Nice detail visible oin the arms, thats one on my list to get over the next few months. I think maybe a longer exposure is needed to get rid of the graininess?

Dave, more frames will improve the S/N ratio, longer exposures would probably only make it worse.


Anyway I've done a reprocess of this, I like it more but I'm interested to see what others think.
