Astronomik CLS Light Pollution EOS Clip Filter: £108.00

To Fit Canon EOS Cameras

The superb CLS filter now available to fit directly to your Canon EOS DSLR camera allowing use with Canon lenses and T adaptors without fuss and protecting your sensor from dust.

Do you have a Canon EOS digital camera (300D, 350D, 400D, 450D, 500D,1000D 20D, 20Da, 30D, 40D), and also use it for astro-imaging? Then you have surely encountered the following problems:

Large filters for large camera lens objectives are very expensive
If you place a filter holder between your camera body and lens you loose the ability to focus to infinity
For very fast (low f/ number) telescopes like the Vixen R200SS or the Takahashi “Epsilon” astrograph. a filter drawer or a filter wheel cannot be used since the distance to the corrector lenses would be changed
With long exposure times your camera’s sensor chip is exposed to more dust

With the Astronomik EOS Filter Clip System you can immediately take care of all of these problems!

The patented Astronomik EOS Filter Clip System is black anodized aluminum and laser-cut on state-of-the-art modern machines. It can be inserted within seconds directly into the EOS camera body. There are no changes necessary and all lens functions (focus, screen, image stabilization) remain functional!

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 EOS Filter Clip System. The EOS Filter Clip System also acts as an outstanding dust shield, which prevents the possibility of dust settling on the sensor during long time exposure.

The Astronomik CLS filter is the right filter to gain the contrast of nearly all objects under light-polluted skies with all sizes of telescopes. Due to the design of the transmission curve the filter reduces the sky background and gas nebulas, planetary nebulas as well as open clusters, globular clusters and galaxies are seen better. The Astronomik CLS blocks the emission of Hg and Na streetlights as well as all Skyglow-lines . All major emission lines from deep-sky objects are passed without surpression. From the research done on emmission lines the most important part of the eye´s night-sesitive region is passed with maximum transmission with our CLS filter.
