Thank you for the data! You may be right that I saw NGC 550, but I thought I
was looking in the area of the unlabeled galaxy shown on Skyatlas 2000,
which is directly north. If I knew there were three to five galaxies around
there I would have been more careful. I was using my 14.5 inch Teleport,
which was showing all five members of Stephan's Quintet and other galaxies
up to about mag 14. Next time I'll stick to Uranometria.

To the NE of NGC's 531 and 533 is NGC 550. This one is brighter and
larger than the IC galaxies you mentioned and the core is fairly
prominent, so I think it's more likely to have been noticed.
