Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "F, vsbM to a star 16th mag; diameter 1' or 1.5'; S.p. the star g Sextantis, which occassioned its being taken by mistake for Halley's comet, and the consequent loss of that comet."
The RNGC (Sulentic and Tifft 1973) notes that this is a 14.0 mag galaxy. Their coded description reads R,DIF,ALMSTELNUC.
