Cometron 7x50 Astronomy Binoculars – Entry-Level for Stargazing and Comet Watching – Large 50mm Objective Lenses – Wide 6.6° Field of View – Multi-Coated Optics

These binoculars are very capable night sky viewers. They replaced my Russian-made Sotem 7X50s that were stolen. The Sotem's were quite good, but with the current world situation, very difficult to replace. Having read up on the Celstron units, I figured I would give them a try. The first pair I received were returned due to a hair in the view field of the right lens. I was disappointed about the quality control, as these are manufactured in China. The second pair had no issues and they are great for night sky viewing with stars shown as points, good views of nebula, and star clusters. A good product for a bargain price.

7x50 is the sweet spot for binoculars intended mainly for stargazing. 7x magnification is enough to resolve a lot of double stars, give you easy views of Jupiter's 4 largest moons, to see the major features of our own moon, and (with solar filters) to see sunspots. Anything less and you might not see enough detail to feel satisfied, anything more and you're going to have a hard time holding the binoculars steady enough to enjoy the detail being provided by the magnification. 50mm objective lenses bring in enough light to allow you to get truly grand views of the milky way (if you can get to a dark sky location) and clear resolution of images; of course larger is better but also a lot more expensive and often manufacturers pair the larger objectives with higher magnification which is NOT helpful. The specific optics of these Celestron "Cometron" binoculars have a good field of view so they're great on nights with peak meteor activity or for looking at wide swaths of sky at one time for other reasons. The quality of the optics is quite good with little aberration, decently dark backgrounds, and the two elements are well collimated – very important and not always the case for inexpensive binoculars. For the price these are hard to beat. I bought a pair of Meade binoculars also and while they were pretty good the two optical paths were not collimated at all; which means it was almost impossible to "merge" the two images because the two optical arrays weren't parallel to each other and therefore weren't pointing in exactly the same direction. They're OK for casual terrestrial viewing or as toys for kids but otherwise worthless. These Celestron models, only slightly more expensive, are not only a fantastic value they are among the best low-end hand-held binoculars available, you'd have to pay a hundred dollars more for a significant increase in quality. This isn't a knock on Meade in general, they make great scopes, but the low-end binoculars I've bought from them have some quality-control issues and aren't in any special way better than these Celestron binoculars. These binoculars are easily adjusted for people with different pupillary distance (spacing between the eyes) by just squeezing the scopes together or pulling them apart around the central hinge. Focus is done with a center adjuster and is smooth in both directions. There is a diopter adjustment on one eyepiece (allowing the user to fine-tune the focus should their eyes require different correction). The eyepieces have foldable eyecups so they're easy to use with or without eyeglasses – note that unless you have significant astigmatism it is better to use a telescope or binoculars without your glasses.

I bought these for both terrestrial and sky use. I would say that the quality is pretty good overall and great for the price. Optics is something that has a very steep price to quality curve and these seems to be good enough for the amateur (no noticeable chromatic aberration that causes small bright white objects to smear into a rainbow of colors as in poor quality binoculars). In reading the reviews, I noticed some people are unfamiliar with using binoculars. Binoculars are hinged in the middle to allow you to adjust the span between the two lenses to merge the two images into one image. At night look at the moon or a distant street lamp which is a single object (as opposed to a star field) and adjust the hinge as you look to merge the images to create one distinct image. Each person will have a slightly different adjustment for this. Then once you have set this you can look at the stars. The other adjustment is to close your right eye and focus on some distant object using the main focus adjustment in the center. Then open your right eye and adjust the individual diopter adjustment to focus the right eye's image. Each person will have a different setting for this that depends on their eyes. Also note that hand held binoculars are not a replacement for a telescope on a tripod. It is impossible to hold the binoculars by hand steady enough to prevent shaking of the image even at relatively low magnifications, though if you can rest your elbows on something firm that helps. On the other hand, binoculars like these are far easier to carry with you than a telescope. The good: The optical quality is pretty good and I would say very good for the price point. They are reasonably light while still giving a good image. Great for looking at the moon and terrestrial use. Could use improvement: If as the result of lasik or cataract surgery you have "mono vision" where one eye is focused on distance and one eye is focused for reading and close-up, the range of the individual eye diopter adjustment on the binoculars is right up against the limit the diopter adjustment on the binoculars will go. It would be better if there were more range of the binocular diopter adjustment.

I love these binoculars and for the price that I paid for them you wouldn't believe how thick and sturdy and heavy these binocular are but in a good way and you can show very close everything I took them out for the blood moon and that was so cool if you like stars and astrology you will love his binoculars!!! I live in the city even the Stars that are hiding behind the clouds and they peek through you can see the stars cuz he's a very good binoculars!

Just an amateur stargazer looking for something convenient and simple to use that's easy on the wallet. This hits the mark, and lets me see with far more clarity than the horrible pocket binoculars I was using. It gathers just enough light and limits shake to give me a nice evening wondering under dark skies.

I bought these to supplement my stargazing. I am new to the hobby and have been using a bigger brother of these little guys (the 15x70), but while having to order another pair of the giants due to an accident, I decided to toss in a pair of these as well. They are so CHEAP! And so highly rated! I figured for the price it would be hard to go wrong. And this was the case - things went extremely right. I went to an event our local astronomy club gave for a scout group and set up my 15x70 on its tripod, and hung these around my neck. A little more background: we are in Florida, and the event happened in mid-June, and it had stormed all afternoon and was still dripping when we arrived at the site. The skies partially cleared as we waited, but the humidity could have filled up a filter jug. About 1/4 of the way into our various demonstrations, my large binoculars got fogged up on their tripod. The sides of the big binos - which are not coated with rubber - were literally dripping with dew by the end of the demonstration. The lenses fogged up completely, rendered useless by Florida's humidity. I could see more with my naked eye. So much for my brand-new pair of 15x70 giant binocs. It was a much happier story for our little troopers here. They have rubber on almost all of the exposed parts, and I don't know if that was the reason, but never ONCE did I notice fogging on the lenses, nor any dew on the binos. Thus it was that I was able to impress the scouts with how a light, inexpensive pair of binoculars can help open up the sky. I've heard stories of collimation problems, but I'm happy to say my pair was aligned perfectly and performed wonderfully, and one excited scout is almost certain to get a pair of them for Christmas this year as a result of the event... Of course, these would in theory be outstripped in functionality by much more expensive and/or larger binoculars. They don't image-stabilize, they aren't waterproof, and they are probably more subject to quality-control issues than if you bought something for $300 or more. But... price. You could buy TEN of these for the price of the really good binocs, and have spares for parties. They won't open up the sky like the larger binoculars or a telescope, but... they still bring out details the naked eye cannot see, and are the first thing I'd grab if I only had limited stargazing availability because they are zero-to-viewing in just a few seconds. And apparently they are somewhat resistant to the effects of extreme humidity, which is a massive plus here in the semi-tropics. Also, as a bonus, their smaller size makes them useful for daytime viewing as well (nature hikes, concerts, etc), something that I cannot say about the heavy, bulky 15x70s. These will start accompanying me on my park walks, and I've already used them to observe deer in my yard. I therefore highly recommend these not only as starter binocs for newbies to the night sky world, but as a permanent supplement for those who have a larger telescope. And they'd be great for daytime users as well. Their portability, usable quality, ease-of-use, and humidity resistance really makes them stand out when you consider how little they cost. And as I found out last night, they are just light enough that many children can manage them for several minutes at a time (though if the kid is small enough you might want to invest in a light-weight tripod - something that costs less than $30 should be fine for this particular pair). Yes, the really expensive brands are no doubt better, but at less than $30USD per pair, it's easy to justify starting out with these or just adding a pair to one's scope collection.

K got these for my dad for Christmas and he is extremely happy. He had a very old pair of Bushnell (like 40 years old) that he would use on occasion to look at deer or an eagle since we live in the country. His Bushnell still worked but he wanted a pair to keep out in his shop, well these now stay beside his recliner in the living room :) I seen these and figured they would be just ok for what he wanted and the price was great since I couldn't afford a new pair of bushnells. I thought they would be of cheaper quality, but i hoped was wrong and I was. These are much sturdier and sound then I expected, they feel very solid. They are lighter in weight so your arms don't tire, which is nice. Things are crisp and clear when viewing them even at a distance (about 3 or 4 telephone polls, here in the country thats about 600 to 1000 feet) Very easy to focus also. Another awesome thing is the clarity in lower light. Deer like to come out at dusk and we can see them pretty good (I don't mean these work in the dark, but when the sun has about set and the worlds light is a yellowish gray, these work well). We just had a super moon and seeing it through these binoculars was absolutely breathtaking. I could really make out the markings on the moon. My dad was even wowed! I plan on grabbing another pair of these since he has forgotten his old pair and only uses these. I really do recommend these to anyone who wants a nice binocular. These are NOT cheaply made and I have no doubt you will be happy with this purchase. I gave it 5 stars because my dad and I are really truly impressed with Celestrons. I don't have anything negative to say! For once I got much much more then what I paid for, in a very good way! Thank you so much!

I've been observing the night sky with binoculars and telescopes for 30 or so years, and I've tried to frugal about my equipment purchases, so I understand the budget-minded astronomer. I totally get that. I'll start with the positives. These binoculars are lightweight, easy to hold, come with a nice wide strap, soft carrying case, plus they have firm interpupillary distance adjustment, stiff center focus knob that will not move when you press your eyes against the eyepieces, and importantly, a diopter adjustment for the right eye. To be honest, for the $35 I spent on these in May 2020 (may be different when you buy these), that was more than I expected. There are four caps to cover the eyepieces and objects lenses. There is even a 1/4-20 thread at the central portion so you can attach these to a binocular bracket and a tripod. Honestly, all of that is REALLY nice for the price paid. Can't complain about that at all. When looking at objects, the view was - well, I guess for the price pad, it was not bad. Not great, but not bad either. I have seen much worse. The set I purchased were collimated (meaning both sides of the binoculars are parallel, so the images "merge" at your eyes and don't cause eye strain trying to make them line up). The star images in the central 50% to 60% of the field of view were pretty sharp. Not quite pinpoint, but again, for the price paid, better than I expected. In short, could I see more stars than I could naked eye? You bet. But this is where the lower cost becomes obvious. I compared these to a $100 set of binoculars I own. Exact same specs - 7x50's, and I compared them on the same night, side by side, on the same objects. Keep in mind, a $100 set of binoculars is not all that expensive. Even they are considered rather average in cost and specifications. I own both better and worse binoculars - so these are good "middle ground" to test against. Yet in those, I could see more. A LOT more. For one, in the "better" binoculars, the stars were not only more pinpoint in the center, they were pinpoints all the way out to the edge. In the Celestron... not so much. They began to get less pin-point-like outside of 50%, and by the outer 15% to 20% of the field, they were quite distorted - like seagull shapes. So brighter stars are visible there, but are not as clear. And dimmer stars just get smeared out of existence, until you move them into the central area. So you lose some effective field of view because the stars simply become "not" stars anymore. This is less than ideal for things binoculars should excel at for astronomy: Sweeping the Milky Way, looking at large clusters, or see more of the sky than a telescope can show you. Even worse if you're looking for galaxies, as very "seagull star" looks like a galaxy at the edge, until you realize, "No, that's not a galaxy - it was a smeared star." And another issue: Fewer stars visible. I aimed mine north towards light polluted Chicago, at the two stars that frame M57, the Ring Nebula. I could not see the nebula in either set of binoculars, my "good" pair" or this one. But there are many stars in that area, due to it being just off the edge of the galactic plane. In my "good" 7x50's, I counted 19 stars visible. In the Cometron, just 14. In another test looking at the area of Pollux and Castor, I got a similar result. These means the Cometrons lost about 1/2 a magnitude of stars. If the idea is to see more stars with binoculars, not seeing another 25% you COULD see just by having a little bit better binoculars means you may miss a lot, especially in light polluted areas. That's why I aimed mine towards light pollution, to see what the effect would be. That's a lot of stars you either could see, or miss out on. You'll have to answer whether that matters to you or not - I get it, it's about a price point too. I am fairly confident the fewer visible stars was because the dimmer stars aren't even visible, as there are fewer anti-reflection coatings on the Cometrons, so dimmer stars get "bounced off" the glass and never make it to your eyes. 1/2 a magnitude may not seem like a lot, but the difference between seeing all stars down to 7th magnitude stars (26,533) versus 6th magnitude (8,768) is a HUGE number. Even taking half of that difference to account for it being a half a magnitude - that's potentially 8,882 stars you will NOT see. That's a lot of stars you'll miss. And those are potentially observable, in light polluted areas. But the Cometron's will keep you from seeing them. And lastly, I think the prisms in this set of optics are smaller than they should be. There is something odd about how I had to hold them to get a good image. In most binoculars, I can hold the specs up to my eye and see the whole field. In these, I sometimes had to hold the binocular further AWAY, otherwise there was this "kidney-beaning" effect there the outer edge would just be black. It was rather difficult to hold them just-right to get a good image. Perhaps that might work okay for eyeglasses wearers, because the eye relief is further back. For me it was a bit difficult to use. Conclusion: If you have a VERY small budget for binoculars, these are minimally adequate. They will focus okay, but not perfectly. And they will show you more than you can see naked eye, for sure - several magnitudes fainter than naked eye, to be sure. But you will still see less than you could see in the same size, if slightly better, binoculars. And they have some pretty significant aberrations, which should not be discounted. It would be money well spent for better ones if you are able to afford it - the greater light throughput will show you more stars, and the better focus both in the center and especially at the edges will give you a far better overall view of the heavens. I have looked through worse binoculars, so I don't say "Do not buy these." Because they will indeed improve on what you can see naked eye. But it could be better.

We love our pair of these. Will be getting a longer range pair eventually too. Good quality.

The focusser is all-plastic and thereby whobbles a lot. The lenses immediately fog up when using the lens cups. The image does not appear to be very sharp.

Ürün belirtilen tarih aralığında geldi, korunaklı bir şekilde paketlenmiş, satıcıya teşekkür ederim. Henüz mercek ayarlarını tam olarak yapamadım ilk defa dürbün kullanıyorum, ama bu haliyle bile çok beğendim, balkondan çok uzak mesafeleri bile yakın ve net gördüm. Fiyat performans açısından başarılı bir ürün. Tek moralimi bozan ürün bugün elime ulaştı ve bugün fiyatının 400 TL birden düştüğünü görüyorum, açıkçası hoş bir durum olmadı bu.

Top, achetées en promo à super prix, ce sont mes premières « vraies » jumelles après avoir eu des modèles vraiment bas de gamme. Je suis impressionné par la luminosité et la netteté.

Vamos lá, ele chegou no período de 13 dias (normal) entregue pela total express 💯. Paguei 401 Sobre o binóculos, é o meu primeiro, e pra ser bem sincero eu amei! Depois que peguei a prática de regular e fazer as observações, foi fantástico, a qualidade é muito boa, pena que na foto não dá pra ver direito mais é bem limpo, ainda não tiver a oportunidade de fazer observações noturna pois tá nublado mais pelas observação acredito que vai dá bom. Sobre a aproximação de 7x, não aproxima tanto mas tem uma ótima e muito boa aproximação, em lugares de médias distância fica ótimo, não há do que reclamar. Por mais que algumas pessoas falaram que é frágil, no pegar dele passa uma certa resistência, é bom de pegar nele, além de ser muito bonito. Sobre os acabamentos, olhando inversamente, do lado maior para o menor, da pra perceber tipo uma cola em ambos os lados, não sei se é normal ou é a qualidade do acabamento, porém não atrapalha, só questão de estética mesmo. Recomendo sim, pode comprar sem medo, gostei demais👌💯
