The prisms inside Nature DX ED are made of high-quality BaK-4 glass with phase coatings applied so that more light is reflected off their internal faces and passes through to the eye.

The apparent angle of view approaches wide angle to not only present an immersive observational experience to complement the impressive performance, it also helps to minimize the appearance of the distracting hand shake that is common when holding high-power optics.The angle of view is generous and despite the powerful magnification, these binoculars can focus as close as 8. Armed with 12x magnification and 50mm objective lenses, the Celestron Nature DX ED 12x50 have a slightly higher magnification than most binoculars designed for all-round use, so they’re best considered if you want close-up views of distant subjects. Taken together, the fully multi-coated lenses and BaK-4 prisms maximize light transmission for the remarkably bright, highly detailed images. In an all-round impressive package, what the Celestron Nature DX ED 12x50 lacks is eye relief; at just 14. Something we found slightly annoying was the objective lens caps, which are attached to the tubes and hang down while you use the Celestron Nature DX ED 12x50.

However, in practice the Celestron Nature DX ED 12x50 performs really well at night, with the Andromeda galaxy looking sharp and well defined. Ditto the crescent Moon, which looked clean with no sign of purplish fringing – thanks to that ED glass. The eyecups are attached to the neck strap, which is of decent quality, like the padded case with the Nature DX ED 12x50. degree field of view constitutes an incredible close-up when viewing objects in the distance, with a trip to see some motor racing heralding bright and sharp views even in the distance.While primarily ideal for bringing distant objects closer, these binoculars can focus sharply on objects just 2m/6. The considerable extra outlay gets you much better optics than you will find at the entry-level, that's always the case with binoculars. From the SkyProdigy, a telescope so smart it can align itself, to our high-performance EdgeHD optical system, we’ve revolutionized the hobby of astronomy for beginners and advanced amateurs alike.

The 50mm objective lenses are large enough to gather lots of light, while still being lightweight enough to use without a tripod. What’s more, the binocular is fully waterproof and filled with dry nitrogen gas to prevent the internal fogging of lenses.

We found operating the Nature DX ED 12x50 easy, with the diopter adjustment and center focus wheels feeling exceptionally smooth but with enough resistance to stop any accidents knocking them out of focus. What’s more, the binocular is fully waterproof and filled with dry nitrogen gas to prevent internal fogging of the lenses.
