Arp 130

 Arp 130 is another of the class E-like Galaxies Perturbing Spirals.  In this case, the spiral is barred and low surface brightness.  The irregular galaxy in the southwest corner is IC 5377 and the small galaxy almost due south of Arp 130 is IC 5379.

In my opinion, this is the most difficult of all the Arps to image well.  The spiral has a great deal of very fine structure but has extremely low brightness.  For a 10-inch aperture like I have, a good image would require operating at f/10, or more, with a total exposure of 8+ hours.  Adaptive optics would certainly help.
