Arp 240 (NGC 5257 & 8)

  Arp 240 is another very attractive pair, and in the class Appearance of Fission.  There was no Atlas note.  NGC 5257 is the right hand galaxy while the one on the left is NGC 5258.  The details near the galaxy cores can be seen better in this image than in the Atlas image, as this was another case where the contrast was too strong in the Atlas processing -- it was similar to my negative image.
