Discovered in 1787 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "pF, pL, E np-sf, but nearly in the parallel, mbM, 1.5' long."
This 12.6 magnitude spiral galaxy is recorded in the NGC as "pretty bright, pretty small, slightly elongated in 120 , much brighter to the middle."
The RNGC (Sulentic and Tifft 1973) notes that this is a 13.0 mag galaxy. Their coded description reads S,EL,BM,HISBCT SOUTH ARM NOT VIS.
This galaxy appears on page 20 of "The Hubble Atlas of Galaxies" by Allan Sandage (1961, Washington, DC).
