IC 504 is the brightest of a group of 7 galaxies (WBL 179) including CGCG 032-009 4' N, IC 506 12.5' ENE and IC 505 12' NE. But the redshift of IC 504, along with CGCG 032-012, is half the remaining members so there appears to be two superposed groups at different distances.

CGCG 032-012, 4.7' ENE, appeared fairly faint, very small, round, 15"-18" diameter. A mag 11.9 star is 40" SW, the first in a chain extending to IC 504.

CGCG 032-009, 4.0' N, appeared as a faint soft glow, 18", fairly smooth surface brightness.

CGCG 032-013, 8.5' NNE, appeared faint, small, elongated 5:2 SW-NE, 25"x10".

CGCG 032-011, 7' SE, appeared faint, small, roundish, 15" diameter. A mag 13.8 star is at the south edge.

Lewis Swift discovered IC 504 = Sw. VII-11, along with IC 505 and 506, on 8 Mar 1888 and recorded "vF; pS; R; nr. p end of 4 st. in an arc of a circle. 1st of 3." His RA is ~10 seconds too small, but the identification is certain as the description is a perfect match.

600/800mm - 24" (2/8/18): at 375x; fairly faint or moderately bright, fairly small, slightly elongated NW-SE, 0.5'x0.4'. Contains a relatively large bright core with a fairly thin halo. A mag 11.0 star is 1' SE, the first in an equally spaced looping chain of 4 stars that leads directly to CGCG 032-012, 4.7' ENE. The surrounding star field in general is pretty rich.
