Historical observations
William Herschel (c.1784)
Synonyms: H II-131, H IV-006
Discovered on the night of 23 February 1782 by William Herschel with an 18.7-inch f/13 speculum telescope. He logged it as IV-6, describing it as "Faint, large, cometic. A central bright point with an extremely faint milky chevelure." On the night of 13 April 1784, he recorded it as II-131, writing "pB, vL, nearly R, lbM." Dreyer noted: "II-131 is the same as IV-6. Five obs. by H., who never saw more than one nebula..."

Modern observations
Steve Coe
Steve Coe, observing with a 13" f/5.6, notes: "Pretty bright, large, round, much brighter in the middle and quite mottled at 220X. Averted vision makes this face-on galaxy grow in size."
Tom Lorenzin
Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.7M; 3.5' x 3' extent; faint glow; not quite round with little brighter center; !good supernova prospect!."
