Ordering it now. Just working out the spacers and compression rings as it has to go from M48 to M42 for the QHY8. I reckon it's gonna rain for another 2 extra weeks now...
Spacing is 97.5mm from the base of the M48 male thread. So counting the back adaptor ring on the C11 cell that puts the camera in the vicinity of 110mm which is the "ideal" back focus. Although this ideal back focus has been argued not to make any difference in image quality within a range from 96mm up to even 157mm. Can't wait to see the results now. The edge stars will still be chonky of course to some extent but much smaller chonky size so easier to "hide" or round at processing time
