  • The Astronomik CLS CCD Light Pollution Filter is presented in a 2" Mounted format.
  • Blocks the light of the spectral lines of mercury and sodium-vapor lamps and lets the largest part of the visible light and H-alpha emissions pass.
  • The Astronomik CLS CCD Light Pollution Filter is a good filter for DSLR-, CCD- and film b/w-photography as well as observation of deep-sky-objects with telescopes or photo lenses of all aperture f/3 and above.
  • This filter has been optimized to block as much spurious light as possible and simultaneously provide the best performance for 'useful' light.
  • The Astronomik CLS CCD Light Pollution Filter is suitable for use with telescopes of all aperture sizes.

Astronomik CLS CCD Light Pollution Filter - 2" Mounted



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.

The CLS-CCD Filter enhances the contrast between astronomical objects and the background. Due to the wider transmission curve compared to UHC filters, a greater amount of light will pass the filter. Stars will be less dimmed. This filter has been optimized to block as much spurious light as possible and simultaneously provide the best performance for 'useful' light. A good filter for DSLR-, CCD- and film b/w-photography as well as observation of deep-sky-objects with telescopes or photo lenses of all aperture f/3 and above

The filter blocks completely emission lines of artificial light sources like streetlights (e.g. sodium- and mercury-vapor) as well as the airglow. All 'important' emission lines as well as the spectral range of the night-adapted eye are beeing passed. The supplementary IR-blocking layer allows the use for DSLR- and Webcams without an integrated IR-block filter.

Other uses for the Astronomik CLS CCD Light Pollution Filter include easier resolution of Double Stars and with the EOS-Clip model, photography with DSLR cameras is feasible even under extreme light-polluting conditions without shifting the white balance. The 1.25" and 2" socket models can be used for observations from light-polluted areas. If you plan to create color images from emission line data, our CLS-CCD filter is a great choice for the Luminance channel.

I've tried many different LP filters and this one is hands down the best filter to date.
I can't say enough good things about this filter in a short review so bottom line.....The best out there.
I use the 60da and wasn't sure it would work to well not really knowing the specs on the factory mod but to my surprise it pulled in the photons and didnt clip the valuable data.
you would never know that the subs came from an area so polluted with light that you could almost read a newspaper in the dead of night from the skyglow and niegbors security lights.
don't waste your money on an economy filter.

The best Light Pollution filter Ive ever used.
Great contrast on galaxies from my backyard in the city.
