The Celestron Nature DX ED 10x42 Binoculars:
Now with ED objective lenses, the Nature DX EDs optical performance is high-quality. This versatile, all-around binocular is a great choice for the trail, the stadium, the arena, or just about anywhere you want a close-up view of the action without sacrificing brightness or detail. It's an especially great companion for nature observation and bird watching, with ED glass that helps you spot the subtlest field markings and a close focus of just 6.5-feet.
ED Objective Lenses
Extra-Low Dispersion (ED) glass virtually eliminates chromatic aberration, also known as color fringing, a visual defect common 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 outstanding, true-to-life color.// Not all ED glass is created equal. Celestron's high quality ED glass delivers visibly brighter, sharper images compared to non-ED binoculars. The difference is especially apparent 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-to-glass surfaces are coated with multiple layers of anti-reflectivity 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 internal faces and passes through to the eye.
Taken together, the fully multi-coated lenses and BaK-4 prisms maximize light transmission for the remarkably bright, highly detailed images. The ED objective lenses further enhance these features, especially in low light conditions.
A durable rubber armored, polycarbonate housing protects your Nature DX ED binoculars from damage without weighing you down. Viewing through Nature DX ED is comfortable for both eyeglass wearers and non-eyeglass wearers, thanks to the durable twist-up eyecups. Twist through multiple click stops to find the position that works best for you. Also, the binocular is fully waterproof and filled with dry nitrogen gas to prevent internal fogging of lenses. Nature DX ED can stand up to even the toughest outdoor conditions.
Carry your Nature ED on the comfortable included strap. The binocular also includes a protective padded nylon case and lens caps for storage and transport.
Perfect for a Variety of Uses
Nature DX ED 10x42 features a close focus of just 6.5-feet, making it perfect for viewing birds, butterflies, plants, or other nearby subjects. For distance viewing, the 10 x 42 model offers a wide field of view so you can easily follow subjects as they move with less need to move the binoculars.
Ways to Observe
It's also tripod-adaptable, so you can mount it on any standard photographic tripod for extended viewing or digiscoping (digital photography through the eyepiece- a.k.a. afocal photography). The tripod adapter, tripod, and smartphone adapter are all sold separately.
