Arp 71 (NGC 6045)

  This page is  a bit different from most.  Arp 71 was the first Arp I deliberately imaged and I've accumulated quite a variety of images over several years, because I keep coming back to it.  This is one of the earliest images taken with my SBIG ST2000XM camera.  I was able to fit four Arps into the field and they are all labeled.  This field is a portion of the Hercules Galaxy Cluster. In addition to the Arps, there are six more NGC and two IC galaxies, plus countless others.  Some are extremely unusual, at least as peculiar as any of the four Arps, just a lot smaller.  Because of this, I made the positive image to the left a hyperlink to a full size negative image of this field.  Just click on the image to see it and use your Back button to return to this page.

Arp 71 is in the class Spirals with Small HSB Companions on Arms.  The main companion is obvious at the east end of the primary but there is an additional faint companion on the north edge, seen best in the 2x detail image below.
