Discovered in 1788 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "pB, cL, iF."
Burnham calls it a 13th mag spiral galaxy in Canes Venatici, measuring 1.3' x 0.7' , which he describes as "pretty bright, pretty small, very slightly elongated and gradually a little brighter in the middle."
The RNGC (Sulentic and Tifft 1973) notes that this is a 13.0 mag galaxy. Their coded description reads SLEL,HISB,DKPCH SEND.
