Light Pollution Filters

The Astronomik CLS is a budget filter for visual observation, Black & White photography and CCD photographs of nebulae, galaxies and star clusters with astronomical instruments of any size.

The L-Pro (L-Professional) filter is designed to improve the visibility of various deepsky objects. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lightings

The P2 is the most popular filter for suppressing light pollution with modern CCD, CMOS and DSLR cameras. Japanese made for the highest possible quality.

The L-Pro (L-Professional) filter is designed to improve the visibility of various deepsky objects. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lightings

Optolong L-Pro (L-Professional) filter is designed to improve the visibility of various deepsky objects. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lightings including mercury vapor lamps

The Astronomik CLS is a budget filter for visual observation, Black & White photography and CCD photographs of nebulae, galaxies and star clusters with astronomical instruments of any size.

IDAS Night Glow Filters enhance the contrast of astronomical emission nebulae against a sky with both man-made and natural* sky glow sources, yet preserve color balance of broadband objects such as galaxies.

The L-Pro (L-Professional) filter is designed to improve the visibility of various deepsky objects. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lightings

The Optolong L-Pro (L-Professional) filter is designed to provide maximum luminosity of the spectrum other than those areas caused by light pollution

The Antlia Triband RGB Ultra filter is designed for light pollution suppression for OSC and Mono cameras. The spectral design selected the most substantial information in the RGB bands.

The Astronomik CLS CCD is suitable under light-polluted skies for DSLR Cameras, which have been remodeled for astronomical use. The filter enhances the contrast between all deep-sky objects and the background.

For the vast majority of us, we live in cities or locations with a lot of street lights. Light pollution in the night sky can significantly degrade contrast in astronomical images.

Get the most out of your Celestron Rowe-Ackermann Schmidt Astrograph, even under light-polluted skies, with this Light Pollution Imaging Filter, custom-designed for RASA by Celestron and Astrodon.
