The Celestron Nature DX ED 8x42 is a mid-size roof prism binocular with 8x magnification and 42 mm objective lenses. It uses extra-low dispersion (ED) glass in the objective lenses, which virtually eliminates chromatic aberration, also known as color fringing. Images are sharp to the edges of the field of view, with true-to-life color. The difference is most noticeable in low light, such as at dawn or dusk.
The optics are fully multi-coated, so every air-to-glass surface has multiple anti-reflective layers. The prisms are BaK-4 glass with phase coatings. Together, these let more light reach the eye. Close focus is 6.5 feet, which suits viewing birds, butterflies and plants, as well as general use on the trail or at a stadium.
The housing is polycarbonate with a rubber armor covering. The binocular is fully waterproof and filled with dry nitrogen gas to prevent internal fogging of the lenses. Twist-up eyecups with multiple click stops work for eyeglass wearers and non-wearers alike. It can be mounted on a standard photographic tripod for extended viewing or digiscoping, using a tripod adapter that is sold separately.
