soon I am going to get a second system running - a 12" Astrograph from ASA on a DDM60 mount - and I am struggling to get my imaging train fit into the backfocus. I'd like to go for a Moravian G3-16200 camera, but I also want an OAG. And here the mess begins:
According to Moravian, their normal setup would require 62.5mm of backfocus, but the Wynne corrector only allows for 58.25mm.
Alright, now there would be a particular OAG for theor G4 cameras which is made explicitely to attach the setup directly to ASA's Wynne corrector - but this only works on G4 cameras and no others
I also considered other OAG's, like some of Teleskop Express, but they all require more or less adapters which, in turn, eat up the backfocus. I was wondering if somebody here is using Moravian CCD's with an OAG and how they solved this situation.
