The award-winning Nature DX binocular from Celestron gets a major upgrade with the addition of ED objective lenses. Nature DX ED's optical performance rivals that of more expensive binoculars, at a price that fits your budget.
This versatile, all-around binocular is an excellent choice for the trail, stadium, arena, or just about anywhere you want a close-up view of the action without sacrificing brightness or detail. It's an especially excellent companion for nature viewing and bird watching, with ED glass that helps you detect the subtlest field marks and a close focus of only 6.5 feet.
ED objective lenses
Extra-low dispersion (ED) glass virtually eliminates chromatic aberration, also known as color fringing, a common visual defect in binoculars. Nature DX ED delivers razor-sharp images, even at the edges of the field of view. ED glass is also known for producing images with exceptional, true-to-life color.
Not all ED glass is the same. High-quality ED glass from Celestron offers visibly brighter and sharper images compared to non-ED binoculars. The difference is especially evident in low light conditions, such as at dawn or dusk.
Coatings and prisms
Nature DX ED features fully multi-coated optics. A binocular can be considered "fully multi-coated" when all air-glass surfaces are coated with multiple layers of anti-reflective coatings so that the maximum amount of light passes through the glass to the eye.
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 inner faces and passes to the eye.
Together, the fully multi-coated lenses and BaK-4 prisms maximize light transmission for extraordinarily bright and highly detailed images. ED objective lenses further enhance these characteristics, especially in low light conditions.
The body
A durable rubber armored polycarbonate housing protects your Nature DX ED binoculars from damage without overloading it. Seeing through Nature DX ED is comfortable for both eyeglass wearers and non-eyeglass wearers, thanks to the durable rotating eyecups. Rotate through multiple click stops to find the position that best suits your needs. In addition, the binocular is completely waterproof and filled with dry nitrogen gas to prevent internal lens fogging. Nature DX ED can withstand even the harshest outdoor conditions.
Perfect for a variety of uses
The Nature DX ED 10x42mm model offers 10x magnification, perfect for close-up views of distant subjects. Despite its higher magnification, Nature DX ED 10x42 maintains a close focus of only 6.5 feet, making it ideal for viewing birds, butterflies, plants and more.
Ways to Observe
Carry your Nature ED on the included comfortable strap. It's also tripod adaptable, so you can mount it on any standard photographic tripod for extended viewing or digiscoping (photography through the eyepiece). The tripod adapter is sold separately. The binocular also includes a padded nylon protective case for storage and transport.
