For those of you that have successfully used a Ricarrdi specifically the small M63 can you tell me what back focus you use in your success?

I am working with Markus and that he doesn’t have a back focus —he has heard of success but is reluctant to give a specific backfocus because he doesn’t have a definitive guarantee that it will work.

I have read in places that it will work but don’t have more details besides “it works “. I would be happy to share Pictures and more once I do get a backfocus nailed but I kind of need to know where to start I was able to get Starizona to manufacture a custom adapter for me because I want to be able to use my William optics rotator so I will basically have a riccardi reducer adapter on one side to Allow insertion into the focus her and then a female m 63 to allow my William optics rotator to screw in

I don’t rotate my Moonlite.

Thank you in advance.

Dawn

The backfocus is 86.5mm but there is a flange that takes up 13.5mm so you need to be exactly 73mm from the end.  This is for a 250mm RC.  The reducer needs to be very close to the back of the scope so I ended up embedding it into a Feathertouch focuser.  This has the added benefit of not hanging your camera off the reducer itself.

This was with the m63 too correct? I don’t know the flange t
You are referring too but the 86.5 Will help us a starting point because I’m assuming I would be close to that too at 1600mm
