Pinnacle of Optical Design
Granite Binoculars feature ED glass and deliver 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 which is much lighter than aluminum and more rugged and tough for handling in any environment.

When Celestron announced they were introducing a new line of premium roof prism binoculars, it was assumed they would be the return of the Noble series with a few minor improvements, and then renamed. The Granites have proved to be nothing of the sort. They are substantially better optically and mechanically than the Nobles. At the OpticsShop, we have yet to see a better image quality in 42mm and 50mm roof prism binoculars manufactured in China. In our view, these represent the best yet from the Chinese optical factories, and side by side with some of the best European and Japanese binoculars for image quality, at a fraction of the price.
The 10X50 Granite in particular is extremely bright and sharp, with a weight around the neck that feels like a 42mm binocular. Under test at our North Yorkshire test reserve, the 10X50 was usable right up to near darkness. The 8X42 model was close behind.
The objective lenses include a low dispersion (ED) element for much improved correction for chromatic aberration, the entire optics have a broadband multi-coating applied to each optical surface, the prisms are phase corrected and the body is rubber armoured magnesium. All the Granites are open hinged and have the same slim-line feel in the hand, (someone has done their homework)! They have a wide lanyard, rainguard, and rubber objective caps that can be left hanging or removed completely. There is also a complimentary harness included for those who do not wish to carry them around the neck..........a nice touch. They are complete with a soft carry case.
The Granites need to be seen to be believed. We keep them at the OpticsShop in Northallerton for viewing. You are welcome to try them.
