2" UHC / LPR Filter

About this product

The Celestron 2" UHC / LPR Filter is a high-performance optical filter designed for astronomy enthusiasts. It enhances contrast and color in celestial images by selectively reducing light pollution from artificial sources like mercury and sodium vapor lamps, as well as natural sky glow caused by atmospheric oxygen emission. The filter uses advanced multi-layer dielectric coatings with plasma-assisted and ionbeam-hardened technology for durability and resistance to scratching. With over 97% transmission across its passband and sharp cutoffs, it delivers bright, sharp images with minimal distortion or color shift. Its robust construction protects the optical glass, ensuring reliable performance during extended stargazing sessions. Compatible with a wide range of telescopes and cameras, this filter improves visibility of emission nebulae under both light-polluted and dark sky conditions.
