Discovered in 1784 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "pB, pL, not R, bM, r."
The RNGC (Sulentic and Tifft 1973) notes that this is a 12.5 mag galaxy. Their coded description reads S,R,BM,PCHSTRPERIPH F OUTER ARMS.
This galaxy appears on page 30 of "The Hubble Atlas of Galaxies" by Allan Sandage (1961, Washington, DC).

Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.9M; 2.2' x 1.3' extent; fairly bright oblong with brighter center and 13.5M stellar core; axis oriented WNW-ESE; see photo at HAG-30; 7.5M star 12' E and a little S is SAO 01654."
Steve Coe, observing with a 13" f/5.6, notes: "Pretty faint, pretty large, elongated, brighter in the middle, stellar nucleus at 165X. Averted vision makes it grow in size."
