Celestron 71198 Cometron 7x50 Porro Prism Binoculars, Black

Great Nocks! Crater's on the Moon are very vivid! Glad I treat myself...

I have previously owned a set of Celestron 25x70 Astromaster binoculars which were pretty good but they were impossible to use handheld due to the 25x magnification. They were also a bit prone to falling out of collimation. These 12x Cometrons are much more like the thing. At 12x, they are easy to use handheld and produce some excellent views of astronomical targets like the Andromeda galaxy, Milky Way, the Pleiades and other objects that I couldn't fit into the 25x's rather restricted field of view. They are well made and the only slight criticism that I have is that the rubber eyecups are deformed very easily. It's not a problem in practice but it takes away a little from the otherwise excellent standard of construction. All in all, they are a much better proposition than the 15x or 25x Astromasters. A lot more practical and great for viewing those deep space objects.

I m a newbie into astronomy and I wanted to start observing the sky and get to know basic constellations and areas to look. I love them for a beginner and also can be used for bird watching and pretty match anything else you like. They are good quality and lightweight.

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!

I've had other benoculars in the past but I find these to bring a great combination of low power, good field of view, and good aperture for the size. They work really well for spotting objects like the Pleiades and Orion's nebula. I was even able to resolve two of Jupiter's moons. Very hard to beat for the price. An excellent tool for getting started with amateur astronomy.

Really great pair of binoculars for the price

Took them on a walk and saw lots of birds, still trying to get to grips with them at night, though... maybe I'm a better bird watcher than star gazer!

They work well enough, if you are lucky and don't get a pair that need aligning, but they don't focus beyond infinity so short sighted people still need glasses, this is made clear in the guide. Ok for stargazing though, but to be honest you get what you pay for. I obtained better quality though an old pair of 8x30 Carl Zeiss Jena from the 80's than these. If you can afford it go for Nikon or Olympus.

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.

Très satisfait de leur qualité pour une paire de jumelles à moins de 80 € ! J'étais plutôt à la recherche d'une bonne paire de jumelles utilisée principalement pour l'astronomie, mais aussi pour l'observation de la nature. Et je ne suis pas déçu ! Certes, elle n'est pas légère... Mais je m'attendais à pire ! Habitant la campagne, j'ai la chance de pouvoir observer une faune diverse et variée depuis ma maison, et je ne manque aucune occasion de sortir ces jumelles pour observer la nature quelques instants. Pour l'observation prolongée, j'utilise un trépied. Pour l'observation du ciel étoilé, je m'installe confortablement sur ma terrasse, dans un fauteuil multiposition, et là, je profite pleinement de ses objectifs de 70 mm, qui lui confèrent une bonne luminosité pour un grossissement raisonnable de 12X. Le grand diamètre des oculaires me permet de conserver mes lunettes pendant l'observation. Pour le prix, je ne regrette vraiment pas mon achat...

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

Hatte versehentlich zwei Cometrons bestellt, eins bei Lidl und eins bei Amazon. Also eins verschenkt - Begeisterung beiderseits! Mit der 70er Öffnung ist das Teil recht hell und lässt sich dank der nur 12fachen Vergösserung am Tag grade noch freihändig nutzen. Die Austrittspupille ist angenehm gross. Für längeres Gucken braucht es alledings schon kräftige Arme oder ein Einbein-Stativ. Sterne betrachten ohne Stativ - da muss ich passen. Wg. des graden Einblicks ist das Sterne Gucken allerdings selbst mit Stativ manchmal beschwerlich. Das Bild ist aus meiner Sicht völlig OK. Natürlich hätte ich auch lieber ein Fujinon - wer nicht... Das Seeing: Lebte ich irgendwo weitweg auf dem Land, so würde ich lange auf ein Fujinon sparen. Leider wohne ich in der Nähe einer Grossstadt. Durch den Lichtmüll ist das Seeing Mist. Selbst die teuerste Optik hilft da wenig. Da kommt mir dieses Glas grade recht. Preiswert, brauchbar, und viel Geld gespart für einen Urlaub wo man richtig Sterne sieht. Grüsse

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.
