Astronomik CLS CCD Nebula Filter - Clip Filter for Canon EOS cameras with Full Frame Sensor

Astronomik CLS-CCD Nebula Filter for Astrophotography

This filter is suitable for photographing nebulae, star clusters and also galaxies even from close to the city. The contrast of the deep-sky objects is enhanced, because the light of the artificial illumination is blocked as far as possible. This allows you to expose 3x longer before the sky background is brightened. The CLS CCD filter thus improves results whether you are working near cities or under dark skies far from settlements.

The CLS CCD filter is ideally suited for photographic use on telescopes of all apertures with focal ratios from f/15 to f/2.

How the CLS-CCD filter works:

The filter completely blocks the emission lines of low and high pressure lamps (mercury (Hg) and sodium (Na)) and the lines of airglow. This improves contrast everywhere, even under dark alpine skies.

All important emission lines of astronomical objects are transmitted. The filter also blocks infrared light (IR light). An additional IR blocking filter is therefore not necessary.

The Astronomik Broadband Clip-Filter for Canon EOS full-frame sensor cameras

The clip filter is optimized for use with normal camera lenses and for telescope use.

The filters sit securely and tension-free in the camera. Assembly and disassembly are easy with your finger, without tools! No changes to the camera are required to use the filters!

Note: the optical viewfinder does not work with installed EOS XL Clip-Filter, as the flip-mirror is fixed in the upper position!

The challenge:

Do you own a Canon EOS digital camera 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 Clip-Filter system you can take care of all of these problems at once!

The patented Astronomik Clip-Filters are made of black anodized aluminum and laser-cut on state-of-the-art machines. They 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 operational!

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.)

Compatibility:

Canon EOS 5D and 6D with full-size sensor are compatible.

5D Mk I will work without LiveView only, the 6D MkII will not work with XL Clip-filters.

Please note that the XL-Clip filters will not work with the Canon 5DS, 5DSR, and the 5D Mk IV.

The filters are also not suitable for Canon EOS, EOS M, EOS RP and EOS RP Astro!
