Pinnacle of Optical Design
Celestron Granite ED Series Roof Prism Binoculars are the pinnacle of optical and mechanical design. They stand up well against the much more expensive European and higher end Japanese manufactured binoculars at a fraction of their cost - a real value!
Granite ED Binoculars feature ED (Extra-Low Dispersion) glass, delivering edge-to-edge sharpness with excellent color correction and razor sharp images while virtually eliminating chromatic aberration.
State-of-the-art modern open frame style provides an excellent grip and is comfortable to handle (even single handed) with the reduced weight.
The body is made of magnesium alloy which is lighter than aluminum and more rugged and tough for handling in any environment.
