Discovered in 1785 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "vB, S, R, vsmbM."
Burnham calls it a 12.6 mag elliptical galaxy in Bootes, measuring 0.9' by 0.8' which is suddenly much brighter in the middle, considerably bright, small and slightly elongated.
The RNGC (Sulentic and Tifft 1973) notes that this is a 13.0 mag galaxy. Their coded description reads E,R,BM.
Steve Coe, using a 13" f/5.6, notes: "Pretty bright, pretty large, little elongated 1.5 X 1 in PA 90 and much brighter in the middle with an almost stellar nucleus at 165X."
Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.3M; 1.3' diameter; soft round glow with brighter, almost stellar nucleus 5' ESE of an 11M star; 1 degree S and a bit E is 5M SAO 64053; 25' WSW of star is SP GAL N5533 (12M; 2.5'x 1.5' extent)."
