Pinnacle of Optical Design
Celestron Granite Series Roof Prism Binoculars are 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 phase and dielectric coatings 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 alloy, which is tougher and lighter than aluminum. Granite also features metal—not plastic—twist-up eyecups.
Joining the beloved Granite series is the 7x33 model. This new model provides an excellent balance between performance and comfort, weighing just 21 ounces. The 7x33 provides a wider field of view compared to 42mm binoculars, making them an excellent choice for travel, sports and outdoor activities.
