Discovered in 1785 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "pF, pS, iF, bM."
The RNGC (Sulentic and Tifft 1973) notes that this is a 14.0 mag galaxy. Their coded description reads R,BM,HISB.
Steve Coe, using a 13" f/5.6, notes: "Pretty bright, pretty small, elongated 1.5 X 1 in PA 135 and has a bright middle at 100X. The listed magnitude for this object is 13.9, I would estimate it to be 12.8 visually."
