I have done 2 nights on this. The first night's data was only partly used as it wasn't in focus enough. Also I think flats may help this data. There seems to be very little vignetting so I haven't bothered so far but processing this seem to leave a slight large red hot spot which took a bit to remove.
But last nights was accurate. I probably will do another night on this one as its still a bit noisy. Its 8 hours and 20 minutes so far. I have some Ha I may add as well if its good enough.

Nice shot, it is a difficult object to process, especially getting those arms to come out, without saturating the core.
