ARP 270 and friends

I am fascinated by the work of Halton Arp who studied unusual galaxies and this image was taken to capture NGC 3395 and 3396, an interacting pair also know as ARP 270. They are in Leo minor and about 85M light years distant and quite small targets 2.1x1.2 and 3x1.2 arc min respectively with magnitudes around 12.5. It was possible to capture 4 other galaxies in the same field. They are NGC 3413, 3424 and 3430 and IC2608.
