The Celestron Nature DX 10X42 ED Binoculars gets a major upgrade with the addition of ED objective lenses. Nature DX EDs optical performance rivals that of more expensive binoculars, at a price to fit your budget.
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.
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. Celestrons 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.
