operating in spotting ‘scope mode. This follows on from a previous blog I conducted to find a suitable optical device that would give fully erected and correct left-right orientation, just like a conventional spotting scope.

First, a few words of introduction about the telescope. It’s a 130mm f/5 SkyWatcher Newtonian reflector, so has a focal length of 650mm. Because of its open-tube design, the instrument is surprisingly light; just 3.8 kilos(8.4 pounds) and 4.1 kg (9 pounds) with the mounting bracket attached. It acclimates fully in 30-40 minutes, even when taken from a warm indoors environment to the cold of a Winter’s day. But such thorough cooling is only necessary to coax the highest powers out of the instrument.

The instrument has mirrors treated with state-of-the-art Hilux coatings(applied by Orion Optics, UK), increasing its overall reflectivity to 97 per cent. The primary mirror is the original one supplied by SkyWatcher, while the secondary flat mirror was upgraded with an Orion Optics UK secondary, having a flatter surface and smaller semi-major diameter of 35mm. This provides a small 26.9 per cent central obstruction. This size of central obstruction is significantly smaller than a Maksutov or Schmidt Cassegrain (SCT) of the same aperture. Unlike the popular Maksutov, the 130mm Newtonian(aka Plotina), can deliver a significantly lower magnification. For example, using a 32mm Skywatcher Plossl, it delivers a power of just 20x and using another Plossl of focal length 10mm, the telescope provides an amplification of 65x. I used these two eyepieces to demonstrate the spotting scope potential of the Newtonian, as many conventional spotters provide magnifications in this range(20-65x), corresponding to exit pupils of 4.7 and 2mm, respectively.

The contrast transfer is provided by subtracting the aperture of the secondary from the primary(130-35 = 95mm), thus one can expect a degree of contrast equivalent to a 95mm apochromatic refractor. Its light gathering power and resolution(0.89″) are significantly higher than a 95mm refractor, however. This has been borne out in several years of observations of lunar, planetary, double star and deep sky observing. The reader will find several other blogs I have published on this instrument in the past by clicking on the ‘Telescopes’ link on the home page.

The Erecting Adapter: Purchased for £80, the Vixen erecting adapter is a rather long appendage but delivers an upright image with the correct left-right orientation, just like a conventional spotting ‘scope. The lenses in the adapter are fully multi-coated and truncates the field a little when employing longer focal length eyepieces. You simply insert the desired eyepiece into the adapter, focus the ‘scope, and you’re off to the races!

Plotina, with the erecting adapter attached.

The instrument was used in broad daylight outside on a cool, breezy autumnal day, between heavy rain showers. It was mounted on a simple non motorised alt-azimuth(Vixen Porta II). The instrument is equipped with Bob’s Knobs screws for quick and easy collimation using a Hotech laser collimator. Alignment of the optics takes just a few seconds to get precise alignment of the secondary and primary mirrors. All of the images were taken simply by pointing my Iphone 7 into the eyepiece and taking single images. The pictures presented here are the highest resolution I can load onto this website( ~200-750KB), so are not the highest quality that I can potentially show. All the images are completely unmodified, apart from cropping. All distances quoted were measured with a laser range finder, and all the images were taken on the same breezy afternoon of October 3 2021.

Results:

Image 1: Shows a TV satellite dish at a power of 20x located at distance of 27 yards:

Image 2 shows some autumn leaves at 20x and located at a distance of 18.9 yards

Image 3 shows the branches of a tree at 20x located 43.1 yards from the scope:

 

 

Image 4 shows a hill top located at about 2 km distance at 65x

 

 

 

 

 

Discussion:

I am very encouraged by the results I obtained this afternoon. Irrespective of the scepticism of arm chair theorists, the images speak for themselves! The instrument provides very nice, high contrast and colour pure renditions of a variety of targets. Chromatic aberration is particularly well controlled, as expected, given that the Newtonian is a truly apochromatic optical system, though some secondary spectrum is introduced by the eyepieces chosen. In addition, higher quality eyepieces will give better off-axis performance, and because those oculars are inter-changeable, a greater range of  magnifications can be explored. Visually, the images are considerably better when examined with the naked eye. The reader will note that these magnifications are somewhat pedestrian for such a large telescope. Visually, much higher magnifications can be utilised profitably. And although the formidable resolving power of the instrument is clearly in evidence, the images could be improved further by employing a higher quality phone camera. What’s more, the images could also be processed lightly to bring out even more details.

The set up, though admittedly bulky by conventional spotting scope standards, could quite easily be erected in the field or, better still, in a hide, where it could be used to gather video footage or still images with the right equipment. Observing from indoors, through a clean window is also a distinct possibility, especially at lower powers. The instrument is not weatherproof however, owing to its open-tube design, so may be prone to dewing up but a small, battery-operated fan would extend its longevity in field use.

I believe this provides a very cost effective way(the entire apparatus set me back just a few hundred pounds) of obtaining high quality images compared with a high-end apochromatic spotter.

Food for thought!

Thanks for reading!

A couple of months back, I reviewed an extraordinary compact binocular, the Svbony SV 202 8 x 32 ED, showcased in the Preamble above. Retailing for just under £100(but now being offered for just £90), I was deeply sceptical regarding the claims made by the company, since it was offering an instrument with a raft of sophisticated features, including a magnesium alloy chassis, phase and dielectrically coated Schmidt-Pechan roof prisms and an ED element in the objective. Determined to debunk those claims, I happened to have in my possession another compact 8 x 32 – the Celestron Trailseeker – which also had many of those same features but with the exception of the ED element to compare it to. To my absolute astonishment, the claims made by the Hong Kong based Svbony turned out to be true! What’s more, the addition of the ED objective element pulled the Svbony ahead of the Trailseeker in careful optical testing. Even its ergonomic features proved superior to the very decent Celestron binocular.

Yet, it transpired that Svbony was also offering a larger glass, the SV 202 10 x 42 ED, with the same quality features found in the 8 x 32 model, and for a truly amazing price of £125.99 inclusive of delivery!  After a purchaser of both binoculars kindly posted some video footage of these instruments on YouTube, I became convinced that the larger model was worth investigating also, and sure enough, its larger sibling turned out to be even more exciting to test drive!

So, in this review blog, I’ll be taking the reader through the ergonomic and optical features of the Svbony 10 x 42 ED model, and hope to demonstrate why I think it represents exceptional value for money in today’s market. Indeed, it has given this author serious pause concerning the purchase of a more expensive, ‘top-tier’ 10 x 42 for future field use.

First Impressions:

The beautifully finished Svbony 10 x 42 ED.

The Svbony SV202 10 x 42 ED arrived in a similar package to the smaller 8 x 32 ED model. The binocular ( with objective and ocular tethers attached) was carefully packed away inside a nicely fitting soft case, with a soft lens cleaning cloth, a well written instruction manual, a nice quality padded logoed neck strap. The box itself was nicely made, simple and attractive to look at.

Stop Press: The supplied carry case actually closes properly lol, with the binocular and its carry strap attached. You’ve no idea how few binoculars come with cases that can do just that!

Once I removed the binocular from the case, I was immediately impressed with the build quality. Just like its smaller sibling, the 10 x 42 felt very solid in the hand and was covered in a tough, textured rubber armouring that once again reminded me very much of the Zeiss Terra ED binoculars I had seen. Inspecting the objective and ocular lenses, I could see that the magenta coloured anti-reflection coatings were smoothly applied with no sleeks or pits. Passing a torch inside the binocular showed a nicely machined and blackened interior with no sign of dust, fingerprints or other debris. The exit pupils were round with no signs of truncation and the area around the pupils was nice and black. Nothing to concern me here!

And right eye box.

Ergonomics: 

The Svbony 10 x 42 ED  feels very sturdy in the hand but is surprisingly light weight. Usually, the lighter models in the 10 x 42 class tip the scales at over 700g but this model weighed in at just 698g, which is good news for folk who want to travel light.

The eye cups are wonderfully made, properly machined and twist upwards for non-eye glass wearers. There are three positions in all, with each detent locking rigidly into place. These are top notch eye cups, as good as I’ve seen on models costing several times the retail cost of this binocular.

The very well designed twist up eyecups are nicely machined and covered with a soft rubber substrate.

The centrally located focus wheel is constructed from metal and covered with a finely textured rubber substrate for easy gripping. Focusing is smooth and precise with zero play. It’s a little on the stiff side but very easy to negotiate, and I’m sure this will relax a little further with more frequent use. The focuser goes through 1.75 revolutions from one end of its focus travel to the other. The rubber tethered objective and ocular covers fit snugly over the lenses. I generally don’t use these in the field, but I’m reassured that should I employ them, they won’t fall off easily.

The underside of the Svbony 10 x 42 ED has no thumb rests but neither are they really needed. Note the similarity to the Zeiss Terra armouring.

The metal right eye dioptre ring is also nicely machined and rotates smoothly but has just the right amount of tension to stay rigidly in place. Having taken it in and out of its soft case dozens of times over a few days of testing, it never budged a millimetre. Good job Svbony!

As stated above, the anti-reflection coatings applied to the ocular and objective lenses has a strong magenta hue in broad daylight. They reminded very much of those found on the new Zeiss Victory SF binoculars.

Objective lenses.

Like all good anti-reflection coatings, they ought to nearly disappear when viewed nearly straight on. Can you see the glass in the photo below?

Fur mein freund Hans: Good anti-reflection coatings should show little glare when viewed nearly head on in soft artificial light.

In summary, the ergonomics of this binocular are second to none. Really well made, with a quality fit and feel from the get go!

Optical Assessment

Beginning, as always, with my flashlight test, I directed an intensely bright beam of white light into the binocular and examined the image visually from a distance of about 3 metres away. Like the smaller 8 x 32 model, the result was excellent! There were no annoying internal reflections floating about, no diffraction spikes and no diffused light around the beam. It was clean as a whistle. As usual, I compared the results to my control binocular; a Barr & Stroud Series 5 8 x 42 ED, which displays exceptional control of internal reflections and diffraction spikes. I’m happy to report that the Svbony was fully the equal of it!

Later, after dark, I aimed the Svbony at a bright sodium street lamp and was delighted  (but not surprised) to see that it was clean, crisp with no internal reflections, diffused light and nary a sign of any diffraction spikes. These were great results, especially for such an inexpensive binocular. Indeed, I’ve seen much more expensive instruments fare a whole lot worse in this simple test. Good job Svbony!

These results present a problem for Hans.

Even before I tweaked the dioptre ring for my right eye, I was very impressed with the daylight images I was getting from this binocular. The instrument arrived on a very overcast, dull day, with the worst possible lighting. Despite this set back, I was immediately taken by the sharpness of the image and its very large sweet spot. Colour rendition was very neutral and accurate. Eye placement was easy to optimise and I encountered no blackouts. The image was bright and crisp with excellent contrast. I did encounter some veiling glare under these harsh lighting conditions but I remember thinking to myself; “If this is the worse it could be, it’s really not too bad at all!”

The next day afforded much better, sunnier seeing conditions and I was further able to test the mettle of this Svbony binocular. Early autumn leaves radiated with colour and the image remained pin sharp across most of the field. The images snapped to focus with absolutely no ambiguity – a property I had noted in other high quality binoculars. On a walk by the river, I was mesmerized by the clarity of water flowing around rocks  with beautiful sharpness and very little glare. Later the same afternoon, when some cloud rolled in, I examined the hills located a kilometre or so away, and I did detect some chromatic aberration on the edge of some cliffs against a uniformly bright sky. The result was very interesting because I also had my Barr & Stroud Series 5 8 x 42 ED with me to compare the views. After a few minutes going back and forward between the images, I could see that the Barr & Stroud – a lovely binocular in its own right and my personal favourite 8 x 42 – had better colour correction in the same image, but the Svbony was significantly sharper!

I had seen this effect before in the Leica Trinovid HD 8 x 32. Boy was that binocular sharp but it also showed some chromatic aberration on high contrast targets! More on this later.

Comparing the low light performance of the Svbony 10 x 42 ED with a Carson VP 10 x 42 (right) without dielectric coatings showed the former to have the brighter images.

I wanted to test the brightness of the Svbony 10 x 42 ED in comparison to a binocular with the same specifications but without dielectric coatings and ED glass. So out came my Carson VP 10 x 42. Starting around dusk and continuing into early September twilight, I wanted to ascertain whether or not I could detect a brightness difference between these binoculars, fully expecting the Svbony to deliver the brighter image. Sure enough, I could see a difference!  Looking into some brush under bushes as the light rapidly faded, the Svbony delivered a significantly brighter image under these conditions, affirming that the superior coatings on the Svbony resulted in a higher light transmission than the Carson.  Neat!

In another test, I canvassed the opinion of my maths student, Alexander, who was keen to help in the testing. I set up three 42mm binoculars; a Carson VP 10 x 42, a Barr & Stroud Series 5 8 x 42 ED and the Svbony 10 x 42 ED, as shown below:

Three 42mm roofs compared in broad daylight on the same target; from right to left: the Carson VP 10 x 42,the Barr & Stroud Series 5 8 x 42 ED and the Svbony 10 x 42 ED.

Looking at the trunk of a tree under good mid-afternoon illumination, exactly 20 metres away, I asked Alexander to carefully focus each binocular and judge the sharpness of the images, from worst to best. To make it as fair as possible, I asked him to examine the same trunk at a distance of exactly 15 metres away using the 8 x 42 ED to compensate for its reduced magnification. After a couple of minutes of testing, Alexander delivered his verdict; the Carson was the least sharp, the Barr & Stroud was sharper still, but he declared the Svbony to be the sharpest of all!

Alexander looking through the Svbony 10 x 42 ED.

Then I asked him to guess which one was the most expensive. Naturally enough, Alexander figured that the Svbony must be the priciest. He was quite surprised to learn that his choice was actually the least expensive of the three!

After a few days of using the Svbony 10 x 42 ED on long walks through the woods, along the river bank and through open fields, I began to appreciate the silky smoothness of the focuser. The focus wheel’s slow progression makes precise focusing a breeze, and while it’s more suited to hunting than birding, I was still able to enjoy some amazing glassing moments watching a Buzzard taking to flight from a tall conifer tree on one of my local patches. As I related earlier, the Svbony does show a very small amount of chromatic aberration on high contrast objects, yet it delivers sharper images than a more colour free binocular tested against it. This shows that absolute image quality need not be conflated with the degree of chromatic correction found in the binocular. As a case in point, the reader is invited to study reports made by reviewers of Leica’s flag ship binocular, the Noctivid.

Notes from the field: The Svbony has very decent focus depth for a 10 x 42 roof prism binocular. I measured close focus to be 2.8 metres – longer than the advertised 2.5 metres, but something I wasn’t too bothered with, as I usually do close up glassing using 8x models anyway. The comparatively light weight of this binocular makes it very easy to hand hold in my medium sized hands. The binocular does show some glare in the most demanding lighting conditions, but I learned to control it better by firmly holding my eye sockets to the eyecups to minimise the entry of peripheral light into the optical train. Greens and yellows are especially well accentuated in the Svbony, with the binocular delivering excellent brightness to the eyes, even during fading evening light.

Astronomical Testing

No matter how enthusiastic one feels about a binocular during daylight testing, observing the night sky produces still further insights into the relative quality of the glass. Luckily I enjoyed a couple of good vigils with the Moon out of the sky. Here’s what I found. Although it’s obvious that the Svbony 10 x 42 ED had a large, well-corrected sweet spot as seen in daylight glassing, it becomes much clearer by seeing how bright stars morph as they are moved from the centre of the field all the way to field stop. My first opportunity came on the evening of Saturday, September 11. Examining the bright yellow star, Capella, low down in the northeast at 21:45 local time, I was able to see that it remained pin sharp out to within~15 per cent of the distance to the field stop, beyond which point it started to bloat. But even at the field stop the bloating wasn’t too bad and indeed, I was able to focus most of it out. I consider this to be a very good result, especially for the very reasonable cost of the instrument.  I believe this is attributed to the modest choice of field size employed in the Svbony. Many inexpensive models make the mistake of opening up the field too much, with the result that the outer part of the field becomes noticeably more blurred than the centre of the field. And while the field of view of the Sybnony 10 x 42 ED is not overly restrictive at 6.16 angular degrees, the designers did not fall into the trap of making it too wide. This greatly aids in the aesthetic appeal of the night time binocular field.

Bright stars like Vega, Deneb, Altair and Arcturus, low in the west, showed their colours very faithfully. No secondary spectrum was detected within the large sweet spot. The large and sprawling Alpha Persei Association (Melotte 20) looked magnificent in this 10 x 42, as did the Double Cluster a little higher up in the sky. I enjoyed lovely views of the Great Andromeda Galaxy, the Coathanger asterism and the Engagement Ring, Finally, observing mighty Jupiter low in the south southeast shortly before 10pm local time, I could easily resolve, by just handholding the binocular, all four Medicean Stars to the east of the Giant Planet.

While I had intended to view the Pleaides and Hyades some time later that evening, it clouded over. Luckily though, the next night, Sunday September 12, also turned out to be clear and indeed it remained so for much of the night, well into the wee small hours of Monday morning. Beginning about 23:00 h local time and ending about half past local midnight, I enjoyed a fantastic night observing with the Svbony 10 x 42. Though most of my observations were handheld, lying back in a recliner, I did perform one high resolution test centring Albireo in Cygnus in the field of view with the binocular mounted on my tripod. I was delighted to get a beautiful split of this wonderful colour contrast double, the emerald and golden components showing up faithfully. Indeed, I took the opportunity to micro-tweak the dioptre setting just a little while observing this celebrated binocular double.

I enjoyed splendid binocular views of the globular clusters, M13 and M92 sinking lower in the west in Hercules. High in the east, magnificent Perseus was very prominent and I  once again soaked up the views of Melotte 20, and the Double Cluster. The lovely open cluster M34 stood out beautifully with a good sprinkling of faint stars being easily resolved within its confines. After that I just relaxed and went cruising along the river of Milky Way starlight meandering its way from Cassiopeia in the northeast, continuing through Cepheus, Cygnus, Vulpecula, Sagitta and Aquila now sinking into the southwestern sky.

Before ending the vigil, I moved from by back garden to the front garden, which faces east. The Pleiades was painfully beautiful in this binocular, the stars remaining pin point sharp and pure white as the driven snow. Moving the little asterism from the centre of the field to the edge showed a drop off in illumination of its constituent stars. I found it easier to see this fall off under these conditions than during the day. Nothing bad to report here either, as this is a common feature in even top rated binoculars I’ve tested in the past. Finally, with the Hyades rising over the Fintry Hills to the east of my home I was able to enjoy the horns of the Celestial Bull in their full glory. The field sparkled with stellar jewels of various hues and glories; red, orange, white and yellow. Just lovely!

Conclusions

The Heavens declare the glory of God…. you’ll see it well with this binocular.

I’m so very glad I followed up on reviewing this larger sibling from the Svbony ED binocular duo. The little 8 x 32 ED impressed me, but this instrument is just plain extraordinary! It feels and behaves like a much more expensive binocular. Indeed, I would go so far as to say that it will compete favourably with the best mid-tier binoculars out there… no strings. Optically it reminded me very much of the lovely Leica Trinovid HD I owned and enjoyed some time ago. I don’t  know why it is priced so low, but I do know quality when I see it and this wonderfully designed binocular exudes quality, both ergonomically and optically. Please don’t listen to trolls and optics snobs who do nothing to help their fellow amateurs get as much as a foot up on the ladder, and who spout lies about this binocular, as Hans did in the video linked to in Preamble 1 above. I would encourage others to test out this binocular and spread the word to the wider community. You can purchase this in the USA for as little as $150.00 from Amazon. And if not satisfied, it can be returned and a full refund issued to you.

I’m not interested in buying another 10 x 42. This ticks all the boxes for my purposes.

The Japanese camera giant, Nikon, also manufacture an extensive range of binoculars and spotting ‘scopes for the growing sports optics market. Much of their less expensive models have now been transferred to China but they still manufacture their best gear in Japan. In this blog, I’ll be providing a comprehensive review of one of Nikon’s top tier binoculars – the Monarch HG – and in particular the 8 x 30 compact model. The binocular was purchased(£840) with my own cash and I have no association with any optics company, so what you’ll get here is a completely impartial opinion on its properties.

Packaging & Ergonomics

The Nikon Monarch HG 8 x 30 arrived in a rather plain looking brown box. Inside, the binocular was nicely housed inside a really high quality zipper-closed clamshell case. Everything was packed away nicely and I was surprised to see that Nikon included two different kinds of objective covers. The first has caps that can be firmly pressed into the objective. The other option is to go without them. In this case, Nikon provide the user with simple rubber covers that protect the ends of the barrels but do not include the tethered ends. Since I’m no fan of tethered caps, I elected to replace them with the sleek rubber covers.

The great quality clamshell case that accompanies the Monarch HG 8 x 30 as well as the ocular and objective covers.

The binocular itself is very nicely finished in a leather-like textured rubber that is quite reminiscent of the BL offerings from Leica. The strong Magnesium alloy body provides light weight(just 450g) but enough mechanical strength to meet the tough demands of outdoor work, yet I was left feeling that the armouring was a bit too meagre compared with the thicker rubber offerings found on the very popular Monarch 7 line. I began to wonder just how durable this covering would be going forward, especially while negotiating thick brush and brambles. Personally I would have sacrificed some of the obvious aesthetic appeal of this armouring in favour of something a little bit more practical and bulky.

The Nikon Monarch HG 8 x 30 has a very attractive textured rubber armouring but is a bit too thin for my liking. Note the made in Japan stamping under the left ocular.

The right eye dioptre is very nicely engineered. To adjust it, simply push it up, rotate to the desired position and push it back down to lock it. Unlike less expensive models which possess a similar kind of lockable dioptre, Nikon’s solution is very firm. And unlike what some of the reviewers above have mentioned, I never experienced a situation where it popped up by accident.

The focus wheel is a work of art. Taking just over one revolution to go from one end of its travel to the other, it is silky smooth and completely backlash free, enabling one to easily use just a single finger to execute precise focus. Neat!

The Monarch HG is fitted with a very high quality focus wheel that moves with perfect smoothness. Just one finger is enough to get precise focus time and time again.

While there are no thumb indents on the underside of the binocular, I found I never really desired them. The longish barrels are easy to get my medium sized hands around and the instrument feels solid and stable to man handle. The stiff, single bridge design works perfectly well with a binocular of this size too, and I was able to engage with it using one hand without any difficulty, thanks to the fairly long barrels. Having said that, I’m not a fan of glassing this way, as two hands are always more stable than one!

The eye cups are properly machined metal, with a soft rubber overcoat. They have three positions and lock firmly in place. That said, I have seen similar quality eyecups on much more economically priced binoculars, such that I didn’t consider those of the Monarch HG to be exceptional in any particular way. For example, I felt they were similar in quality to the Celestron Trailseeker  8 x 32 I reviewed some time ago. With an eye relief of 16.2mm, I could image the entire field without glasses, but couldn’t see all the way to the field stops with my eye glasses on, and with the cups fully retracted.

Optical Evaluation: 

Collimation was spot on, as judged by examining the images of a far distant vista in both barrels. Inspecting the exit pupils, I was less than impressed with the amount of light around the eye box of each ocular, as seen in the images shown below.  I expected a little better attention to these details in a binocular marketed as ‘premium.’ For further commentary on this, see the remarks made by the reviewer in Preamble 3 above.

Left ocular
Right Ocular

Performing my simple iphone torch test, I directed an intense beam of white light into the binocular and examined the image. I was disappointed to see a fairly pronounced diffraction spike although internal reflections were very well controlled, with no sign of diffused light around the light source. The same spike was present when I turned the binocular on a bright sodium street light after dark. My control binocular – the Barr & Stroud Series 5 ED 8 x 42 – in comparison, showed no diffraction spikes and even better control of internal reflections.

Right from the get go, I was extremely impressed with the brightness and sharpness of the image of the Monarch HG 8 x 30 in bright sunlight and its enormous field of view ( 8.3 degrees checked on the stars). The image sparkled with high resolution details on everything from flowers, tree trunks and distant hills. The image was unusually immersive. Indeed, comparing it to my Series 5 8 x 42 ED, which exhibits a similar true field size(8.1 degrees), I came away with the distinct impression that the HG was delivering a slightly higher magnification than it really was. I have no explanation for this rather wonderful optical illusion but I witnessed it on too many occasions to discount it as not entirely illusory! The image remained impressively sharp across the vast majority of the field thanks to the built-in field flattening technology, with only a minor amount of distortion seen at the field edge. Looking through many layers of fresh mature Sycamore leaves under a forest canopy against a bright overcast sky, revealed virtually no chromatic aberration. Only at the extreme edges of the huge field of the HG did I detect a trace. Depth of focus was very good in the Nikon Monarch HG 8 x 30 but not quite as good as my Leica Ultravid 8 x 20.

Glare was exceptionally well controlled on this unit – better than my control Series 5 binocular in this regard – and that was also the case for veiling glare. This is best tested by looking at some under growth with the Sun immediately above it. Here too, the Monarch HG 8 x 30 bested my Series 5 control – but it wasn’t like a night and day difference.

But despite scoring very high marks optically in many departments, the little Monarch HG 8 x 30 was not without its issues. The most immediate problem I encountered was blackouts, that is, spherical aberration of the exit pupils. I found it very annoying. Indeed, it was not only present while panning with the binocular but it also showed up quite often as I moved my eye around the enormous field while glassing a fixed target. And while one can learn to minimise these blackouts by paying more attention to proper eye placement, I could never really ‘make it go away,’ as it were. Furthermore, the effect was noted by my wife, as well as by several of my students. Looking through my notes on the Leica Trinovid HD 8 x 32, I also recorded some blackouts but they were few and far between in comparison to this Nikon binocular. Nor was this entirely caused by the small exit pupil (3.75mm), as my little Leica Ultravid 8 x 20, with its smaller exit pupil of 2.5mm, is virtually devoid of this problem. I concluded that these pronounced blackouts must have something to do with the special, wide-angle eyepiece design of the Monarch HG. Indeed, the same blackouts were also mentioned by the reviewer in Preamble 4 above using a 10 x 42 Nikon Monarch HG. In addition, I never encountered these blackouts through a Nikon Prostaff 7s 8 x 30, which, despite its identical  magnification, objective diameter and exit pupil size to the HG, has a simpler eyepiece design and smaller field of view.

Less serious was the observed rolling ball effect I noted for the first time in my binocular testing career, a consequence of artificially flattening the field. It was quite apparent while panning the edge of a forest at a distance, and gave me somewhat of a queasy feeling. That said, I’m confident I could unlearn this effect with more sustained use.

Further Notes from the Field

A stylish companion in the great outdoors.

Close focus of the Nikon Monarch HG 8 x 30 is very good. While advertised at 2m, I measured a significantly closer focus of 1.81m. The vast majority of targets from 20 feet away all the way out to infinity snap to focus merely by moving the focus wheel through about one quarter of a turn of the wheel. Because the focuser is so soft and smooth, I found this activity to be particularly enjoyable. It really is quite impressive!

The image through the HG is impressively bright, with good enough transmission to allow one to continue to glass well into twilight, but ultimately proving inferior to a decent 8 x 42 in similar low light conditions. Nikon claims a light transmission of 92 per cent, but two spectrophotometric measures on the 8 x 30 and 10 x 42  show slightly lower values of 90.1% and 88.3%, respectively. That said, the light curves look almost identical and show a nice, flat profile over the most important visual wavelengths, peaking in the red.

Astronomical Tests

The 8 x 30 format is about the minimum aperture required to really enjoy the night sky. Smaller binos are all well and good for the Moon and some of the brightest deep sky objects, but you go a whole lot deeper moving from 20-25mm up to 30mm. The Moon looks very sharp, bright and colour free through the Nikon Monarch HG 8 x 30, but I did notice a trace of the 4 diffraction spikes emanating from the Moon during waning gibbous under good, transparent conditions.

Testing on a rich star field like the Alpha Persei Association afforded a good opportunity to test for field flatness/curvature. Canvassing the help of a former student of mine and keen amateur astronomer, we noted that the field is not perfectly flat to the field stops in the Nikon Monarch HG. Stars remained very tight out to about 75 per cent of the field, with distortion increasing rapidly in the last 25 per cent of the field. That said, in most situations, the stars remained acceptably sharp over the entire field, so should be an enjoyable companion under the starry heaven.

Moving a last quarter Moon from the centre to the edge of the field of the HG did reveal a small but significant darkening of the maria which provides strong visual evidence for a drop off in illumination in the outer 20 per cent of the field. I found it very difficult to discern these changes during tests conducted in broad daylight.

Conclusions

A birder’s dream bino?

For some folk, the Nikon Monarch HG might well be a birder’s dream binocular, with its very sharp, contrast-rich and extremely wide and flat field of view. For me though, I feel the blackouts are a major issue which would make me somewhat leery of paying the relatively steep retail price for these binoculars. This concern isn’t just confined to the Nikon Monarch HG though, as another reviewer mentioned how the same phenomenon completely put off his daughter while testing the Zeiss Victory SF 10 x 32, so any potential buyers will be strongly advised to try them out before buying. I find it a little alarming that some of the reviewers presented at the beginning of this blog never even mentioned this effect! What’s more, the small size of the Nikon Monarch HG 8 x 30 may not suit those who have large hands. In addition, the rolling ball effect, while mild in this binocular, may deter others in favour of models that do not have field flattening technology. In the end, the decision lies with you!

Make no mistake about it; we live in a golden age for buying binoculars. Never before has the consumer had so much choice available, thanks to incredible advances in optical technology which has given many other individuals access to very decent optics for a small financial outlay. In recent years, new coating technologies have greatly increased light transmission and image sharpness, to such an extent that even the budget models now available can and do outperform premium models offered only a few decades ago. In addition, the incorporation of extra low dispersion(ED) glass is now common even in inexpensive models, which, if executed properly, promises to cut chromatic aberration and increase image contrast still more.

As I’ve commented elsewhere, the 8 x 32 format is the new 8 x 42, as evidenced by the offering of the former by both mass market and premium binocular manufacturers alike. This is in no doubt attributed to their lower mass, improved ergonomics and very efficient light transmission, as well as their perfect suitability during bright daylight but also well into low light situations encountered at the earlier stages of dusk and dawn.  Apart from the use of premium pocket glasses – my personal favourite format – the 8 x 32 format has always interested me, owing to its compactness and smaller exit pupil (4mm), which uses the best part of your eye to analyse the binocular image.

While many entry-level ED models are priced in the £250 to £300 range, I became very intrigued by a less well known manufacturer, Svbony, a Hong Kong-based optics firm that has recently marketed a compact and mid-size model – an 8 x 32 and 10 x 42 –  chock full of advanced features. But what really piqued my interest was that Amazon UK were offering the 8 x 32 ED model for just £99.99, inclusive of delivery! As you can see from the specifications above, the Svbony 8 x 32 ED has a number of advanced optical features that I simply wouldn’t expect in a model at this price point, but having another binocular available – the Celestron Trailseeker 8 x 32(retail price £146 UK) – that also possesses many of the same features – I was able to conduct an in-depth study of how the Svbony ED binocular compared with it.

Ergonomics Comparison

The Svbony 8 x 32 ED(right) and the Celestron Trailseeker 8 x 32(left).

No doubt you’ve heard that possessing a magnesium alloy frame is a feature only common to upper-tier binocular models, I would like to take this opportunity to put this urban myth to bed, once and for all. Since both the Svbony and the Celestron Trailseeker models feature a magnesium body in this low price category, having this design feature is no longer the preserve of the best models but is now commonly available even in much more economically priced products.

The Celestron Trailseeker has a large plastic focuser that becomes very hard to move in Winter owing to the solidification of the grease used in its gearing. But in warm weather, it becomes much easier to turn. In contrast, the lower priced Svbony 8 x 32 ED has a much higher quality metal focus wheel, which is much smoother and easier to turn. Taking just one and a half revolutions to go from one extreme of its focus travel to the other, I would describe it as slow to progressive in speed, so not especially suited to either birding or hunting – more of a general purpose instrument than anything else.

Turning now to the dioptre ring located under the right ocular in both models, the Svbony’s metal dioptre ring is better designed than the plastic one found on the Trailseeker. Looking at a close up of the Svbony dioptre, you can see that the markings are easier to make out, helping the user achieve his or her optimum position better. And just like the Trailseeker, the Svbony dioptre ring is stiff and thus will not get nudged out of position so easily during field use.

The lower-priced Svbony model has a higher quality dioptre ring compared with the Celestron Trailseeker.

Looking next at the quality of the eyecups, I was delighted to see that the Svbony had good, high quality rubber-over-metal twist up cups, pretty much identical in quality to those found on the more expensive Trailseeker. What is more, they stay rigidly locked in place when fully extended. Yet again, that the Svbony possessed such high quality eye cups was a pleasant surprise to me, as I was not expecting anything as good as that on a compact binocular costing less than £100.

The matt black armouring on the Svbony is a little bit more grippy than the Trailseeker and the ribbing at the side of the former reminds me very much of the armouring found on the Zeiss Terra ED models I’ve sampled.

The ribbed side armouring on the Svbony 8 x 32 ED is very reminiscent of that found on Terra ED models.

The objectives on both the Svbony and the Trailseeker are equally well recessed to protect the glass from dust, rain and peripheral light. The anti-reflective coatings look to be completely different though, with the Trailseeker having a standard greenish reflection in bright daylight, as opposed to the more subdued purple hues seen on the Svbony.

The objective lenses on both models are nicely recessed but appear to have entirely different anti-reflection coatings applied. The Svbony model is at the top.

Overall, the Svbony 8 x 32 ED feels slightly lighter and more comfortable to use than the Celestron Trailseeker 8 x 32, which is a bit more ‘clunky’ in comparison, at least in my medium sized hands. That, together with the noticeably better focus wheel and dioptre ring on the former means that, from a purely ergonomic perspective, the lower-priced Svbony is the clear winner.

Optical Comparisons

Good ergonomics, of course, count for nothing if the optics are not up to scratch, so how well would the £99.99 Svbony 8 x 32 ED fare in comparison to the Celestron Trailseeker 8 x 32? Having reviewed the Trailseeker some time ago, I was quite impressed with how well it handled a beam of intense white light directed into it from my iphone. That’s because the same model is fully broadband multi-coated and has super-high reflectivity dielectric coatings applied to its Schmidt-Pechan roof prisms. I’ve seen similar results on dozens of high quality binoculars and so I expected the Svbony to yield good results too, if indeed it has those same coatings.

My efforts confirmed that the Svbony also passes this test with flying colours! Specifically, the image was devoid of any significant internal reflections and with no diffused light around the beam, which often betrays the use of lower quality optical components introduced into the optical train. What is more, while the Trailseeker did show a weak diffraction spike, the Svbony had none. Indeed, I would place the Svbony slightly ahead of the Trailseeker, based solely on the flashlight test. So far so very good!

But the good news only continued when I performed a daylight comparison test of both the Svbony ED 8 x 32 and the Celestron Trailseeker 8 x 32 . While both models have effectively the same field of view(7.87 degrees), I felt that the Svbony provided a slightly sharper image than the Celestron, with better contrast and improved control over veiling glare. Both instruments have a large sweet spot but edge of field performance was a little soft in both models, as was the degree of field curvature seen. Chromatic aberration, although quite low in the Trailseeker, was better handled in the Svbony under the same conditions. Whatever ED glass elements are present in the Svbony, it seemed to be doing its job well. Depth of focus in the Svbony 8 x 32ED  is also good; a real plus if you’re a prospective birder. Close focus is just under two metres(1.98m measured).

Another way to ascertain whether similar coating technologies were applied to both the Svbony and the Celestron Trailseeker, is to perform a low light test by comparing the brightness of the image in both instruments at dusk. On paper, I expected both to behave rather similarly, and that is exactly the result I achieved. Both 32mm models produced a more or less equally bright image, with perhaps the nod going to the Svbony! As I have shown in many other comparisons, the ED element may have conferred a slight advantage to the Svbony in these challenging conditions but as expected, it was marginal if anything.

………………………………………………………………………………………………………………….

Note Added in Proof: If you go back and listen to the optics trade review of the GPO Passion ED 8 x 32 linked to above, the presenter informs us that GPO did not use ED glass in their largest 56mm models, citing their reasons in relation to the lack of chromatic aberration seen in low light environments. If ED glass really had a significant low light advantage, don’t you think they’d mention it or go ahead and use it? And why do so many binocular reviewers(in published magazines too) I have come across still perpetuate this myth?

………………………………………………………………………………………………………………………….

Examining the 4mm diameter exit pupils on the Svbony showed nice, round pupils with no signs of truncation. There was also a nice periphery of blackness immediately around both pupils,  which contributes to the high contrast images I detected during my daylight tests.

Concluding Comments

The Svbony 8 x 32 ED  was a very eye-opening and pleasant experience. In terms of both optical and mechanical properties, it proved superior to the Celestron Trailseeker. Indeed, I would put the Svbony more on par with the new Celestron Trailseeker ED, though I’ve not actually tested this model. The very few realistic reviews I’ve seen of the Svbony  8 x 32 ED claim that it performs like models double or triple the price; a sentiment that I wholeheartedly agree with.  And at a retail price of less than £100, there is very little in this binocular that I can find fault with.

Very highly recommended!

Post Scriptum: I performed a measurement of the field size of the Svbony 8 x 32 ED just after local midnight, July 22. Turning to the Plough (Big Dipper) asterism high in the northwest, I was just unable to fit Phecda and Merak into the field of view of the binocular. These are separated by 754′ or 7.9 angular degrees, so I’m confident that the stated field size(7.87o) for this binocular is fairly accurate.

Pentax is a company long synonymous with good optical quality. Over the last few years, I’ve reviewed a few models manufactured by this company, ranging from the very small(6.5x 21) to the very large(20x 60). In particular, I’ve included an earlier incarnation of the  20 x 60 SP model in my own personal arsenal of binoculars, where it’s employed in deep sky observation and regular white light solar observing. So, I was excited to see how its smaller sibling, the 10x 50 SP WP, would shape up in field tests.

First Impressions

I purchased the binocular with my own money and it set me back £170, inclusive of delivery charges. The binocular arrived double boxed, including the instrument itself, packed inside its soft case, together with plastic end caps for both the ocular and objective lenses, a logoed padded next strap and instruction sheet containing information concerning the warranty. The plastic caps that protect the optics of the 10 x 50 SP looked identical to those that accompanied my 20 x 60, and together with the woefully inadequate soft case, represent the weakest links in the entire package. The caps are loosely fitting and invariably fall off  when the binocular is picked up. As for the case, it does very little to protect the binocular from serious knocks so should really be upgraded to either a padded soft case or better still, an aluminium hard case to protect your investment.

Ergonomics

Thankfully, my initial impressions of the binocular itself were far more favourable. When I unpacked it, I was immediately struck by its rugged build quality. The binocular weighs in at a hefty 1kg and is covered with a thick layer of synthetic rubber identical to that found on my 20 x 60 . Like its bigger brother, it has a lockable focuser; simply push the wheel forward and it disengages with the internal gearing, preventing the wheel from being moved. Although not an essential feature by any means, I can see where it would come in useful if one observes targets at a fixed distance from the user or when observing the night sky, where all the subjects are located more or less at infinity.

The central focus wheel is very easy to grip and is lockable simply by pushing it forward.

The twist up eyecups are very well made and very comfortable to use. There are three positions; fully down, intermediate and fully extended. Eye relief is a very generous 20mm. Usually, I observe with the eye cups fully extended but I actually found the view to be most comfortable and immersive at the intermediate position without wearing eye glasses.

The very solid twist up eye cups are comfortable to use and have three positions. Eye relief is generous allowing those who wear glasses to fully engage with the entire field.

The ‘WP’ part of its name, I assume, refers to ‘Water Proof,’ with a specified JIS class 6 rating. The instrument is purged with dry nitrogen gas to prevent internal fogging and is O-ring sealed. The dioptre ring is located under the right ocular lens and is negotiated by moving an easy to access lever which can be adjusted clockwise or anti-clockwise. It is reasonably stiff to the touch so should hold its position well. The underside of the 10x 50 SP WP has two large thumb indents for easier hand holding. I found that my thumbs naturally rested in them while holding the binocular up to my eyes.

The focus wheel is very stiff; a strict no-no for birding or any activity that requires rapid focus changes. But for stargazing or for stationary targets located in the distance, it works just fine.

You’ll find two large thumb rests on the underbelly of the binocular for more secure gripping.

Optics

The proof of the pudding, of course, lies in the eating, and this is where this well-made classic Porro prism binocular really shines. The SP series underwent an upgrade from the first generation models, with better multi-layer anti-reflection coatings being applied throughout the optical train. Allbinos tested this model out and measured a light transmission value of about 85%, which is very good indeed considering the modest price tag on this binocular, as well as the fact that some of the world’s best Porro prism binos achieve about 95% or so.

Not for the Birds

Inspecting the innards of the instrument in broad daylight showed it to be clean and dust free. Setting up my iphone torch to its highest setting in my back garden at dusk and placing it a comfortable distance away revealed a few minor internal reflections and no diffraction spikes or diffused areas; another good result indicating that all was well with the instrument in keeping bright light sources under control. Placing the beam just outside the field of view showed very little ghosting so this will be a good binocular to observe bright objects in the night sky such as the full Moon and stars located near it. It will also garner excellent views of cityscapes at night. Close focus was measured to be about 5.3 metres – a little better than advertised but nothing to write home about. The coatings on the ocular and objective lenses seem to be very evenly applied. In addition, the objective lenses are very deeply recessed which helps protect the optics from the vagaries of the British climate and also cuts down on stray light.

Very evenly applied multi-layer anti-reflection coatings applied to the objectives help transmit a decent amount of light through the optical train.

In broad daylight, the view through the Pentax 10x 50 SP WP is very impressive, with great contrast, good colour rendition and good but not outstanding control of glare. Depth of focus is not bad, but the 3D pop that Porro prism binoculars are famous for was there in spades. Colour correction is excellent, even off axis, where one can detect a small amount of lateral colour. Field curvature is very gentle but does show a fairly minimal amount of pincushion distortion near the field stops. Even though the field of view is fairly narrow at 5 angular degrees, it didn’t feel overly restrictive to my eyes. At just over 1kg weight and delivering a 10x optical boost, these are not binoculars that one could handhold for long but it’s certainly possible to scan the landscape and night sky for a few minutes before some fatigue sets in. These are however, perfect for use on a lightweight monopod or tripod for ultra stable viewing.

Further testing at dusk showed excellent control of internal reflections and clean, crisp images garnered from a bright sodium street lamp. Placing the lamp just outside the field of view showed up no significant off-axis flares. Placing the binocular on a light weight monopod and turning them on the night sky also served up excellent results. Centring the bright Summer luminary, Vega, in the binocular field and focusing in showed a pinpoint sharp image with no secondary spectrum and with no diffraction spikes. Better still, moving the star to the edge of the field induced only a little distortion and some lateral colour(purple fringing), indicating that the aspherical optical element built into the eyepieces of the Pentax SP binocular were doing their jobs well. And while the skies were far too bright to provide a more in-depth study, with strong Summer twilight upon us here in central Scotland,  I compared and contrasted the view through the Pentax 10 x 50 and my trusty Barr & Stroud Series 5 8 x 42 mounted on a second monopod. Turning my attention to the well placed Coathanger asterism in Vulpecula revealed a cleanly resolved view in both instruments, but with fainter stars showing up better in the Pentax, albeit in a smaller true field.

Conclusions & Recommendations

In recent years, thanks to great advances in technology, there has been a steady movement within the amateur community towards roof prism designs over older, Porro prism binoculars. But after spending a few weeks testing out this affordable model from Pentax, I was genuinely surprised and delighted by its optical performance. Indeed, you’d have to fork much more money for a roof prism binocular with the same specifications as this Pentax to get the same optical quality. The only real advantage of the roof prism incarnations at 10 x 50 are their lower mass(but not by much) and slightly smaller frames. Having sampled a few inexpensive and mid-priced 10 x 50 roof prism binoculars in the past, I can say hand on heart, that they did not deliver the light transmission values anywhere near those attained by this classic, affordable 10 x 50. Indeed, I would strongly recommend readers to look more closely at tried and trusted Porro prism designs in aperture classes of 50mm or above over the roof prism varieties, especially now that they come with full waterproofing.

Qui bono?

Amateur astronomers looking for quality deep sky views on dark, clear nights, and casual daytime viewers with permanently set-up tripods or monopods surveying targets set in the distance. Remember that five degrees is still plenty good enough for the vast majority of deep sky observing! These would work very well in holiday cottages set by a lake or overlooking a picturesque valley floor. And although they can be handheld for short excursions, they do benefit greatly from mounting.

Very highly recommended!

Ezekiel 20:6

Any unbiased reading of the Bible will soon reveal that the Creator of the Universe has had a long and enduring relationship with the Jews. This people group were the first humans to forge a relationship with God, where He made Himself known to them and guided their founding of a nation in a relatively tiny strip of land on the eastern shores of the Mediterranean Sea. The Biblical narrative accurately portrays much of the history of the ancient Jewish nation and modern archaeological research is unveiling more and more details that affirm the historicity of their story, despite militant opposition from secular academics, who have been proven wrong time and time again.

Originally the land promised to the Jews by God actually stretched from the Nile to the Euphrates:

In the same day the Lord made a covenant with Abram, saying, Unto thy seed have I given this land, from the river of Egypt unto the great river, the river Euphrates: The Kenites, and the Kenizzites, and the Kadmonites,  And the Hittites, and the Perizzites, and the Rephaims, And the Amorites, and the Canaanites, and the Girgashites, and the Jebusites.

Genesis 15:18-21

God explicitly states the extent to which the Jews could legitimately call their land in the Second Book of Moses, called Exodus:

I will set your boundary from the Red Sea to the sea of the Philistines, and from the wilderness to the Euphrates River; for I will hand over the inhabitants of the land to you, and you will drive them out from you.

Exodus 23:31

We also read the same thing in the opening passages of Joshua:

Cross the Jordan River. Lead these people into the land that I am ready to hand over to them .I am handing over to you every place you set foot, as I promised Moses. Your territory will extend from the desert  in the south to Lebanon in the north. It will extend all the way to the great River Euphrates in the east (including all Syria) and all the way to the Mediterranean Sea in the west. 

Joshua 1:2-4

Because of their unfaithfulness to their God, the former glory of the kingdom established by David and his son, Solomon, was gradually but inexorably wrenched from them because of their reluctance to follow Torah, as well as their eagerness to seek out and worship the false gods of the surrounding nations and the inter-marriage of their nobles with the nobility of foreign cultures(and against God’s wishes). As a result, ancient Israel and Judah suffered many waves of conquests by foreign imperial powers including Assyria, Babylon, Persia, Greece, Rome, Byzantium and the various waves of Islamic invasions over the centuries and millennia. Israel ceased to be a free nation about 2,600 years ago being occupied by foreign powers throughout much of this time.

The Mereneptah Stele, dating to the 13th century BC, has the earliest known reference to Israel as a nation inscribed on it. Image credit: Wiki Commons.

For much of its history, the Jewish people have suffered terrible persecutions under various powers, culminating with the attempt of the evil Nazi regime to exterminate them from the face of the Earth. Still, despite these perils, they have bucked all the odds to maintain their culture and religion; indeed they are the only truly ancient people that exist through modern times. After World War II, the United Nations created a homeland for the remaining Jews, which culminated in the declaration of independence of the modern state of Israel on May 14 1948. The declaration was immediately condemned by all the surrounding Arab nations and was immediately attacked, leading to the Arab-Israeli War (1948-9). No superpowers came to the aid of the young nation but miraculously, the Israeli’s won. Less than twenty years later, Israel was once again attacked by a coalition of Arab nations including Syria, Jordan and Egypt in June 1967. Though attacked on three different fronts and greatly outnumbered in terms of troops, tanks and aircraft, the conflict lasted just six days, with Israel, miraculously, emerging victorious. Thus, Israel had to work hard from the outset to establish its borders, rapidly developing an excellent military machine that staved off aggressive behaviour by its surrounding enemies, and which remains so to this day.

In the 73 years since its founding days, the story of Israel has been one of astonishing prosperity, so much so that many Bible believing Christians accept it as a clear and unambiguous miracle in our times. Furthermore, it is clear that while the majority of contemporary Jews do not accept Jesus as their Messiah, the Lord would not make a complete end of them, but established them again for the sake of a minority who have(or will) come to accept Christ as their Lord and Saviour. Furthermore, the Bible foretells that this tiny little nation will play an important role in converting many unbelievers to the true God during the Great Tribulation period, otherwise known as the time of Jacob’s Trouble.

Most denominational Christians however, have been taught the false doctrine of replacement theology, which assumes that the modern Church has taken the place of Israel, and as a result, know very little about how Israel will play a central role in God’s ultimate plan for the salvation of many people. This was essentially my thinking for most of my life, as I continued in my walk with the Catholic Church, being largely ignorant of Biblical knowledge. We had no Bible in our home(my neighbours had none either), and no Sunday Schools when I was growing up. Indeed, I saved up some pocket money to buy a children’s Bible in my youth and only purchased my first ‘real’ Bible:- an old King James Version:- as a graduate student during my time at the University of Dundee in the mid-1990s. But this is equally true of many Protestant denominations, which teach nothing at all concerning the true role of Israel in God’s redemptive plan for humankind. Only when I began to read the Bible for myself, as a non-denominational Christian, that I rejected the notion of replacement theology.

With the Lord, there is the Church and then there’s Israel; they are not one and the same.

With Israel, it’s personal.

Consider the particular interest our Lord has expressed in the land of Israel;

For the land you are going in to possess is not like the land of Egypt from which you came. There you planted your seed and watered it by foot, like a vegetable garden.  But the land you are crossing over to possess is a land of hills and valleys, drinking from the rain of the heavens it drinks in water.  It is a land that Adonai your God cares for—the eyes of Adonai your God are always on it, from the beginning of the year up to the end of the year.

Deuteronomy 11:10-12

The prophet Ezekiel writes:

Therefore say to the house of Israel: Thus says the Lord God: Not for your sa ke do I act, house of Israel, but for the sake of my holy name, which you desecrated among the nations to which you came.

Ezekiel 36:22

So what’s it all about then? In a phrase, the execution of Absolute power!

Israel is God’s land; He gave it to the Jews.

The prophet Jeremiah writes:

Thus says the Lord, “If My covenant for day and night stand not, and the fixed patterns of heaven and earth I have not established, then I would reject the descendants of Jacob and David My servant, not taking from his descendants rulers over the descendants of Abraham, Isaac and Jacob. But I will restore their fortunes and will have mercy on them.’”

Jeremiah 33: 25-26

In other words, the Lord would sooner abolish the laws of nature than renege on His promises to Israel.

In Ezekiel 37, God states explicitly that His covenant with Israel is for all time:

I will make a covenant of peace with them; it will be an everlasting covenant. I will establish them and increase their numbers, and I will put my sanctuary among them forever.

Ezekiel 37:26

So let’s take a closer look at the remarkable rise of Israel in the modern psyche. As a nation state, Israel is tiny,  with a land area of just 21,000 square kilometres, smaller than Wales(or the US state of New Jersey)  and ranking about 150th out of the 200 or so nations on Earth. It’s population is currently 9.76 million, of which 75 per cent identify as Jew. But with antisemitism on the rise worldwide it is estimated that as much as half the entire global population of Jews will be living in Israel by 2030.  The Gross Domestic Product (GDP) of Israel is $564 billion, but Its per capita annual income is even more impressive, at $58,2700 per annum, making its citizens the 13th richest nation in the world. Indeed, according to the Economist, Israel was ranked the 4th most successful economy in the world as of 2022. Israel is also home to more millionaires per capita than any other country in the world, with over 7,200 millionaires with collective assets of approximately $45 billion. What’s more, Israel’s economic wealth far exceeds that of all the surrounding (Muslim and non-democratic) nations. The life expectancy of the average Israeli is 83.5 years, where it polls as the 10th longest among the other nations of the world. Israel’s age demographic though is astonishing and contrary to every other developed nation currently in existence. 25 per cent of the population are under the age of 14 and 40 per cent are aged 25 years and younger. Only 11 per cent of the Israeli population is aged 65 years and older!

This very youthful population is also highly educated; 45 per cent of Israeli’s hold a Bachelor’s degree or its equivalent; higher per capita than any other nation on Earth. Their official language is Hebrew, for centuries considered an all but dead language, but thanks to the efforts of Jewish linguists, is now widely spoken and thriving. Curiously, though Israel is one of the most technologically advanced nations currently in existence, her citizens are taught little or nothing about Darwinian evolution in public schools, which dovetails with the ideology’s current fall from grace as a proper science of origins. And yet, Israel is a shining light in the emerging biotechnological and agricultural industries, both of which require an excellent knowledge of the life sciences.

Because of more or less incessant terrorist threats from foreign regimes, Israel has one of the best trained professional armies in the world. The so-called Israeli Defence Forces (IDF) has about 150,000 full-time members and over 400,000 reserves. All Israeli citizens over the age of 18 are obliged to undergo two years and eight months of military service for men and two years for women, although many seek exemptions on religious, psychological and physical grounds. This rise in military power also comports with the Biblical narrative, which describes the desolate land of Israel being revived from a “valley of dry bones”(see Ezekiel 37):

So I prophesied as He commanded me, and the breath came into them, and they came to life and stood on their feet, an exceedingly great army.

Ezekiel 37:10

Despite more than half of the land being desert and only 20 per cent being arable, Israel is a world leader in irrigation technology. In addition, it’s de-salination technology is now being exported to other nations (the US state of California, for example, is now steeply committed to using these technologies). The north of the country receives a plentiful supply of rain but the south is much more arid, with the result that water transport and use is carefully regulated. The statistics are impressive; agriculture’s share of total water use fell from more than 70% in 1980 to 57% by 2005, and is projected to drop to just 52% by 2025, according to a recent report. Many nations around the world have benefitted greatly from Israel’s lead in this regard. Indeed this small nation has become the fruit basket of Europe and the Middle East, growing and exporting over 40 different types of fruit. Indeed, 95 per cent of all Israel’s food is homegrown, supplemented by imports of meat, grains, coffee, cocoa and sugar. Israel also produces most of the flowers sold in Europe(especially during the winter months), with an industry estimated to be worth $60 million. These flowers are almost exclusively grown on 214 hectares of land.

Just as the Bible informs us, Israel has truly become “a land of milk and honey.” Specially bred, disease-resistant cows produce the highest amounts of milk per animal in the world, with an average of 10,208 kilograms of dairy in 2009, according to data published in 2011 by the Israeli Central Bureau of Statistics, outperforming cows in the US (9,331 kg  per cow), Japan (7,497), the European Union (6,139) and Australia (5,601). Honey production in Israel is prodigious, with more than 100,000 apiaries scattered across the country and exported to many other nations around the world. And despite the alarming decline in bee numbers in almost every other country, Israel’s bee populations have not endured such decimation, thanks to the implementation of a number of ingenious management strategies. Indeed, the Israeli department of agriculture estimate that the value of their bees as vehicles of pollination is worth more than 30 times the value of the honey they produce! In 1948, only about 400,000 acres of land in Israel could be tilled. Today it stands at over a million acres, with productivity increasing by a factor of 16 per unit of water used. And instead of growing strains of wheat that are waist high, as is the case in most other nations, Israeli farmers cultivate new varieties that only grow to knee height and so require far less water to bring them to maturity.

In the spheres of technology, Israel ranks as the 8th most powerful nation in the world. Outside of Silicon Valley, California, Silicon Wadi on the coastal plains just outside Tel Aviv  has the highest number(over 3,000 as of 2019) of IT start-up companies in the world. The first anti-virus software was formulated here, as was the first voicemail technology, and all manner of memory sticks that we use in our everyday lives. Motorola, Microsoft, Celebrite and Intel all have major investments here. The oil industry is booming at an unprecedented rate in Israel with valuable, high-grade crude oil and natural gas reserves found in the Negev, the Golan Heights and most recently off shore in the Leviathan and Tamar fields. Analysts suggest that the energy reserves in these newly discovered sites could power the nation for another 300 years! What’s more, it is expected that Israel will become a major supplier of petrochemicals to the European nations by building under-sea pipelines across the Mediterranean.

In recent years, geologists have assessed Israel’s mineral wealth. In particular the rapidly evaporating Dead Sea has an estimated $5 trillion of minerals salts including, calcium, sodium, magnesium and potassium chlorides, bromides and iodides, phosphates and other resources. Even the mud dredged up from the Dead Sea floor has important medicinal properties that many people will pay for. Moreover, an extremely rare mineral, Carmeltazite, hitherto thought to form only in outer space was recently found in Israel, which, owing to its rarity, is potentially more valuable than diamond.

By most anyone’s standards, the story of the re-birth of Israel is a remarkable phenomenon. Look how much they have achieved in only one human generation! But all of this was foretold in the prophecies of Ezekiel, most likely dated to 7th century BC:

Thus says the Lord God, “On the day that I cleanse you from all your iniquities, I will cause the cities to be inhabited, and the waste places will be rebuilt. The desolate land will be cultivated instead of being a desolation in the sight of everyone who passes by. They will say, ‘This desolate land has become like the garden of Eden; and the waste, desolate and ruined cities are fortified and inhabited.’ Then the nations that are left round about you will know that I, the Lord, have rebuilt the ruined places and planted that which was desolate; I, the Lord, have spoken and will do it.”

Ezekiel 36:33-36

And yet, the Biblical narrative also suggests that this new-found prosperity will attract the eyes of power-hungry nations surrounding it, like a proverbial moth to a brightly lit lamp:

After many days you will be summoned; in the latter years you will come into the land that is restored from the sword, whose inhabitants have been gathered from many nations to the mountains of Israel which had been a continual waste; but its people were brought out from the nations, and they are living securely, all of them. You will go up, you will come like a storm; you will be like a cloud covering the land, you and all your troops, and many peoples with you.”

‘Thus says the Lord God, “It will come about on that day, that thoughts will come into your mind and you will devise an evil plan, and you will say, ‘I will go up against the land of unwalled villages. I will go against those who are at rest, that live securely, all of them living without walls and having no bars or gates, to capture spoil and to seize plunder, to turn your hand against the waste places which are now inhabited, and against the people who are gathered from the nations, who have acquired cattle and goods, who live at the centre of the world.’ Sheba and Dedan and the merchants of Tarshish with all its villages will say to you, ‘Have you come to capture spoil? Have you assembled your company to seize plunder, to carry away silver and gold, to take away cattle and goods, to capture great spoil?’”’

Ezekiel 38:8-13

The Bible also asserts that Israel is the centre of the world as God sees things:

Thus says the Lord God, ‘This is Jerusalem; I have set her at the centre of the nations, with lands around her.

Ezekiel 5:5

And when we look at Israel’s geographic location, it indeed lies at the hub of three continents; Africa, Europe and Asia.

The Bible also confidently predicts that Israel will always attract trouble makers and that eventually all the nations will be gathered against her under the auspices of the Anti-Christ:

It will come about in that day that I will make Jerusalem a heavy stone for all the peoples; all who lift it will be severely injured. And all the nations of the earth will be gathered against it.

Zechariah 12:3

The Book of Jeremiah also makes it clear that when the Jews come back in the land after being scattered among the nations, they will do so without the ark of the covenant:

Then it shall come to pass, when you are multiplied and increased in the land in those days,” says the Lord, “that they will say no more, ‘The ark of the covenant of the Lord.’ It shall not come to mind, nor shall they remember it, nor shall they visit it, nor shall it be made anymore.

Jeremiah 3:16

And what do we see today? Israel back in the land without the ark! This was quite simply unthinkable at the time it was written, since it was indispensable to their worship.

What is more, the ancient nation of Israel was divided up into two kingdoms- the northern territory of Israel, and the southern territory of Judah, in the reign of king Jeroboam I,  and remained so. But the prophet Jeremiah informs us that when the people come back in the land in the latter days, there would no longer be such an administrative division:

In those days the people of Judah will join the people of Israel, and together they will come from a northern land to the land I gave your ancestors as an inheritance.

Jeremiah 3:18

What is the ‘northern land’ referred to in this verse of Scripture?

It could well be Russia, as some 1.2 million Israeli citizens originated there.

Isn’t the Bible remarkable for its accuracy? Surely, we are living in the times of fulfilled prophecy!

Already, we can see this gradual build-up (a Biblical “hook in the jaw”) with the hatred expressed by the politicians of many countries toward Israel as well as pervasive antisemitism(an irrational hatred of the physical descendants of Abraham, Isaac and Jacob, which is both trans-generational and global in reach). Sadly, one of Israel’s greatest enemies is the United Nations(UN)(Indeed, in light of its abject moral failures – a consequence of abandoning the Biblical God and the overwhelming archaeological evidence for the Jewish right to the land uncovered in recent years – it ought to be renamed the United Nothing). For example, Syria bombs its civilians with chlorine gas, China tortures dissidents, Venezuela restricts access to food, and Burma is engaged in the ethnic cleansing of its Muslim minority. Yet despite these atrocities, the UN Human Rights Council trains the bulk of its diatribe on, you’ve guessed it, Israel!

At the time of writing, 31 UN members don’t recognise the state of Israel. Additionally, the nations of Bolivia, Mali, Mauritania, Niger, Qatar and Venezuela have suspended ties to Israel. Most of these nations do not want the state of Israel to exist. There are also several countries, most notably Egypt, that recognise the state but almost always vote against it. That is how far-reaching the Israeli-Palestinian conflict has become!

The UN has chosen to oppose Israel at nearly every turn because of the influence and encouragement of all of these member states. On the UN security council, Israel has the support of the U.S’s power of veto and is therefore safe from most harmful resolutions, but in the general assembly the anti-Israel countries almost always win out. The most recent example of this was the decision to condemn the United States for recognising Jerusalem as Israel’s capital even though they have every right to claim it as their own. That resolution overwhelmingly passed. But if the UN were nicer to Israel, every Muslim majority country in the world (except Albania and a few others) would withdraw from the organisation and thus would lose all of its influence over the Muslim world. There would be no more peacekeepers in Syria and Iraq, no nuclear weapons inspectors in Iran, etc. To my mind, the UN has strategically chosen to alienate Israel, over dozens of others. As a result, most Israelis are rightly suspicious of the UN to the extent that it’s somewhat of a mystery why they haven’t yet severed all ties with the organisation.

The so-called ‘Palestinian conflict stems from the claim that Palestinians are a valid ethnic group of people who occupied the land along with the Jews. But this claim is a complete lie, as anyone who has studied classical history can attest. Not once is the term ‘Palestine’ referred to in the Bible. Indeed, it actually derives from about 135 AD, when the Roman Emperor Hadrian (reigning from 117-138 AD), who in the aftermath of the Bar Kokhba Revolt, laid waste Jerusalem and ostracised the Jews from the city, re-naming it, Aelia Capitolina after himself(Publius Aelius Hadrianus). Moreover, Hadrian re-named the province, Syria Palaestina, in a derogatory reference to Israel’s ancient and wicked enemies, the Philistines( originating from Greek stock).

Yet it is important to remember that both the UN and the state of Israel were both founded on very similar principles: the exercise of democracy, liberty, national self-determination, as well as freedom from persecution and the respect for basic human rights. But the simple truth is that the vast majority of countries that oppose Israel respect none of these principles, as their actions so clearly demonstrate. Moreover, most of them don’t even care for an independent Palestine either. They just view Israel as a convenient scapegoat. It is tragically ironic that the UN, an organisation that has done so much good for the world, is siding with tyrannical regimes rather than a nation that clearly shares its own values!

This is especially prescient in light of what was witnessed by the world when Israel was condemned by most of the international community who accused them of genocide in the 11-day long war with the terrorist organisation, Hamas, which took place in May 2021. Despite the fact that Hamas initiated the conflict by firing rockets – a few thousand in all – into Israel from the Gaza Strip. The corrupt mainstream media fanned the flames of antisemitism by siding with the Palestinian terrorists, resulting in mass protests and wicked violence against Jews all over the world. Some of the participants in these protests included Biblically illiterate(read clueless), ‘nominal’ Christians. Furthermore, such events are prophesised to escalate as we get closer and closer to the triumphant return of Christ to the Earth.

The Bible also tells us that the people of Israel will not be uprooted again:

I will bring back the captives of My people Israel;
They shall build the waste cities and inhabit them;
They shall plant vineyards and drink wine from them;
They shall also make gardens and eat fruit from them.
 I will plant them in their land,
And no longer shall they be pulled up
From the land I have given them,”
Says the Lord your God.

Amos 9: 14-15

All of those prophecies have now been fulfilled.

Israel, a vibrant, liberal democracy, is here to stay no matter what evil intentions the goat nations plot against her. This is in spite of the majority of their people’s stubborn unbelief in the true Messiah they had rejected 2,000 years ago. That said, the Messianic Jewish population (who accept Yeshua as their Lord and Saviour) has increased ten-fold to ~30,000 in just a decade! Truth be told, Israel is actually one of the most secular nations on Earth, with Tel Aviv having risen to notoriety in recent years as the gay capital of Europe/Middle East. The Bible addresses the spiritual blindness of Israel in both the Old and New Testaments;

When Jesus had said these things, he departed and hid himself from them. Though he had done so many signs before them, they still did not believe in him, so that the word spoken by the prophet Isaiah might be fulfilled:

“Lord, who has believed what he heard from us,
    and to whom has the arm of the Lord been revealed?”

Therefore they could not believe. For again Isaiah said,

“He has blinded their eyes
    and hardened their heart,
lest they see with their eyes,
    and understand with their heart, and turn,
    and I would heal them.”

Isaiah said these things because he saw his glory and spoke of him.

                                                                                                                John 12:36-41

Jesus Christ ascended into heaven from the Mount of Olives in Jerusalem and the Bible tells us that He will once again set foot on it at His second coming, where He will fight against those nations wishing to destroy Israel:

Then the Lord will go forth and fight against those nations, as when He fights on a day of battle. In that day His feet will stand on the Mount of Olives, which is in front of Jerusalem on the east; and the Mount of Olives will be split in its middle from east to west by a very large valley, so that half of the mountain will move toward the north and the other half toward the south.

Zechariah 14:3-4

So, we’re living in exciting times; times that most unbelievers are completely oblivious to; but that too was foretold. Israel is indeed the timepiece for understanding the climactic events in world history.

So keep watching Israel, the Biblical ‘fig tree’ and pray for the peace of Jerusalem(Psalm 122:6), as we are instructed to.

A Form of Child Abuse.

If anyone causes one of these little ones—those who believe in me—to stumble, it would be better for them to have a large millstone hung around their neck and to be drowned in the depths of the sea.
                                                                                                                  Matthew 18:6

The immortal words of Jesus Christ attest to His great love and care for children. He warned us about the grave dangers of indoctrinating young minds to the ways of the world. Yet, our educational institutions, all the way from kindergarten through University, place a maximum emphasis on teaching children that all of the grandeur of the natural world can be explained by known natural laws and actively discourage children from entertaining thought processes that appeal to the supernatural or the divine. But these findings fly in the face of recent research conducted by psychologists that reveal something altogether different:- that young children, irrespective of whether they are brought up by parents in a religious or a secular home, are strongly disposed to thinking that many natural phenomena have been intentionally created by non-human agents or a deity of sorts and, furthermore, ascribe purpose to natural objects. Sadly, by the time children reach adolescent ages, much of this design intuition is suppressed by educational and/or cultural conditioning as they fully engage with our secular societies, teachers and parental influences(1)

Beginning in the late 1920s, the Swiss child psychologist, Jean Piaget, came to some very surprising conclusions about young minds. In particular, he showed that, contrary to popular belief, children are not merely less sophisticated thinkers than adults, they are capable of thinking in radically different ways to adults. In particular, Piaget described children as ‘artificialists,’ who drew their subjective intentional experience to conclude that all things were created by people or intelligent agencies for a purpose(2). As such, Piaget concluded, children are broadly inclined to view natural phenomena, whether living or non-living, in teleological terms. For example, clouds are for ‘raining’ and lions are for ‘keeping in a zoo.’ Furthermore, when Piaget asked children how natural objects originated, they frequently identified ‘God’ as the cause. And not only that, they perceived this God as anthropomorphic, having an overarching authority of its own, like some kind of ‘super parent’ and could even formulate a mental representation of such an agency despite its intangibility to the senses(2).

Intuitive Theists
Piaget’s assertion that young children were incapable of distinguishing between human and non-human causes proved controversial though, and subsequent studies have shown that he was wrong on some of these issues. Young children can, in fact, identify some natural causes. Yet he was correct in saying that children start out with the intuition that the natural world was made for a purpose. Back in 2004, University of Boston child psychologist, Deborah Kelemen, provided strong evidence that young children (4-7 years of age) are “intuitive theists” who are “disposed to view natural phenomena as resulting from non-human design(3).”

Further work conducted by Kathleen Corriveau, also based at Boston University, conducted a study of 66 kindergarten children aged between 5 and 6 years, from religious and non-religious backgrounds(4). In the study, the children were presented with 3 different narratives; religious, historical and fantastical. Across the board, children thought the historical narratives were true. When it came to the religious narratives though, children brought up in religious homes were more likely to accept it as true than their counterparts raised in secular homes. The most striking difference Corriveau et al found came from the presentation of the fantastical narrative, where 87 per cent of the secular kids rejected as false, as compared to only 40 per cent of kids raised in religious homes(4). That said, Corriveau concluded that “religious children have a broader conception of what can actually happen.” What is more, she added, “exposure to religious ideas has a powerful impact on children’s differentiation between reality and fiction.”

What I found most striking is how these child psychologists reacted to their own findings. For example, Kelemen suggested an ‘interventive’ learning program in a storybook format (where have we heard that before?!) to ‘help’ them develop greater ‘scientific literacy’ at an early stage(3). For Kelemen at least, the correct way to think is to uncritically believe in unguided evolution, where the encouragement of religious streams of thought are portrayed negatively, specifically as a form of indoctrination.

Born Believers
Building on these findings of the University of Boston psychologists, Justin L. Barrett, based at the Centre for Anthropology and Mind at the University of Oxford concluded in his recent book, Born Believers, that “children tend to believe that the world has order and purpose and that there is a supernatural element to the origin of this order(5).” Indeed, Barrett further added that, “a child’s playing field is tilted towards religious beliefs.” Furthermore, he raises a very provocative question- what if the indoctrination, as implied by Kelemen, involves teaching children not to believe in God? What if there are tangible benefits to not only nurturing but further developing the ‘intuitive theists’ within every child? In this capacity, Barrett further suggests that religious thinking enriches the imagination and is absolutely vital for contemplating reality itself. After all, even the most ardent materialist would be hard pushed to deny that every now and then, the unusual or even the ‘fantastical’ can and even does happen. Tacit examples include peer-reviewed, clinically documented medical miracles that defy any rational explanation(6). Furthermore, Roger Trigg, a collaborator with Barnett at the University of Oxford’s Ian Ramsey Centre added these comments to Barnett’s findings;

“This project suggests that religion is not just something for a peculiar few to do on Sundays instead of playing golf. We have gathered a body of evidence that suggests that religion is a common fact of human nature across different societies. This suggests that attempts to suppress religion are likely to be short-lived, as human thought seems to be rooted to religious concepts such as the existence of supernatural agents or gods, and the possibility of an afterlife or pre-life(7).”

Clash of Worldviews
These research findings made by psychologists are at direct odds with sentiments popularly expressed by atheists. For example, Richard Dawkins, who has adopted a hard-line stance on raising children with religion stated that we should be instilling in children a healthy degree of scepticism, teaching them that “‘it’s too statistically improbable for a prince to turn into a frog.” The irony has not gone unnoticed on me though, given the stupendous odds of life emerging from lifeless molecules and evolving into higher organisms. Francis Crick, co-discoverer of the three dimensional structure of the DNA double helix, also waded into the same argument when he reminded biologists that they “must constantly keep in mind that what they see was not designed, but rather evolved(8).”

Molecular biologist Douglas Axe at Biola University, in his excellent book, Undeniable; How Biology Confirms our Intuition that Life is Designed, wholeheartedly agrees that children are born believers in a designing intelligence at the heart of living systems but extends it further to include cognitive science. He writes:

“The children whose simple view of life has proved superior to the view endorsed by the Royal Society and the National Academy also have a simple view of consciousness. Their view begins to take shape in infancy, with games like peekaboo where small hands over small eyes form a screen that momentarily isolates the inside world from the outside world…..Through countless learning moments like this, children build a connection between their inside world and the outside world, a connection far more profound than anything technology has given us(9).”

For Axe, the overwhelming richness displayed to us by the outside world is thoroughly complemented by an equally rich inner experience, “almost as if the two were made to go together(9)” So what materialists like Dawkins and Crick are actually saying is that we should completely ignore what is, in reality, intuitively obvious. Axe continues:

“In our childhood, if not since, our design intuition assured us that life could only be the handiwork of God, or someone like him. As universal as this intuition is, though, it is almost universally opposed by the technical experts on life. None of us have been able to erase the intuition but many of us struggle to defend it against this professional opposition – or even to know whether it ought to be defended(9).”

What does all of this smack of? We are, in effect, being asked to believe our lying eyes. At least that’s the way Frank Turek, a leading Christian apologist, sees it. In his book, Stealing from God: Why Athiests Need God to Make their Case, Turek brings his readers’ attention to the mind-boggling complexity of the living cell, replete as they are with molecular machines far in advance of anything humans can currently build. He writes;

“Our brains are the instruments through which we have thoughts, but the thoughts themselves are immaterial products of your immaterial mind. And it is our minds that make us rational, conscious agents, with the ability to make choices(10).” So what does all this mean? According to Turek, “it means that you shouldn’t abandon your common sense intuitions for the nonsense ideology of materialism(10).”

Scientific Language to the Rescue
But Turek also alerts us to another aspect of the design intuition that even secular scientists, unconsciously or not, engage in. And it pertains to the language used to describe the incredible molecular machines operating at the nanoscale in living systems. These are such engineering marvels “that biologists can’t help but describe their parts with engineering names. There are molecular motors, switches, shuttles, tweezers, propellers, stators, bushings, rotors, driveshafts etc. And together they operate with unrivalled precision and efficiency(10).”

What Turek is driving at here is that, regardless of whether the scientists accept or reject design as a real phenomenon in nature, their language compels them to describe it as such. This important point went largely unnoticed until relatively recently, but some scientists have begun to sound the alarm bells. Professor Randolph M. Nesse based at the Center for Evolution and Medicine at Arizona State University had these words to say regarding the state of emotion research;

“….progress in emotions research has been slowed by tacit creationism. By tacit creationism I mean viewing organisms as if they are products of design, without attributing the design to a deity. Few scientists attribute the characteristics of organisms to a supernatural power, but many nonetheless view organisms as if they were designed machine(s(11).”

Nesse urges his readers to be more reflective about couching the language of emotion research in terms of Darwinian materialism, but seems unaware that this ideology is now being ditched by leading life scientists because it simply doesn’t work and has had its day in the sun(12). Seen in this light, Nesse’s arguments seem counterintuitive at worst and self-defeating at best. After all, if the language of design best describes the workings of the human mind or any other living system for that matter, and if it’s perfectly intelligible when couched in those terms, it seems downright silly to me to make active steps to changing it! Worst still for Nesse, by describing living systems in terms of designed artefacts, scientists have opened up a brave new world of biological research called biomimetics, which, as its name implies, seeks to model new engineering structures by mimicking the genius designs at the heart of living things. What’s more, it’s already achieved spectacular success. For example, by studying the antics of swarming honeybees, engineers arrived at novel solutions to designing telecommunications networks, and in studying the complex aerodynamic motions of dragonflies, produced remarkable refinements in drone design.

In a fascinating article by the Blyth Institute(13), author Annie Crawford argues that since teleological(that is, design and purpose in nature) language is so deeply embedded in centuries of biological enquiry, it simply cannot be abstracted away without either partial or complete loss of intelligibility to the audience it is intended to be presented to. Crawford goes further still:

“It is disingenuous,” she writes, “to continue pretending that teleology is or can be divorced from biology. Indeed, it is the teleological character of life which makes it a unique phenomenon requiring a unique discipline of study distinct from physics or chemistry(13).”

In summary then, the design intuition appears to be hardwired into the human psyche, and while it is actively suppressed in our secular educational systems from kindergarten through University, it cannot be entirely eradicated. St. Paul expressed these conclusions with astonishing accuracy in his letter to the Romans:

For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse.
Romans 1:20

What is more, human language reinforces this intuition, irrespective of whether or not we believe in creation or not. The more we learn about the world around us, the more it screams of design. And far from being a hindrance, the design intuition has proven to be spectacularly successful in cutting edge scientific and engineering research.

If it ain’t broke, why even begin to fix it?
