Hi Maurice,
quite a good image considering that it's from
the light polluted suburbs of Melbourne with a colour camera
and on a dim Mag 11 target.
With 2 or 3 hours more careful processing you may have been
able to obtain an extra 10 to 20% out of the image in
the high noise areas.
By splitting the channels -
the blue channel had the most background noise.
cheers
Allan
