This was one of my early images, long before I had color capability. Later I took the color data but when I tried to combine the two the luminosity image I'd taken early on didn't match as the film plane wasn't perpendicular to the optical axis so image scale changed from the lower right to the upper left. The color was taken after I fixed the problem. With all the nasty weather I tried again. I broke it up into 6 pieces, matched each then recombined them. It worked rather well but took a lot of time. The large blue galaxy is NGC 7320 is a foreground galaxy not related to the others. It's around 40 million light years distant while the interacting group is some 270 million light years away.
