I have purchased a 135 MM F2 Samyang lens and plan to send it to Ron at Moonlight to add his belt focus motor assembly.
It will be piggy backed on a long focal length scope at a remote dark site.
I will be using it with a QHY OAG M and a ZWO asi 1600 C one shot color camera. I have very limited back focus with with the Precise Parts Nikon to 54 mm adapter so I don't have much room (maybe 3 mm) for a UV/IR filter.
I have a 77mm UV/IR filter for the front of the lens and likely will use it there . Any ideas on something better?
