This is a remarkable group of galaxies, with the central barred region of NGC5101 looking almost like it was overlaid onto a quite different outer disk - and the interacting dusty NGC5078 and IC879. There is also an amazing variety of background fuzzies - a significant proportion of the background objects are non-stellar.

This is about as dim as I can get to from this site - really need darker sky
. The outer disk of NGC5101 is only about 24mag/arcsec2, which is really pushing it when the sky is somewhere round mag20.
thanks for looking. regards Ray
