Astronomik UHC Clip-Filter EOS M APS-C
- 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 UHC Clip-Filter EOS M APS-C
You will enjoy using your Astronomik UHC filter because you will see more stars and more details in deep-sky-objects compared to using filters from all other manufacturers.
The Astronomik UHC (Ultra High Contrast) filter allows the transmission of nearly 100% of the radiation from both O-III and the H beta lines. Though the second window for the H-alpha-line is not intended for visual observing, it is important, if the filter is used with an electronic device. All annoying, scattered light from other wavelength sources, including local artificial light pollution, is reliably filtered out. With this strong blocking of the sky background an unexpected wealth of detail becomes visible for gas nebulae and planetary nebulae.
Astronomik UHC filters’ astounding high light transmission brings better views of deep-sky-objects even to small telescopes! The high transmission of our optical glass filters means that enough light is available to allow successful visual observations with telescopes beginning at 2" (50mm) aperture. Our Astronomik filters are optimized for use with telescope focal length f / ratios of f/4 to f/15. Transmission losses and chromatic distortions, which arise with other filters, only occur with Astronomik filters when extremely bright aperture ratios of 1:2 and more come into play. Another major advantage of our Astronomik UHC filter is the high optical quality of the filter glass. When using Astronomik UHC filters you will quickly notice the same needle-sharp stars which you are familiar with from your astronomical instrument without any filter!
Important: Full Spectrum modified cameras will need an additional IR-block-filter.
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:
- typ. 95% transmission at 486nm (H-beta)
- typ. 95% transmission at 496nm (OIII)
- typ. 95% transmission at 501nm (OIII)
- typ. 95% transmission at 656nm (H alpha)
- optimum position of transmission for telescopes with focal ratios from f/10 to f/3,5
- Entire Blocking of annoying wavelengths
- Ideal All-round Deep Sky filter even for small telescopes
- Not sensitive to humidity or aging
- Excellent carrier material. The optical performance of your telescope is not reduced by the filter in any way.
- 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
- 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
