    A CLS Light Pollution Filter in a Full Frame XL Clip for Canon EOS cameras by Astronomik:

    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 Astronomik CLS 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. All the important emission lines, as well as the spectral region that the very well dark adapted eye can see, can pass through the filter.

    The filters are optimized for use with aperture ratios from 1:3 to 1:15. Transmission losses and chromatic distortions, which are problems with other filters, only appear with Astronomik filters when extremely bright aperture ratios of 1:2 and more are used. The CLS filter is suitable for use with telescopes of all aperture sizes and even works well with binoculars.

    The Astronomik CLS Light Pollution Filter is good for use under both dark and urban skies for reducing light pollution made by mercury-vapor lamps. For film photography and modified DSLR use, the CLS filter gives good performance and near perfect color balance. While this filter does perform well with webcam and video equipment under light polluted skies, it is not suitable for planetary use.

     

    Suitability:

    • Visual observation (dark skies): Good, to reduce light pollution by mercury-vapor lamps (streetlight)
    • Visual observation (urban skies): Good, an UHC-E or UHC filter is more suitable
    • Film photography: Very good, color balance is near perfect CCD photography: Good, when used with an additional IR-block-filter
    • DSLR photography (original): Good, colour balance shifted but contrast enhanced
    • DSLR photography (astro modified): Very good, color balance is near perfect
    • DSLR photography (MC modified): Good, when used with an additional IR-block-filter
    • Webcam / Video (Planets): Unsuitable
    • Webcam / Video (Deep Sky): Very good, if light pollution is a big problem

     

    About the Astronomik XL Clip-Filter System: The patented Astronomik Clip-Filter System for Canon full-frame cameras is black anodized aluminum and laser-cut on state-of-the-art modern machines. It can be inserted within seconds directly into any full-frame (5D and 6D, for example) EOS camera body. There are no changes necessary and all lens functions (focus, screen, image stabilization) remain functional! If you have a EOS Rebel, or other Canon APS-C sized camera body, you should purchase the standard-sized Astronomik CLS EOS Clip filter instead.

    [Exception: Does Not work with the Canon 5D Mark IV].

    Almost all Canon system lenses (with the exception of the EF-S series) and all M42 and T2 lens adapters, can be used with the Astronomik Clip-Filter System. The Clip-Filter System also acts as an outstanding dust shield, which prevents the possibility of dust settling on the sensor during long time exposure (The MC-Clear filter does not have a filter effect and only acts as a dust shield.)
