Astronomik CLS CCD Light Pollution Filter - SC Rear Cell


The Astronomik CLS CCD filter works best with DSLR cameras that have been repurposed for astronomical use in a light polluted environment. This filter brings out the contrast between deep-sky objects and the background.

As a result of the wider transmission curve this CLS CCD has when compared with UHC filters, more light will pass the filter. Stars will appear to be less dimmed. This filter has been configured to block as much artificial light as possible while supplying excellent performance for desired light. Makes a great filter for DSLR, CCD, and black & white film photography along with deep-sky observations using telescopes or photo lenses with f/3 and above apertures.

The Astronomik CLS CCD filter completely blocks emission lines of spurious light from sources such as streetlights. Meanwhile all critical emission lines as well as the human eye's night-adapted spectral range are bypassed. An auxiliary IR-blocking layer permits the use of DSLR and Webcams without an incorporated IR-block filter.

Alternative uses for this Astronomik CLS CCD Light Pollution Filter include easier resolution of Double Stars with the EOS-Clip version. Photography with DSLR cameras is possible with severe light polluting conditions without white balance shift. The 1.25" and 2" socket models can also be employed when observing from light polluted areas. For those who want to take color images from emission line data, the CLS-CCD filter is an excellent option for the Luminance channel.
