Celestron’s Nature DX binoculars get a major upgrade with the addition of ED objective lenses. Celestron’s ED glass delivers visibly brighter, sharper images compared to non-ED binoculars. The difference is especially noticeable in low light conditions, such as at dawn or dusk. Nature DX ED features fully multi-coated optics. The Nature DX ED is a birdwatching binocular. Its fully multi-coated optics and BaK-4 prisms will maximise light transmission, resulting in bright, detailed images, and the ED objective lenses will further enhance these features, especially in dim light conditions. ED glass also helps you spot insects and plants at a close focus of just 6.5 feet. These binoculars are suitable for eyeglass wearers and non-eyeglass wearers and include a protective padded nylon case for easy storage and portability.
