Arp 242 (NGC 4676A & B, The Mice)

  Arp 242 is in the class Appearance of Fission.  The Atlas note says "very thin, bright tail from north nucleus which has strong absorption".  The absorption is not visible in my image and I find it hard to detect in the Atlas image, but the tail is certainly obvious.  This pair is a favorite of large aperture visual observers because the impression in the eyepiece is very similar to the image, except the north tail is shorter and the tail curving around to the south is generally not seen.
