Arp 171

Dan Crowson
 

Arp 171 consists of NGC 5718 (UGC 9459 and others) at the center interacting with IC 1042 (UGC 9457 and others) above and to the right. Located approximately 390 million light-years away in Virgo, these are in Arp’s ‘Galaxies with diffuse counter-tails’ class. I’m not sure if he was talking about the faint plumes to the bottom left or something else.

 

Luminance – 24x600s – 240 minutes – binned 1x1

RGB – 8x300s – 40 minutes each – binned 2x2
