Celestron Optiview 10 x 50 LPR Binoculars
Reduce reflections and glare, deepen the blue sky, intensify colors and penetrate haze with Celestron's OptiView filtered binocular. OptiView binoculars have integrated drop-down polarizing filters designed to block out unwanted glare and reflected light. OptiView binoculars are particularly useful for viewing outdoors over water and snow, or indoors for looking through glass or highly reflective areas- all without affecting the color of the object being observed. Scattered light from the Sun becomes polarized when reflected off of glass, water or even moisture particles in our atmosphere. Using a polarizer filters out all this unwanted light and reduces the affect of reflected polarized light (glare) in the earth’s atmosphere.
Celestron OptiView LPR binoculars 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 to the right). 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, OptiView LPR binoculars darken the background sky, making deep-sky observation of nebulae, star clusters and even galaxies possible from urban areas. While blocking unwanted light, OptiView LPR 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. Some examples of objects that will show improved contrast are: the Orion Nebula, the Andromeda Galaxy and the Lagoon Nebula. 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.
