May I clarify an issue with the spacing of the MPCC in relation to the film plane (or plane of the CCD in the QHY8). I attach a snippet from the MMPC blurb from the manufacturer which suggests a distance of 55mm from the imageing chip to the outer rim of the T-Ring. Can this be right? I was having a look at Marc's tech drawings that were the basis of the variable adapter he had made by Peter Tan and started counting diatances again and now I am quite at sea over this whole issue. Can someone clariffy please?
