Arp 49 (NGC 5665)

  Arp 49 is the first of Dr. Arp's class Spirals with Small High Surface Brightness (HSB) Companions on Arms.  There are a couple of knots on the east edge which could be companions but it's hard to tell.  I don't find it really obvious on the Atlas image, either.  The note says "appearance of wake from stellar object in E arm" and that does not help much. 

The field size of the combined image was set by the StarlightXpress MX716.
