Hi all,


I've been thinking how good some extra focal length would be. Rather than buying a SCT or RC, I was thinking about adding a 2x Powermate to my 1270mm f/5 Newtonian. I have a reducer for my Esprit which gives me 550mm and 375mm from the same OTA and I was think that 1270mm and 2540mm from the Newt would be good (obviously the down side would be f/10). This would be for imaging and not visual. Does anyone have any experience in a similar combination, or perhaps suggestions how to do it better?


Thanks, Kevin
