Product Info for Celestron OptiView 10x50 LPR Binocular 72102
Celestron OptiView 10x50 LPR Binoculars 72102 have built-in light pollution reduction (LPR) filters designed to selectively reduce the transmission of certain wavelengths of light, specifically those produced by artificial light (see chart).
This includes mercury, and both high and low pressure sodium vapor lights common in most city street lights. In addition, they block unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. sky glow). As a result, 10 x 50 OptiView LPR Binoculars #72102 darken the background sky, making deep-sky observation of nebulae, star clusters and even galaxies possible from urban areas.
While blocking unwanted light, Celestron OptiView LPR 10x 50 Binoculars permit the transmission of more desirable wavelengths including hydrogen alpha, hydrogen beta, doubly ionized oxygen and ionized nitrogen. This will improve your views of emission nebulae, both from urban and rural settings.
Celestron OptiView LPR Filters are made of high quality, flat, polished optical glass with over 40 layers of coating. They?re also protected with a broadband anti-reflection coating to prevent ghosting and to improve contrast. Celestron OptiView-LPR 10X50mm Binoculars carry Limited Lifetime Warranty.
