IC 5305 is faint, very small, round, 15" diameter, weak concentration. Located 3.8' NNE of a mag 11.5 star and 1.9' W of NGC 7594. Collinear with two mag 14 stars 45" SSW and 1.4' SSW.
IC 5306 is extremely faint and small, round, 15" diameter, low surface brightness. Collinear with IC 5305 3.4' NNW and two mag 14 stars 2.0' NNW and 2.7' NNW.
IC 5307 is extremely faint and small, round, 15" diameter. Faintest of four in NGC 7594 group and required averted to glimpse.
Guillaume Bigourdan found IC 1478 = Big. 239 on 22 Aug 1889. His position matches UGC 12485 = PGC 70991. This galaxy was originally discovered by Common in August 1880, but his position (estimated using setting circles) is 6' too far southeast. All modern galaxy catalogues (as well as HyperLeda) identify this galaxy as IC 1478.
400/500mm - 17.5" (11/18/95): faint, small, elongated 2:1 ~N-S, 0.8'x0.4', broad weak concentration. The outer halo increases in size with averted vision. Brightest in a quartet (WBL 706) with IC's 5305, 5306, 5307. NGC 7594 is identified as IC 1478 in UGC, MCG, CGCG and RC3.
