Arp 139 is another of the class Material Emanating from E Galaxy. It is
the group a bit west of the center of the field. The other bright galaxy,
E and a little N of Arp 139, is CGCG 160-144. Arp 139 does not show a lot of
detail, either in my image or in the Atlas.
3x detail shows a little more, but not much.
