Astronomik CLS EOS / EOS XL Clip Filter


Astronomik CLS EOS or  EOS XL Clip Filters (NOT IR Blocked)

The patented Astronomik Clip-Filter 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 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.)

This broadband light pollution filter works on all objects for both visual use, and imaging with standard and Baader modded DSLR cameras. Blocks Sodium, Mercury and air-glow emission.

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.

Main use

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.

Can also be used as an effective minus violet filter by refractor owners.

Decent filter for my unmodded EOS600D camera. Works well and helps pull out more detail. push the exposure with higher iso settings and you get a green/blue cast. Otherwise fine. Dave advised me what setting I needed to try and now getting 6-8 minutes images with nice contrast sky. Can only be used with EF lens and used with 70-300mm Zoom for great shot of Andromeda.
