Astronomik CLS-CCD for Cameras with IR Filter Removed - Canon EOS APS Clip

A CLS CCD Light Pollution Filter - Canon EOS Clip (For Cameras with IR Filter Removed) by Astronomik:

The Astronomik CLS CCD is suitable under light-polluted skies for DSLR Cameras, which have been remodeled for astronomical use. The filter enhances the contrast between all deep-sky objects and the background.

The CLS-CCD Filter enhances the contrast between astronomical objects and the background. Due to the wider transmission curve compared to UHC filters, a greater amount of light will pass the filter. Stars will be less dimmed. This filter has been optimized to block as much spurious light as possible and simultaneously provide the best performance for 'useful' light. A good filter for DSLR-, CCD- and film b/w-photography as well as observation of deep-sky-objects with telescopes or photo lenses of all aperture f/3 and above. 

The filter blocks completely emission lines of artificial light sources like streetlights (e.g. sodium- and mercury-vapor) as well as the airglow. All 'important' emission lines as well as the spectral range of the night-adapted eye are being passed. The supplementary IR-blocking layer allows the use for DSLR- and Webcams without an integrated IR-block filter.

Other uses for the Astronomik CLS CCD Light Pollution Filter include easier resolution of Double Stars and with the EOS-Clip model, photography with DSLR cameras is feasible even under extreme light-polluting conditions without shifting the white balance. The 1.25-inch and 2-inch socket models can be used for observations from light-polluted areas. If you plan to create color images from emission line data, our CLS-CCD filter is a great choice for the Luminance channel.

About the Astronomik Clip-Filter System: 

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.)

Note: For Photographers interested in daylight IR-Photography a "MC-modification" is possible for some cameras. If you are interested in this, please send us a short mail. We will give you more details. The "MC-modification" gives you no advantage for normal astrophotography! If you have a full-frame EOS camera, like the 5D or 6D, you should buy the Astronomik CLS-CCD XL EOS Clip Filter instead.

Beautiful pictures

I bought a new Canon 1100D (T3) modded camera last month. After much research, I decided to try the CLS-CCD filter. I tested it by taking pictures of M33 both with and without the filter and then processing data exactly the same way. The color, contrast, and detail with the filter was significantly better. I will use it on ALL my pictures in the future.
