It's early days getting my ASI 294MC Pro cam working with my 200mm F/4 reflector but something I have noticed is that simply screwing my Baader MPCC III coma corrector to the nose of the cam (into the low profile ring it comes with) and sliding into a couple of stacked extension tubes into the focusser, while it achieves focus, does not seem to resolve coma at the edges - like it did when attached to my Canon SLR previously.

This seems to be due to where in the image train I'm placing it. Short of trying just about every combination of adapters and tubes I have, has anyone got a similar setup and what did they find ?

cheers,
