Not much noise in my full res shot and I cannot see any in the posted image, so not sure where you can see it. Adding more data tonight as I did a heap last night on M66 and M65 but that was not really worth the effort. With tonight I think that will be enough and I will have to wait until my new OIII (3nm) and SII (5nm) filters arrive from Astrodon to do much more to this image in moon light.
Ok...you still have trouble interpreting my posts huh?... I was being flippant Yes the stars are slightly elongated in places but I knew why and of course there is next to no noise but you always seem to be able to find some all good fun ...sorry, I ain't gunna change, not for you not for no one If you can drag me down the mega data road, well, I'm going to drag you down the light hearted have a lend post road
