Type: galaxy (AGN LINER-type), SBc
Mag: B=12.6, V=?
Size: 2.884′ x 1.348′
Discovered in 1787 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "pB, E, BNM and faint branch 2' long, 0.25' broad."
Burnham calls it a 12.4 mag spiral galaxy in Bootes, measuring 2.3' x 0.6', which is considerably bright, pretty large, pretty much elongated and suddenly much brighter in the middle to a nucleus.
The RNGC (Sulentic and Tifft 1973) notes that this is a 12.5 mag galaxy. Their coded description reads S,EL,BM,PD,DKLN.
Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "12.4M; 2.3' x 0.6' extent; faint slash with 13M or dimmer stellar nucleus; 9M star 3' to WNW; 10M star 4' W and a little S; bright yellow-orange star 9' to NW is 6.2M Gloria Ginae (SAO 45445); Lux Lisae (SAO 45440) is the bright (6.5M) blue-white star 50' due N of Gloria Ginae; 2.5' NW of Lux Lisae is 6.5M white star Ignis Iani (SAO 45348)."
Steve Coe, using a 13" f/5.6, notes: "Pretty bright, pretty large, much elongated (3X1) in PA 25, much brighter in the middle with an almost stellar nucleus at 100X."
