Arp 36

  Arp 36 is the Integral Sign galaxy on the west (right) side of the image.  It is also cataloged as UGC 8548.  Dr. Arp's Atlas note says "knots in arms approach appearance of small companions".  The other moderately large galaxy in the field is also an Arp, 183.  They are unrelated and appear on separate fields in the Atlas.  They are close enough to each other to fit within the field of my camera.

I shot three other images the night I shot this pair, and a very large number of the individual exposures had cosmic ray hits on them.  It must have been a very active night a few million years ago, somewhere in the universe.
