View the natural world up close with the COSMOS Tree of Life 10x42 Binocular by Celestron, the perfect companion for your next outdoor odyssey. Designed for optimum views of wildlife and landscapes, Tree of Life Binoculars feature phase-coated BaK-4 prisms and fully multi-coated optics for great image detail.
High quality BaK-4 prisms are phase coated to increase contrast and resolution. Fully multi-coated optics provide maximum light transmission through the entire optical path, for brighter images, even in low light conditions.
The full-size 10x42 model is a great step up into the world of serious binoculars. You'll get high magnification for a closer view of your subject, especially if you are observing it from a distance. The 42 mm objective lenses are a popular choice since they are large enough to gather more light than compact binoculars, but are still light enough to comfortably handhold for longer observing sessions.
Binoculars that fit your lifestyle
Waterproof, fogproof, and nitrogen purged, these binoculars can withstand the elements. A durable rubber armored, polycarbonate housing protects your Tree of Life Binocular from damage without weighing you down. Twist-up eyecups with multiple stops ensure proper positioning of the eyes, even for eyeglass wearers.
Inspired by COSMOS: A SpaceTime Odyssey
Airing this spring on FOX and National Geographic Channel, COSMOS: A SpaceTime Odyssey explores how each one of us is connected to nature and the Tree of Life. In that same spirit, Celestron engineers designed the COSMOS Tree of Life Binocular as the ideal tool for observing the natural world. Tree of Life's unique rubber armor in light desert sand offers a distinctive look, and the Tree of Life adorns the focus knob.
