The Baader UHC-L filter is a versatile anti-light pollution filter designed to block emissions from LED lamps in the blue part of the spectrum. It features two pass bands that transmit light emitted by all known emission nebulae, including the H-alpha and H-beta lines of fluorescent hydrogen and the OIII oxygen line.

The Baader UHC-L filter is an all-purpose anti-light pollution filter designed to block emissions from LED lamps in the blue part of the spectrum. It features two pass bands that allow light transmission from all known emission nebulae, including the H-alpha and H-beta lines of fluorescent hydrogen and the OIII oxygen line. This filter effectively reduces stray light from LED and traditional street lamps, blocks bluish car headlights, and minimizes the natural night sky glow (airglow/skyglow).

The OIII filters allow only light with a wavelength of 501 nanometers to pass through, corresponding to the spectrum lines of double-ionized oxygen. These lines are emitted by planetary nebulae and some emission nebulae, ensuring these objects remain visible while blocking out other light sources. This filtering effect enhances contrast and makes faint nebulae visible for the first time.
