An RC is not a SCT, nor is a corrected DK. A newtonian would struggle to illuminate the full field of a large chip and suffers from coma (yes can be corrected). Not sure how a small RC (i.e 200mm) would fare and would probaly go for the refractor. That said a better mount could never hurt your chances of producing a decent raw image.
