Discovered in 1785 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "vF, vS."
The RNGC (Sulentic and Tifft 1973) notes that this is a 14.0 mag galaxy. Their coded description reads E,R,BM,DIFHALO.
IAAC Observer: Lew Gramer, Site classification: rural; Limiting magnitude: 6.9 (zenith); Seeing: 6 of 10 - above average; 20" f/5 Tectron truss-tube dob Newtonian reflector: "Member of the Pegasus I group. An easy object to averted vision, with a hint of an irregular halo to N and S of a brighter, roundish core. Don't confuse this object with the mag 10 star midway between it and n7619, nor with the MUCH more challenging, nearly stellar spindle n7621, nearby to the SW..."
Steve Gottlieb notes: "17.5-inch: fairly bright, small, elongated, bright core, stellar nucleus, very faint extensions ~N-S. Forms a close pair with N7621 2.2' SW. 8-inch: very faint, small.
