Granite ED Series

At the apex of optical and mechanical design is Granite ED, Celestron’s award-winning series offering all the features you’d expect from a top-of-the-line binocular. Extra-Low Dispersion (ED) glass objective lenses provide edge-to-edge sharpness and color correction while virtually eliminating chromatic aberration. Fully multi-coated optics and phase and dielectric coated BaK-4 prisms produce noticeably brighter images with enhanced resolution and contrast. It’s all protected by a durable, waterproof and nitrogen purged magnesium alloy exterior in an ergonomic open-frame body style.
