Discovered in 1785 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "F, pL, irregular figure."
The RNGC (Sulentic and Tifft 1973) notes that this is a 12.5 mag galaxy. Their coded description reads SLEL,BM,HISB.
Steve Coe, using a 13" f/5.6, notes: "Pretty faint, pretty large, little elongated (1.2 X 1) in PA 60 and much brighter in the middle at 100X. There is a 13th mag star about one arc minute to the south."
