1.25" UHC / LPR Filter

About this product

The Celestron 1.25" UHC / LPR Filter is a specialized astronomy accessory designed to enhance night sky observation by reducing light pollution. Engineered with multi-layer dielectric coatings, it selectively blocks wavelengths from artificial sources like mercury and sodium vapor lights, as well as atmospheric oxygen emissions. This results in a darker sky background, increasing contrast for emission nebulae and other celestial objects. With over 97% light transmission across its 60nm passband, the filter maintains image brightness while improving detail visibility. Its 1.25" threaded size ensures compatibility with most standard telescope eyepieces and accessories. Built for durability with plasma-assisted, ionbeam-hardened coatings and a wipe-clean surface, it offers long-term reliability and performance. Ideal for both urban and rural stargazers, this filter improves astrophotography quality and observational clarity.
