OK I managed t get a few shots with my qhy10 and 127mm scope.
the first image is the full frame of M42 with the CCD67FR at a total of 101mm from the chip. The next is 127 mm frame and the last is a large magnification of each of the four corners of the CCD67 image.
Hope this helps but so far this looks about the best Ive used on this scope, the Lumicon 2" FR comes a close second while the others are hopeless.
I may have to do a little juggling with the chip distance and to get the stars a little tighter in the corners but its very close.
Hope this helps, Allan
