M17 (Omega Nebula) in Ha - 4 hrs x 20min subs. This is a wip as I still need to get the S2 & O3 data for a colour image when the skies clear over Melbourne again.
For this standalone image, I pushed the data really hard to see what's around the DSO, ie: shockfronts, dust etc. Seems that the dynamic range of this thing is enormous!
Lots of interesting stuff going on there, but due to the extreme stretch you may not want to pixel peep too closely!
