1_ is it a coma corrector right after the thin OAG?
2_ What distance do you have from the AOG to the camera face?
Thanks for your help.

1) The Coma corrector is before the OAG.
2) as I said on my picture:
"That now allows me to adjust the
Baader RCC for the correct 91.5mm
distance from the camera sensor to knurled ring or to whatever works best."
You see - the Varilock adjustment sleeve allows me to adjust the distance.
