Sorry for any confusion here, it's the Skywatcher black diamond ED100 with a soon to be acquired .85x FF/FR. It'd be lovely to have a f5.5 Triplet! My reason for picking up an Skywatcher f9 ED 100 was mainly for visual use on the moon and planets, to replace my f5 Skywatcher ST120, which shows quite a bit of CA although fun to use for grab and go galaxy hunting. Just wondered where it would stack up photographically. Have a good picture of that now :-) Am planning to try the Newt and ED100 out sequentially as soon as time and clouds allow.
So, to be clear, a shorter focal length but high quality 100mm refractor on a good mount CAN get more photographic detail and resolution than a lesser quality but longer focal length 100m refractor and be the equal of an 8" Newt? Aperture and good glass can increase contrast and the focal length isn't such a factor in detail, or at least not with these scopes? I had figured the focal length of the ED80 would limit its ability to capture fine detail no matter how long the exposure or number of subs?
