Well, thats a strange one Peter.
I have the spacing correct (55mm as far as i can see) and i get shocking coma. I have been in touch with Peter Lee over this in HK, as he sells a MPCC to QHY8 adaptor thats "back focus matched" so i would assume this to mean that, the adaptor will put the focus behind the MPCC exactly where its supposed to be.
Cost of the adaptor is $50 posted
