Nebula & Light Pollution Filters

Our L2P filters are designed to be used the same way that you would use a regular Astrodon Luminance filter, either by itself or as part of a LRGB filter set. The L2P filter differs from our standard Astrodon Luminance filter in that, in addition to the...

For Solar Observation use only in combination with Baader AstroSolar Safety Film!Eliminates the color error of economy refractors.Clearly puts the real quality of the lens on display.Removes the bluish "hue" (=lack of contrast) during lunar-, planetary-,...

Selective contrast filter, for all reflector and refractor telescopesFilters out specific wavelengths, especially those caused by streetlight and most importantly their scattered light which lightens up the night skySelective blocking retains natural...

The Baader Planetarium UHC-S Nebula filter excels at delivering a high-contrast and natural view of emission nebula - without excessive dimming and loss of background star fields. The perfect filter for viewing emission nebula from light polluted skies,...

Delivers the absolute highest contrast views of many diffuse and planetary nebula. For many objects, the Baader O-III reveals a level of intricate detail that rivals the best deep sky photographs. Our favorite filter for the majority of nebula,...

Features Take beautiful images of deep-sky objects from light-polluted suburban locations with the Rowe-Ackermann Schmidt Astrograph 11 (RASA 11) using this light pollution suppression filter Custom designed to replace the RASA’s optical window, so you...

FeaturesEnhance your 8" Rowe-Ackermann Schmidt Astrograph (RASA) by blocking light pollution, improving image contrast, and darkening the sky background. This filter selectively blocks wavelengths of light from sources of light pollution, such as...

Features The 1-1/4" OIII narrowband filter isolates just the two doubly-ionized oxygen lines (496 and 501nm lines) emitted by planetary and emission nebulae, while blocking the rest of the overall spectrum of light Celestron Oxygen III Narrowband Filter...

Features The 2" OIII narrowband filter isolates the two doubly-ionized oxygen lines (496 and 501 nm lines) Filter has ultra-hard, vacuum-deposited coating Eliminates un-natural colored halos surrounding bright stars Celestron Oxygen III Narrowband Filter...

Features Our 1-1/4" Light Pollution Reduction (LPR) Filters are designed to selectively reduce the transmission of certain wavelengths of light, specifically those produced by artificial light Celestron UHC/LPR Filter - 1.25 inOur 1-1/4" Light Pollution...

Features Our 2" Light Pollution Reduction (LPR) Filters are designed to selectively reduce the transmission of certain wavelengths of light, specifically those produced by artificial light Celestron UHC/LPR Filter - 2 inOur 2" Light Pollution Reduction...

Blocks common spectral lines from lighting sources. This filter provides balanced color for the visible spectrum while blocking most emission from metal-halide and vapor lamp sources which together contribute to sky glow.     Filters designed...
