Astronomik CLS CCD Clip-Filter EOS M APS-C (For Full Spectrum Cameras)
- Large filters for large camera lens objectives are very expensive
- If you are using an Off-Axis Guider stars will be dimmed on your autoguiding camera when a 2" round mounted filter is threaded to a corrector being ahead of the reflecting prism from the light path.
- 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-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 M camera body. There are no changes necessary and all lens functions (focus, screen, image stabilization) remain functional!
The clip filters for Canon EOS M Mirrorless cameras can be used with all lenses known till today with the EF-M Bayonet. With the adapter EF-M to EF/EF-S all Canon lenses and all lenses from other manufacturers with Canon Bayonet can be used. Of course, you may use the filters when the camera is attached to your scope too.
The filters are optimized to be used with normal lenses and with a telescope.
Use Astronomik filters for your EOS M and enjoy marvelous images with an ultra light equipment!
Astronomik CLS CCD Clip-Filter EOS M APS-C (For Full Spectrum Modified Cameras)
The Astronomik CLS CCD is suitable under light-polluted skies for DSLR Cameras which have been modified for Full Spectrum sensitivity. 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/2 and above.
Main useThe 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.
- Easier resolution of Double Stars.
- With the EOS-Clip model, photography with DSLR cameras is feasible even unter extreme light-polluting conditions without shifting the white balance.
- The 1,25" and 2" 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
Hint for a very usefull accessory:
The EOS M, M10 and M3 are a little bit difficult to use for deep Astrophotography because any exposure time longer than 30sec can be done via pressing the exposure-button only, or via Infrared. (Up to 30sec can be set in the camera, but USB control for longer times does NOT work.) However all IR-Intervalometers we tried, do not work properly: When set to Bulb-Mode there are two IR-commands required, the first to open the shutter, the second one for closing it at the end of the exposure. All normal IR-Intervalometers do not handle that correct and a break of the length of the exposure time is the result. Good news: There is a device that handles it correct, the "SteveMRI MultiCam LEI Intervalometer" (http://stevemri.no-ip.co.uk/) changes the signal from a normal programmable intervallometer to proper IR-commands! At the beginning of the exposure a signal is sent to the camera, a second one when the exposure time has ended. With this device all features of a normal programmable timer (Time-to-start, length of exposure, break between exposures, number of exposures) can be fully used. If you have a advenced device for exposure-ramping even this will work: Simply plug the cable into the LEI Intervalometer and it will convert all signal to proper IR-Commands.

Watch the following video to see how easy the clip filters can be used:
- 95% transmission at 486nm (H-beta)
- 95% transmission at 496nm (OIII)
- 95% transmission at 501nm (OIII)
- 97% transmission at 656nm (H-alpha)
- Pass from 450 to 520nm and from 640 to 690nm
- Parfocal with other Astronomik filters
- Glass thickness: 1mm
- Completely resistant against high humidity, scratches and aging effects
- Diffraction limited, the filter will not reduce the optical performance of your telescope!
- Astronomik filters are delivered in a high-quality, long lasting, filter box
- Since 2008 we do ship filters with a completely new design. Any kind of halo or strange reflection is a matter of past
- The filters can be used with Canon EOS M1, M10, M3, M5, M6, M6 MkII, M50, M50 MkII, M100 and M200 bodies. (We never got a M2 in Europe.)
- The filters can be used with all EF-M lenses
- The Clip filter may be used with all other Canon lenses. (Using the Canon adapter from EF-M to EF)
- The Clip filter for Canon APS-C fit into the Original Canon Adapter from EF to EF-M bayonet
