900/1200mm - 48" (5/12/18): at 610x; fairly faint to moderately bright, fairly small, oval 3:2 WSW-ENE, ~25"x16". This unusual binary AGN displayed two nuclei oriented ~E-W that were cleanly resolved, despite a separation of only 3.8"! The eastern nucleus (Mrk 463E) was noticeably brighter (perhaps by a 2:1 ratio) and had a sharp stellar appearance. The western nucleus was fainter with a softer appearance (quasi-stellar). The common envelope encompassed both nuclei and appeared fairly uniform. The tidal tail to the southwest was not seen. UGC 8850 is located 20' due east of mag 2.7 Eta Boo.
