Arps and Arcturus


Gregg Ruppel
 

Hi all:

Arp 117 consists of IC 982 and 983; just to its south is  Arp 79, made up of NGC 5490 (B and C).  Both lie just about 2 degrees southwest of Arcturus (FOV in this image is about 1 degree wide). Arp describes 117 as "elliptical close to and perturbing spirals" and 79 as "spiral with large HSB companion on arm".  There are a few other background galaxies basking in the glow of Arcturus:

Gregg,

Excellent processing. That bright star right by the galaxy must have been a real challenge.
