NGC 2228 is a member of ACO S585 = AGC 3389, which includes NGC 2229, 2230 and 2235, but is situated ~30' N of the core of the cluster.

John Herschel discovered NGC 2228 = h3047 on 31 Jan 1835 and noted "F; R; glbM; 20"." His position (single sweep) matches ESO 087-007 = PGC 18862.

600/800mm - 25" (10/16/17 - OzSky): at 244x; fairly faint, fairly small, round, 30"-36" diameter, very small bright core. At 397x the core seemed elongated ~E-W, but this was due to a mag 15.6 star that occasionally resolved at its east edge. Located 11.6' NW of mag 8.2 HD 45462 (a wide 1.5' pair with a mag 9.9 star).
