Discovered in 1787 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "eF, E np-sf, 2' long, 1' broad."
Recorded in the NGC as "very faint, considerably large, elongated PA 124 , vert gradually brighter in the middle."
The RNGC (Sulentic and Tifft 1973) notes that this is a 12.5 mag galaxy. Their coded description reads S,SLEL,BM,SLDIF,DLNS.
F, 2.5'x1.5', E 120deg, spiral, with alm. stell. N. consisting of two oval rings, the n.p. portion of the outer one being absorbed.
Steve Coe, using a 17.5" f/4.5, notes: "Faint, pretty small, elongated 2X1 and somewhat brighter in the middle at 100X."
