Good Quality

Good product. Received as specified. Performance as mentioned.

I bought this binocular, is a wonderful result

very nice.

I brought it five days a go it's a good product I recommend it 😊

Its good to watch distant land or the moon but beyond that the vision is not clear when full zoomed

Very basic

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.

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.
