The 7x50 Cometron Binocular from Celestron features large objective lenses and multicoated optics to provide bright and crisp images. The BK7 porro prism design provides a rich depth of view and contrast. This entry-level astronomical binocular will provide you with clear views of the moon, meteor showers or just casual star-gazing.
Rubber eyecups optimise the long eye relief and block stray light from leaking in from your periphery vision, and can be folded down for eyeglass users. A centre focus wheel gives easy access with either hand for precision focusing. This full-size binocular is also appropriate for casual use for sports, hunting or nature viewing in full daylight and low-light. The comfortable field of view and large objective lenses create an optical system well-suited for both terrestrial and extraterrestrial viewing.
