canon eos to 2" telescope

thingiverse

I designed an adapter to use my Canon EOS 20D with a Dobson Kepler 254/1250 GSO telescope. Several other designs were attempted but failed due to issues with minimal distance between telescope and camera: focus could not be set on the camera sensor, while others resulted in excessive backlash on either the EOS 20D or the telescope, or both. This adapter fits my camera perfectly and is designed to minimize the distance between camera and telescope. I will try it tonight and hopefully achieve focus. Edit: Unfortunately, this design also failed to achieve focus. A reducer corrector for my EOS 20D is required. However, this adapter represents the best possible solution given the limitations of my camera, which cannot be positioned closer to the telescope.
