The 10x42 Cosmos Tree of Life Binocular from Celestron features a fully multicoated optics and a weather-sealed housing. Celestron equips Cosmos series binoculars with a fully multicoated optical path that uses BAK4 prism glass with phase-correction coating to render enhanced clarity and image brightness. A 58° apparent viewing angle and 6.5 ft minimum focus distance make this Cosmos binocular well-suited for a wide range of viewing tasks.
In addition to displaying bright and contrast-rich views, this Cosmos binocular uses a nitrogen-filled housing to provide fogproof and waterproof performance; the housing is also wrapped in a slip-resistant rubber armoring that improves handling in wet and cold conditions. Twist-up eyecups with multiple click-stop positions and a 14mm eye relief enable a comfortable viewing distance for almost any viewer.
