Hi
better late than never I guess. love how the background galaxies show through so brightly in the dim parts of the halo.

the colour image has not been stretched enough to show the deepest detail, but, with 4x4 software binning and inverting, the loop that Paul mentioned can be seen to the lower right (also visible in the AAT image and Mike's 2012 deep image also shows it)

With the binning, this image gets down to about 26 vmag/arcsec2. Clearly need to do some work on my flat fielding at this depth and the stars look as though I need to clean the mirrors as well - or maybe it was just atmospheric haze on one of the nights that caused the close scatter
thanks for looking. regards Ray
