Hi,
Last week I managed to capture 14h of Ha data with 20m subs of IC1396. 20m subs really made a difference in dynamic range.
I am very impressed with my Orion Atlas, I just discarded 1 out of 44 subs! Coupled with EQMOD the Atlas is a very solid platform for short focal length telescopes. The only thing that hate about the Atlas is the weight and Alt/Az knobs!!!
I will start capturing SII and OIII soon. Right now I am in the hospital (taking care of my brother but we are leaving tomorrow!!!) and there is no better way to kill time than processing images!
