Celestron's Granite Binocular reaches a top-notch level of performance with state-of-the-art design that cost a lot less than you normally expect to pay. The ED glass, fully multi-coated lenses, and BaK-4 prisms with dielectric coatings combine to provide you with razor sharp details, excellent color correction, and maximum light transmission for the brightest images. An open-frame design offers comfort and ease of use, especially valuable over long periods of observation or when using with only one hand. The strong, lightweight magnesium body and waterproof and fogproof protection makes the Celestron Granite a great choice for the serious outdoor person.
