I have had a quick look at some old threads and wondered if some of the problems arising with this combo were solved- namely the fact that the baader mpcc people advise the back distance to sensor is 55mm so the coma corrector should be attached directly to the dslr etc
But then the thin oag such as Ts Oag-9 adds 9mm plus probable 3.5mm spacer to the mix and is supposed to go between the two?
Anybody solve this issue satisfactorily and can help me out ?
Is the space not that critical? At f4 I would have thought so, so need advice.
Thanks
