The repro is better but would appreciate comment.
I cropped and changed the framing think it helps too.
8" Newtonian astrograph f/4. on Heq pro 5 mount. Orion mini guider.
Unmodded canon 1100D, baader coma corrector, cooler box.
41 x 8 minute subs,
Median stack in DSS, processed in PS7.
Cheers.
Justin.
