Again, very impressive to see such quality at 2000mm focal length. My understanding is that the Meade ACF optics and their 6.3 focal reducer are "incompatible" - the reducer tries to flatten an already "flat" field.
There is little info on the web about what reducer to use with corrected SCTs - I think the optec next-gen reducer is meant to work, or there is an Astrophysics reducer.
