Product Description

The Celestron SkyMaster 15-35x70 Zoom Binoculars are large-aperture, high-power binoculars engineered for long-range terrestrial and astronomical viewing. Featuring a versatile zoom range from 15x to 35x and massive 70 mm objective lenses, these optics gather plenty of light for bright, detailed views of distant landscapes, wildlife, celestial objects, and horizon-level events. Fully multi-coated optics and BAK-4 Porro prisms deliver improved contrast and resolution, while long eye relief makes viewing comfortable for extended sessions. A central focus wheel, diopter adjuster, and included tripod adapter help you dial in sharp focus and steady views.
