Celestron Telescope Accessories LPR Filter - Model A - for 1-1/4 Inch Eyepieces

Celestron's light pollution reduction (LPR) filters make deep-sky observation and astrophotography possible in urban areas. That means you can capture stunning views of the Orion Nebula, the Rosette Nebula, the North American Nebula, the Veil Nebula and the Helix Nebula, plus many, many others from a nearby parking lot! LPR filters work by reducing transmission of light wavelengths produced by artificial light. This includes mercury-vapor, and both high- and low-pressure sodium-vapor lights. They also block "sky glow," or unwanted natural light, caused by neutral oxygen emission in our atmosphere. While blocking unwanted light, Celestron LPR Filters permit transmission of more desirable wave-lengths, including hydrogen alpha, hydrogen beta, doubly ionized oxygen and singly ionized nitrogen. This will improve viewing of emission nebulae, both from urban and rural settings. Celestron's new LPR Filters are made of high-quality, flat, polished optical glass with more than 40 layers of optical coatings. They're not laminated! They are, however protected with a broadband anti-reflection coating to prevent ghosting and to improve contrast. With it, they provide performance and contrast superior to that of competitive models. That makes them a must-have accessory for urban stargazers! --jtyl
