I want to install a Ha filter (have not bought yet) as close as possible to the camera body of my Pentax K-1, similar to what the Baader Canon T-ring can do with the filter chamber built into the T-ring. Can this T-ring for the Pentax be able to have a filter installed like in the Canon T-ring with a filter chamber? If not, how can I get a filter as close as possible to the t-ring or camera body?

I want a connecting ring between my Pentax K200D and the Multi Purpose Coma Corrector # 2458400. The coma corrector fits to a Newtonian telescoop from GSO (Guang Sheng Optical, Taiwan), the F4 model (reflector 200mm, focus 800mm). The only thing is that the register distance between the corrector and the filmplane must be correct for Pentax K. Registerdistance is the distance from last lenselement from a Pentax lens to the filmplane which is 45,46 millimeter.

Your website about your Baader T-ring tells, quote: “Represents the standard exact distance of 55.0mm from the front support surface of the T-ring to the image plane of the camera body forth”

Now, this 55,0mm is longer than the 45,46mm registerdistance from Pentax.
Does the ring still work and let focus?
