BK7 Porro Prisms

50mm Objective Lens
Multicoated Optics
The 7x50 Cometron Binoculars from Celestron feature 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. These entry-level astronomical binoculars will provide you with clear views of the moon and meteor showers or can provide you with hours of casual star-gazing.
Rubber eyecups optimize the long eye relief and block stray light from leaking in from your peripheral vision and can be folded down for eyeglass users. A center focus wheel gives easy access with either hand for precision focusing. These full-size binoculars are 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.
