Canon EF Mount to M65 Paracorr

thingiverse

This is a simple Canon EF Mount to M65 threaded adapter. This is to connect a Canon DSLR camera to a Tele Vue Paracorr. The paracorr uses an M65 thread connection and this has an extra 12mm spacing added to bring the camera to the 56mm focal point of the paracorr. My main change to the EF mount was to put the cube nub on the side where the lens release button is since that's easier for me to feel/see at night. This can be adjusted in the .scad file quite easily by changing the rotation. This is meant to replace [this adapter](https://agenaastro.com/tele-vue-canon-wide-t-adapter-w-bayonet-for-2-4-cwt2070.html). This is a remix from https://www.thingiverse.com/thing:398515 Edit: 1/27/21 I received the paracorr today and the adapter seems to work right out of the box. I didn't have time to take any type of proper pictures but I was able to get focus with a Bahtinov mask and the few pictures I did take seemed pretty decent without any sort of tracking.
