Here's Arp 302 (VV 340, UGC 9618). It's nicknamed the Exclamation Point Galaxy (see this image for a reference). It's a pair of spiral galaxies that are just about to interact with each other.

This is a screenshot:

To "install" this mini add-on, just copy-paste the following code into a .DSC file in your "extras" folder:

{
   Type "Sc"

}
