The Optolong L-Pro 2" Mounted Filter is a versatile light pollution filter ideal for both astrophotography and visual astronomy. Engineered to reduce transmission of artificial light from sources like mercury vapor and sodium lamps, this filter dramatically enhances contrast and color balance when observing or imaging from urban environments.
Its selective passbands permit key emissions—such as H-alpha, H-beta, OIII, NII, and SII—while suppressing unwanted skyglow and artificial interference. Whether you’re capturing wide-field nebulae or zooming in on star clusters, the Optolong L-Pro ensures a vivid, balanced view that preserves natural star colors and fine nebular structure. Its high-quality glass and precision coatings make it a reliable tool for serious observers and imagers alike.
