Troy,
hmmmmm, the finicky side says yes perhaps, but the realist in me didn't see too much to complain about, mind you the cracking M42 shot took my eye away from the corners.
A while back I bought an 80mm triplet, famous one too, very expensive. It requires, nay demands, a field flattener, and the usual/accepted fix is the Televue 0.8x reducer/flatenner. Price one and see why I winced. I tried my Baader MPCC and it works. Yes, I still went ahead and got the Televue, but the key to this that the TV one gives me a shorter (0.8x shorter) focal length, something I sometimes want, sometimes I don't. The MPCC doesn't change the focal length.
What am I suggesting here? Try an MPCC if you can, they are common enough that you could possibly borrow one. But like any of them it MUST be at the correct spacing to achieve what you ask of it, and in my case this necessitated a specific, custom made, adaptor.
