Clip-Filters for Canon Full-Format Cameras 5D Mk II, 5D Mk III and 6D.
These Clip-Filters can be installed with your fingers only. Mounting and removing the Clip-Filter is quick and easy. It can be done at any time. No tools or modifications to the body are necessary to use the Clip-Filters.
Since 2007 we do offer our extremly popular Clip-filters. Customers looking for a filter to be used with the "big" Bodies containing the Full-Format sensors, had to buy large (and expensive) filters to be screwed in front of a lens, as Clip-Filters were available for the APS-C sized bodies only.
All customers asking for Clip-filters for the Full-Format bodies were told "We are working on it, please wait!"
Now waiting is over, and we are proud to show you the result of our R&D:
Clip-Filters for Canon Full-Format Cameras 5D Mk II, 5D Mk III and 6D. (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
These Clip-Filters can be installed with your fingers only. Mounting and removing the Clip-Filter is quick and easy. It can be done at any time. No tools or modifications to the body are necessary to use the Clip-Filters.*

If you are new to astrophotography and looking for your first filter: We do recommend getting the Astronomik CLS!
The CLS gives you maximum contrast due to it effective surpression of artifical light pollution, but still gives you neutral and well balanced colors. With the Astronomik CLS you can do very deep images of amazing quality even form a urben/suburban observing site!
For the advanced Astrophotographer we do offer a wide selection of filters: Perfect accessories for all kinds of astrophotography. To compile a usefull selection of filters for your obeserving goals we would be happy to give you advise, either via phone or eMail.
The full range of Astronomik filters is available as Full-Format Clip-Filters now. NEW: The OWB filter for daylight-photography with modified cameras is available now too.
* You might want to modify your camera to get a maximum sensetivity at H-alpha and SII for Astrophotography. But this has nothing to do with the Clip-Filters! You may use the Clip-Filters without any modifications to the body. (But some filters like H-alpha and SII-CCD might not make sense with an unmodified camera.)
Mounting the Astronomik EOS XL Clip-Filter:
Mounting the Astronomik EOS XL-Clip Filter is very easy: You don´t need any tools and filters may be changed at night without any problems.
Activate "Mirror Lockup" in the Custom-Functions Menue and press the exposure button once: The flip-mirror goes up and stays there.
Now slide the XL-Clip-Filter into the body and press it in, until it rests on both arms (right & left).
Deactivate the Mirror-Lockup and your camera is ready for imaging!
The installed XL-Clip-Filter fixes the flip-mirror in the upper position. -You can´t use the optical viewfinder as long as the XL-Clip Filter is installed. For Searching, focusing and centering you should use the LiveView monitor on the back of the camera or the remote-controll via USB cable. All functions like Autofocus and Image-Stabilization remain fully functional.
The fixed flip-mirror does not cause any kind of problems or error-messages!
Removing the Astronomik EOS XL Clip-Filter:
Removing the Astronomik EOS XL Clip-Filter is very simple: Pull the filter out with one finger an on arm (either right or left), get the filter with two fingers and put it into it´s storage box.
The flip-mirror goes down and the camera is working as before.
This SII Filter is suitable for imaging of SII-regions from observation sites with light pollution and from dark sites as well. The contrast between an object glowing at 672nm and the background is increased enormous!
Due to the combination of the narrow bandwidth of 12nm and the high transmission of typically 96% the filter gives you an contrast boost, as all unwanted light from other wavelengths than 672nm is blocked form UV up to the IR. This results in an very dark background compared with any filters with a higher bandwidth
The FWHm of 12nm is optimized for typical DSLR cameras with CMOS sensors and CCD cameras with a normal/high dark current: With these cameras the background signal in images taken from heavily light polluted sites is dominated by the dark current of the sensor, not by fluy coming from light pollution. In this case a further reduction of FWHM does not improve the image, as the background will not get darker. Compared to the 6nm filters you have more stars in the field of view which gives you more guiding stars when working with an integrated/dual guiding chip!
Due to the new MFR coating technique you may use one single filter on all instruments up to f/3 without a significant reduction in performance.
The Astronomik H-alpha filter MUST NOT BE USED for solar observation!
Technical data of the filter:
- Guaranteed Transmission of more than 90% at both SII lines (671,7nm und 673,0nm)
- Typical Transmission of 96% at both SII lines (671,7nm und 673,0nm)
- Full-Width-Half Maximum (FWHM): 12nm
- perfect blocking of unwanted light from UV up to the IR
- parfokal with all Astronomik filters
- MFR Coating technique: Usable with all optics up to f/3
- Thickness of 1mm
- Not sensitive to moisture, scratch resistant, not aging
- opticaly polished substrate, striae-free and free of residual stresses
- High quality storage box
Imaging with Narrowband-Emissionline Filters
If you have to observe from light polluted sites (like most of us...), imaging with Narrowband-Emissionline filters is the best way to take great images, as all kind of light pollution can be blocked very effective! Normaly an H-alpha filter should be your first step into this amazing field of astrophotography! With an Narrowband H-alpha filter you will be able to take deep and contrasty images even wih very heavy light pollution or with the full moon high up in the sky!
If you look at other astrophotos, an H-alpha is the best choice for all nebulas glowing red! An OIII filters expands your imaging possibilities, as you are able to image all greenish/blueish structures. Planetary nebulas and star forming regions are great targets! The SII filters completes your HSO-set of filters. With these three filters you are able to process your images like the ones from the Hubble space telescope!
The h-beta filter is not available in a 6nm version, as this filter has nearly no meaningfull application. To illustrate this, there are two images shown below: Both were taken with a unmodified Canon 650D. Even as the camera has a sensitivity of less than 10% at H-alpha, there is some signal und structure in the h-alpha image, while you cannot see anything on the image taken with an H-beta filter!
Operation of the filter:
The filter blocks all unwanted light from artifical light-pollution, natural airglow and moonlight. Especially light from High- and Low-Pressure Sodium and mercury lights and all lines of natural airglow are 100% blocked. The filter increases the contrast between the sky-background and objects glowing at the SII line at 672nm.
Tips and Hints for more applications:
Using the SII filter together with OIII-CCD and H-alpha-CCD filters you make produce false-color emission line images (HSO) in the same way as the Hubble-Space telescope. This is possible even from heavyly light polluted sites
If want to image faint objects in starcrowded regions of the milkyway, propably using short focal lengths, the 6nm filter will be the better choice, as the number of stars is reduced by a factor of ~2. You should even take the 6n mversion if you have a camera with a low thermal current or if you have to observe from a really heavily light polluted site.
