William Herschel discovered NGC 3567 = H III-89 = h836 on 13 Apr 1784 (sweep 191) and logged "eF. I am a little doubtful of the reality. His position is 30 seconds of RA west and 3' north of UGC 6230, the only object in the vicinity. John Herschel made two observations and measured a fairly accurate position, but he was uncertain of the identification with H. III-89 because of the poor match in positions. He also noted "an appearance of stars", perhaps picking up the close companion as stellar!

400/500mm - 18" (3/5/05): fairly faint, round, contains a relatively bright stellar or quasi-stellar nucleus surrounded by a round, faint halo. Forms a double system with MCG +01-29-012 39" SE. The companion appeared very faint, very small, 20" diameter.
