SkyMaster 15-35×70 Zoom Porro Prism


SKU: SKU-1424 Tag:


Equipped with a large aperture and a broad zoom range, the Celestron 15-35×70 SkyMaster Zoom Binocular is an ideal choice for long-duration astronomical or long-distance terrestrial (land) use. The large objective ensures volumes of light are gathered to see better than smaller aperture models; and the easy zoom lever allows you set the optic on low-power to easily find your subject, then zoom in to detailed make up-close observations. This model was engineered with an exceptionally long eye relief to make it comfortable to look through for extended periods of time, while limiting eye strain. Because of the size and weight of the SkyMaster, Celestron includes a tripod adapter to provide a hands-free option and relieve arm-strain, reduce fatigue, and limit vibrations.
