Hi Everyone
Thanks for the positive comments. It's great to get feedback from my learned colleagues.
Paul,
I think I love the MPCC. I'm having discussions at the moment with a bloke from the LXD55 group. He has apparently done some ray tracing with the MPCC and the Meade SN scopes. Apparently there is some slight over correction resulting in minor spherical aberations in the centre and also some minor chromatic abberation. He says that the corrector to camera distance can be changed to minimise "residual coma", but he hasn't given me the corrected distance yet. I'll let you know when I know.
All I really know at this point is that my images are much better with the MPCC than without it, so far!
Cheers
