Heinrich d'Arrest discovered NGC 6226 on 24 Sep 1862, along with NGC 6223, with the 11-inch refractor at Copenhagen and noted it formed an equilateral triangle with two mag 12/14 stars. His single position is ~40" south of UGC 10532.

400/500mm - 17.5" (6/18/88): fairly faint, fairly small, oval WSW-ENE, weak concentration. A mag 12 star is 1.8' ESE.
