But if you got one. Give it a go and show us! Be interesting to see how much of an aps-c shot is coma free.

I alter the camera-sensor distance to get different amounts of reduction - so my meade f3.3 I use anywhere from 0.7 to 0.33 reduction. I should have some old shots with the meade on a C8 somewhere - using a 1/3" camera.
Ahh, cheers Chris, my bad, Lol
Yes, might be very interesting - and I appreciate your further input on amount of reduction,,, May I ask how much distance the reducer is positioned away from the sensor to achieve a 0.7 reduction and distance for 0.33 reduction, no need be spot on but ball-park-figures would be as useful for this duck If cant, that is all good all the same

I currently have the 10" Newt on my pier, but its being problematic at the moment, Soo, the 12" could be going back on again sooner than later
Cheers
