Corwin's Notes

===== NGC 7475 is one of the brightest galaxies in a poor cluster. It was found by Marth in August of 1864; NGC 7474 is another in the cluster that he found on the same night. In previous NGC lists, I had the companion of the brighter galaxy listed as a part of the NGC object. However, Marth makes no mention of duplicity of his object, and I think it is likely that he saw only the brighter object. So this time around, I've split them up to reflect this.

Steve's Notes

===== NGC 7475 24" (9/10/15): at 260x; fairly faint to moderately bright, fairly small, elongated 3:2 or 4:3 WSW-ENE, ~0.6'x0.4', contains a very small bright nucleus that appears offset to the southwest side. NGC 7474 lies 1.6' SE. A mag 11.5 star lies 1.7' NW. With careful viewing this is clearly seen as a double system with a companion attached at the northeast end (MCG +03-58-028 = PGC 70382). It was visible as a faint, small, round glow, 12" in diameter. The centers of the galaxies are separated by just 27" and nearly collinear with NGC 7474. 17.5" (9/2/89): faint, fairly small, elongated SW-NE. A mag 11 star is 1.7' NW. Forms a pair with NGC 7474 1.5' SW. The compact companion at the NE end was unresolved.
