I concentrated on the disk detail Mike - there is no halo worth looking at with 80 minutes of 20 second subs and limited stretching (not much of any background stuff actually). In the earlier version, a lot of poorer res data was included to get an image of the halo and the background galaxies. Maybe I should try for some more data.
This is the sort of thing I was trying to get part of the way to:
