Discovered in 1786 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "Two; the preceding [NGC 5574] pB, pL, E, distance 3' or 4' sp-nf. The following [NGC 5576] cB, R, pL."
The RNGC (Sulentic and Tifft 1973) notes that this is a 12.0 mag galaxy. Their coded description reads E,R,BM.
Van den Bergh (1961, Astronomical Journal, Vol 66, p566) notes that this galaxy forms a pure pair with NGC 5574 2.8 arcminutes away.
Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.9M; 2' x 1' extent; small oblong with much brighter center; 13M star 1.5' NW of core; try to see 13.4M SP GAL N5574 (55" x 20") very faint slash 3' to SW; brighter, larger SP GAL 5566 is 40' N and a little W."
Steve Coe, observing with a 13" f/5.6, notes: "Pretty bright, pretty large, much brighter middle, round at 100X. The companion is pretty bright, pretty small and elongated, it is 5 arcmin to the SW of 5576."
