The 10x50 Granite Binocular from Celestron is a feature full binocular with optical offerings usually found only in very high-end scopes. Extra-low dispersion (ED) glass creates edge-to-edge sharpness with near exact colour fidelity and virtually no curvature or image distortion. Full broadband multi-coatings allow for the maximum light transmission and vivid colour saturation. The BAK-4 prisms have dielectric high reflectivity coatings contributing to the brightest possible images, while phase coatings correct out-of-phase light for the highest possible contrast.
The stylishly modern, open frame hinge design is comfortable to hold and adds to the light weight. Nitrogen purged, this Granite scope is fogproof and waterproof. A rubber covered magnesium body protects the optical investment. The focus knob, dioptre ring and twist-up eyecups are all made of metal, ensuring rugged longevity. To add some glaze to this already frosted cake; they are lead and arsenic free making them eco friendly.
