Celestron Basic Moon Filter - 1.25in   The Moon has the distinction of being the most often viewed celestial object through backyard telescopes. It is undoubtedly beautiful and mysterious, and is one of those constants in our lives that connects us...

Celestron IR-Cut Filter for Color Skyris Cameras   Color CCD cameras such as the Skyris color planetary cameras are very sensitive across the visual spectrum, as well as in infrared. Some telescopes may correct for chromatic aberration, but are not...

Celestron Light Pollution Imaging Filter, RASA 11   Get the most out of your Celestron Rowe-Ackermann Schmidt Astrograph 11, even under light-polluted skies, with this Light Pollution Imaging Filter, custom-designed for the RASA. No matter which...

Celestron Light Pollution Imaging Filter, RASA 8   Light pollution in the night sky can significantly degrade contrast in astronomical images. This is especially true when using very fast telescopes like the 8” RASA because the sky background...

Celestron Neutral Density Filter, 1.25in   The Neutral Density Moon Filter attaches to a 1.25” eyepiece to lower the amount of light entering the eyepiece by 87%. The Moon is one of the most viewed objects in the sky, but you shouldn’t...

Celestron Oxygen III Narrowband Filter - 1.25in 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 - 2in   The 2" OIII narrowband filter isolates just the two doubly-ionized oxygen lines (496 and 501 nm lines) emitted by planetary and emission nebulae, while blocking the rest of the overall spectrum of light...

Celestron UHC/LPR Filter - 1.25in   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. This includes mercury vapor,...

Celestron UHC/LPR Filter - 2in   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. This includes mercury vapor, and...

Celestron Variable Polarizer, 1.25in   When you want to selectively reduce the brightness of celestial objects for a customized view, the Variable Polarizing Filter is the perfect choice. Unlike regular Moon Filters and Neutral Density Filters, the...
