Arp 311 (IC 1258, 59, & 60)
Arp 311 is the first member of the class Galaxy Groups. The pair NNE of
center is Arp 310, also IC 1259. The galaxy right in the center of
the field is IC 1258. About 2' ESE is IC 1260. The last galaxy in
the Atlas field is the very small one making up the E corner of a box with the others; it is in the SDSS catalog. Note the faint bridge of material
between Arp 310 and IC 1258.
There are a number of other decent size galaxies in the field, but as far as I can tell, none are included in more widely used catalogs than SDSS, 2MASX, MAC, or NPM1G.
