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.
Astronomik CLS CCD Light Pollution Filter - T-Thread Mount
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.

- great LPS filter
I live in a red-white zone and this filter really helps cut out the LP. The filter holder is sturdy with nice threads that go on and off easily. If you don't live in a dark location this filter will really help bring out the objects in your astrophotos.

- Questions & Answers
Product QuestionsIs this also good for unmodified - original - DSLR? I have Sony a6000 and someone said that a person having original DSLR should use CLS version rather than CCD version.Question by: Jinyoung Heo on Oct 11, 2015 5:42:00 PMThe CCD version of the CLS filter will cut off the UV and IR wavelengths. This only necessary if your telescope system uses any refractive elements. Since your unmodified a6000 is unmodified, it will have UV/IR cutoff filtter on top the sensor. Getting the CCD version of the sensor will do nothing for you unless to you plan to modify your camera in the future.Answer by: Jonathan Cheek (Admin) on Oct 12, 2015 2:37:00 PM
