I decided to process the DSS version again (last image posted was stacked using Nebulosity) the galaxy now spans edge to edge almost.
This time I tried to retain the galactic bulge without blowing out but in doing so some of the core detail is lost in this version. This is a planned
20 hour project, I will post a 10 hour version soon after the moon wanes weather prevailing and I don’t get hit by a bus.
