Bresser NightExplorer 15x70 Waterproof Binoculars with Tripod and Backpack Included

These rugged, waterproof astronomy binoculars offer powerful light-gathering performance and 15x magnification, even in bad weather. The extra-large 70 mm objective lenses let plenty of light into the binoculars, while the 15x magnification delivers highly detailed views of the objects you observe. Stray light is also kept to a minimum, so you can enjoy a clear view and the best possible optical images. At a distance of 1,000 metres, the field of view is 77 metres wide. The highly corrected eyepieces, with 5 lenses in 3 groups, produce bright images with sharp edges. The premium BaK-4 optics (barium crown glass) feature fully multi-coated lenses to increase light transmission and reduce reflections.
