Some very nice data from Martin Pugh's CDK17. These are the tiny little galaxies on the edge of M83: PGC 48132, the "big" one and PGC 724525, the smaller one. I'm still working on M83 itself. The data deserves more than a quickie process
Mike Sidonio also featured these little critters back in 2015:
