Very neatly done. I was browsing your image gallery and noticed your QHY9 setup with the filter wheel and thin OAG/lodestar. Very interested in it. I've been struggling to use a similar setup but I can't seem to get the lodestar to focus and just realised I might have had the OAG too close to the camera face. Couple of questions.
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.
