Discovered in 1786 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "cB, R, psmbM."
Observed by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "B, pS, R, psbM, 12 arcseconds, a star 9th mag follows 10.5 seconds." On a second occassion he called it "vB, R, bM, has a star 10th mag 11 seconds following, 30 arcseconds south."

Hartung notes: "In a field sprinkled with stars is a bright symmetrical nebula about 1.5' across with a nuclear centre. 10.5cm shows this object plainly and also the nucleus; the small star 2.5' following is a close pair."
Steve Coe, observing with a 17.5" f/4.5 at 100X, notes: "Pretty bright, pretty small, round, very suddenly much brighter in the middle with an almost stellar nucleus at 150X.
Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.7M; 1.3' x 1' extent; bright, small oblong with much brighter center; 7M star 2.5' to E."

Just under 4° due south of 3rd-mag gamma Hydrae lies this comet-like galaxy. 60x, 120x: An obvious round glow, brighter in the middle. Sketch. A small star lies close (0.7-arcmin) ENE, while a bright orange star is further ESE (HD 115560, V=9.0, B-V=+0.54; 2.3-arcmin away). (D: 20090129/30. Own star charts)
