There would be no point in having a corrector if the scope did have a resultant flat field. What I've read is that the VC is better for imaging than the VMC, and the VMC is better for visual than the VC, but both scopes can do both tasks well. Just what I've read...
Daniel is right - F/9.75 vs F/9.
Paul - I don't know all the specific batches and what was wrong with each, all I know is the andrews site lists it as "Guan Sheng RC8" (Ritchey-Chretien) 8" f/9 superceeded OTA" I was only aware of two versions, the one you and I bought, and the current version..
