For astro-imaging, sensitivity in the red (the H-alpha line) is desired and is achieved by the removal of the camera’s internal IR blocking filter. Hence, Canon sells it’s cameras with an internal “IR-blocking filter” over the sensor to remove the over abundance of ‘red’ due to Infrared from ordinary photos. Regular photographic digital camera sensors have a very small sensitivity in the H-alpha line portion of the spectrum which is bad for regular photographs but very important for astro-imaging. The Astronomik Clip-Filter System does not have anything directly to do with a digital camera’s “IR-band blocking filter”. Questions and answers about the Astronomik Clip-Filter System: Important: Not suitable are cameras offered before 2003 and all varieties of the Canon EOS 1D and EOS M. The "MC-modification" gives you no advantage for normal astrophotography! If you are interested in this, please send us a short mail. Yes: This version fit´s into the Canon Adapter EF to EF-Mįor Photographers interested in daylight IR-Photography a "MC-modification" is possible for some cameras. List of compatible Canon EOS cameras: Canon EOSĤ00D / Digital Rebel XTi / Kiss Digital X Questions and answers about 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.)

There are no changes necessary and all lens functions (focus, screen, image stabilization) remain functional!Īlmost all Canon system lenses (with the exception of the genuine EF-S series lenses), all lenses (known to us) from third party manufacturers and all M42 and T2 lens adapters, can be used with the Astronomik Clip-Filter System. It can be inserted within seconds directly into the EOS camera body. The patented Astronomik Clip-Filter System is black anodized aluminum and laser-cut on state-of-the-art modern machines. With the Astronomik Clip-Filter System you can take care of all of these problems at once! With long exposure times your camera’s sensor chip is exposed to more dust.For very fast (low f/ number) telescopes like the Vixen R200SS or the Takahashi “Epsilon” astrograph, a filter drawer or a filter wheel cannot be used since the distance to the corrector lenses would be changed.If you place a filter holder between your camera body and lens you loose the ability to focus to infinity.Large filters for large camera lens objectives are very expensive.Do you own a Canon EOS digital camera ( List of compatibel cameras) for astro-imaging? Then you have surely encountered the following problems:
