    Minimally adequate for astronomy - here's why

    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.

    Great wide field of view for hand held star gazing, good general purpose binocs as well

    These binoculars are great for hand held night sky viewing, the 50mm objective lenses allow plenty of light to be collected and combined with the 7X provide a wide field of view. The magnification may seem a bit underwhelming, but I've found that while my 10x50 produce a lot of hand held jitter when trying to view the night sky, these 7x50 provide reasonable magnification while making it much easier to obtain a stable image. If you want to use a more powerful pair of binoculars for astronomy, you really would want a tripod mounted setup.The moon doesn't fill much more than a quarter of the view, but the details are nice and sharp. You certainly see a lot more stars than you can see with the naked eye. The wider field of view makes it much easier to find the stars that make up a particular constellation with out getting lost, which make these perfect for getting to know the night sky. I also find this to be excellent for satellite viewing. Combined with an smartphone app like Heavens Above, you can spot a number of satellites scheduled to pass over your location post dusk and pre dawn. I found it much easier to track satellites using these 7x50 binoculars vs. my 10x50 pair. Whether shifting from naked eye viewing of brighter satellites, or using the binoculars to spot satellites your naked eye would miss, it's just much easier to find your target with the wider field of view these binoculars offer.The specs don't suggest many bells and whistles, which had me a bit worried about fogging issues on a cold night, but as long as I let these adjust to the ambient temps first, I have experienced zero issues with fogging.Overall, I think these are a great value for the dollar for night sky viewers. Any greater magnification and you'd want to go with a unit paired with a tripod, which is a bit limiting if much of your viewing is nearer the zenith than the horizon. Or, probably much better, just buy a telescope. If you are just going to sit or lay out at night and do some stargazing, these are perfect. I can also see my self using these as an adjunct to a proper telescope.Edit: I just noticed tonight that without my glasses, I can't focus these sufficiently to correct for my vision. I am very near sighted, but these are the only binoculars I have ever used that I couldn't focus for my vision. -1 star for that limitation.

    My Favorite Binoculars

    A fantastic pair of astronomy binoculars. Light enough that they don't need a tripod, good solid construction, extremely convenient and portable. I use them all the time, and I'm rarely disappointed. Good enough to glimpse Andromeda from my light-polluted front yard, and they treat you to lovely views of the Orion Nebula, Pleiades, Hyades, and plenty of other Clusters. Highly recommended to anyone who wants a nice pair of astronomy binoculars that you'll use regularly, and you can't beat this price anywhere. I also own the Celestron 15X70 pair, and while those are even more stunning, they're just not convenient because they're bulky, and too heavy to hold without a tripod. I find myself using these far more often.If I could give this pair 6 stars, I would.

    Light and portable, great for astronomy especially as a beginners

    Bought for use in astronomy. I wanted something portable that I can easily carry around with me. I’m really happy about the field of view they offer. Great if you’re a beginner, or if you just want an easy transportable point and go set-up.I had a lovely view of Venus in Pleiades in April, and you can see Jupiter’s moons. Our moon also looks beautiful.It really depends what you are looking for. If you want to zoom in and see details such as banding on planets, a telescope would be a better purchase. If you just want to see some lovely views of celestial objects, or find your way round the constellations, they are really perfect. Even in light polluted London, there are so many stars to see that you miss with the naked eye.They are really well made and sturdy, and I’m super happy. Just bought a tripod to go with them for added adventures!

    More than expected

    I had a celestron telescope many years ago which had to sell because of back problems.So I now decided to get the binoculars for stargazing sitting on a reclining chair.One word says it all: Fantastic!!

    Good value for money

    They work well enough but don't focus beyond infinity so short sighted people still need glasses, this is made clear in the guide. Perfect for stargazing though.

    An affordable entry to a new hobby

    Celestron Cometron 7x50 is a good option for people who want to get started on star gazing with minimum cost and equipment. It does not compromise on build quality, optics, and coating as far as the casual observer can make out. It is light enough to be held in the hands without much shaking. More importantly, it is handy enough to grab casually whenever you fancy, so it has less chance of gathering dust in an almirah. It allows you to see a number of stars normally hidden by too much ambient light in cities. The large objective lens is unique among binoculars of this size and price range.Before buying, it is necessary to adjust ones expectations: it will not show you Saturn's rings. Stars and planets are visible as dots of light. It is meant to see more stars - not more detail. Planets being closer, do show some fuzziness and trails - this set is not meant to have perfect optics of the more expensive binoculars. One must be prepared to make an effort to collimate to adjust both eyes properly. It has good enough resolution to watch terrestrial features, but for something like bird-watching a higher magnification might be useful. The Celestron upClose series might help.To conclude, it is a great start to learn how to navigate the night sky. Once you can identify most of the major objects and orient yourself without needing an app, then might be the time to go for something more expensive.
