Zwo ASI585mc > Takumar 200mm F/4

[brenski]

Looking to see if it's possible to connect a Zwo ASI585mc to a Takumar 200mm F/4 (M42 thread)

At present I've used a combination of the various connectors I have and infinity is nowhere near correct. Looks like a backfocus issue.

Has anybody done this successfully using the 2" ring connector?
if so, what connector/spacer did you use? how did you do it

I have only ever connected a Canon lens to my ASI294MC and that worked well.

What back focus are you getting with the Takumar and the ASI585MC?
