Yes there is a difference between the TS80 Doublet and the Skywatcher ED80. With the Skywatcher you would need the ED80 Pro version ( which has the dual speed Crayford style focuser) and is more expensive, and it is still f7.5. As Dunk has pointed out you would need to find a reducer corrector that worked with it, the one most often sighted is the 0,85 reducer corrector ( so it would go to f6.35. I agree they are cheap as used scopes but the objective in those older ones would need verifying. Imho the build quality of the TS80 and the solid imaging rack and pinion focuser is much better than the Skywatcher offering.
