Celestron Nature DX ED Binoculars
Celestron Nature DX ED binoculars add Extra-low Dispersion (ED) glass to the 8x42, 10x42, 10x50 and 12x50 models. As with the original Nature DX binoculars, they have phase-corrected prisms, are fully multi-coated, waterproof and nitrogen purged, and have a rubber armored polycarbonate body. They retain the close focus, field of view, and other specs of the original Nature DX binoculars.
