The Celestron Granite 9x 33mm Binocular is the pinnacle of optical and mechanical design. Granite offers all the features you'd expect from a top-of-the-line binocular, including ED (Extra Low Dispersion) glass. The ED objective lenses and fully multi-coated optics provide excellent sharpness and color correction, while virtually eliminating chromatic aberration. Granite also features BaK-4 prisms with dielectric and phase coating to increase light transmission and overall image quality.
As the name implies, Granite binoculars are made to withstand the test of time. They are constructed from magnesium, which is tougher and lighter than aluminum. Granite also features metal-not plastic-twist-up eyecups.
Joining the beloved Granite series is the 9x 33mm model. This new model provides an excellent balance between performance and comfort, weighing just 20oz. The 9x 33mm provides a wider field of view compared to 42mm binoculars, making them an excellent choice for travel, sports and outdoor activities.
