NGC 68 galaxy group (Arp 113)
 

 

 

The NGC 68 galaxy group (or Arp 113) is a distant (300 millions light years) cluster of at least 40 galaxies (including 4 large and 5 smaller NGC members) around the elliptical galaxy NGC 68.

Nice large spirals NGC 70 and barred NGC 72 make the view even more interesting (and, to my surprise, some details of the galaxies were resolved even with my relatively small scope).

Later I tried to reprocess and (slightly) enlarge the picture to show the details of the galaxies more clearly, see below..
