Discovered in 1786 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "pB, pL, iR, vgmbM."
This 12.5 magnitude elliptical galaxy is recorded in the NGC as "pretty bright, small, very slightly elongated, very gradually much brighter to the middle, star 12th mag preceding."
The RNGC (Sulentic and Tifft 1973) notes that this is a 12.5 mag galaxy. Their coded description reads SO),R,DIF,SBM.
Steve Coe, using a 17.5" f/4.5, notes: "Pretty faint, pretty small, round with a brighter middle at 135X."
