Celestron – SkyMaster 18-40x80 Zoom Binocular – 18 to 40x80mm Zoom Eyepiece – Multi-Coated BaK4 Optics for Outdoor and Astronomy Viewing – Tripod Adaptable – Includes Soft Carrying Case

Celestron SkyMaster 18-40x80mm binoculars are ideal for amateur astronomers or anyone who observes at great distances. The large 80mm objective lenses have excellent light-gathering capabilities, delivering superior low-light performance, even in the dimmest conditions. With SkyMaster’s 18x-40x zoom magnification, you can find your subject at lower magnification (18x) then zoom in for a close-up view (40x). Moreover, the prisms inside the binocular are made of high-quality BaK-4 glass so that more light is reflected off their internal faces and passes through to the eye. The multi-coated lenses and BaK-4 prisms maximize light transmission for remarkably bright, highly detailed images. The binocular's durable exterior housing protects from damage without weighing you down. Viewing through the SkyMaster binoculars is comfortable for eyeglass and non-eyeglass wearers, thanks to the foldable rubber eyecup. The SkyMaster binocular is tripod-adaptable, so you can use a binocular tripod adapter (not included) to mount it on any standard photographic tripod or monopod for extended viewing or digiscoping (photography through the eyepiece).
