Historical observations

William Herschel (c.1784)

Synonyms: H V-041

Discovered in 1786 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "vB, E 60 degrees sp-nf, 20' long, 2' broad."

Published comments

Burnham's Celestial Handbook

Burnham calls it a 10.7 mag spiral galaxy in Canes Venatici, measuring 13.0' x 1.0', which is pretty bright, very large, extremely extended, appears as a narrow streak.

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 10.5 mag galaxy. Their coded description reads EON,LG,B,DIFKN ENDS SOME DKPCHS.

Sandage and Tammann (1975, Astrophysical Journal, 196, 313-328) includes this galaxy in the Canes Venatici I Cloud. Members include NGC 4136, NGC 4150, NGC 4214, NGC 4244, NGC 4248, NGC 4258, NGC 4395, NGC 4449, NGC 4736, NGC 4826 & IC 4182.

G3. CVn I Cloud.

Brightest members: 4736, 4258, 4826, 4449, 4214.

A loose cloud of low-velocity objects may be isolated in the foreground of several more distant, overlapping groups and clouds in the UMa-CVn-Coma area. This whole region is described as the CVn cluster or M94 group by van den Bergh, who points out that many dwarfs are concentrated in this area; Sersic describes a subset as the UMa I group and another as the UMa II group (both of which, however, are all within the boundaries of CVn). ... After much searching and with some hesitation in borderline cases, the following objects were isolated as members of the foreground CVn I cloud (or restricted M94 group): NGC 4136, 4150, 4214, 4244, 4258, 4395, 4736, IC 4182, A1157 (=DDO 115) and possibly NGC 4826. Other possible dwarf members include DDO 99, 125, 126, 129, 133, 141, 143 and 156. All members are spirals of type Sb or later and Magellanic irregulars.

Modern observations

Hartung, E.J. (1968) Astron.Obj.South.Tel

Hartung notes that this "appears as a faint streak of haze about 12' x 1' in pa 45 degrees with a somewhat brighter diffuse elliptical centre. It is barely visible to me with 20cm and like all nebulae the dimensions are more evident by moving the telescope."

Tom Lorenzin

Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "10.7M; 13' x 1' extent; large, soft, NE-SW-oriented slash with no center brightness; !good supernova prospect! see photo at HAG-25."

Contemporary observations

12-inch f/10 SCT (95x/52.8′, 218x/23.1′)

This could be a split image of NGC 4945 in Centaurus. This edge on galaxy in a NE-SW direction displays soft hazy edges and slowly brightens to a large also somewhat elongated nucleus which fades into the soft glow 12" S/C - 218x. Fit in almost two and a half into my 95x field of view, which correspond well with data. Towards the south western tip of the galaxy three faint stars string away.

Observing site: Pinnacles overlook

Telescope: C-8

[12h 17m 30s, 37 49m 0s] A faint streak in the sky, with almost uniform brightness throughout. It was slightly brighter towards the middle, but not nearly as much so as other spirals. The nucleus is hardly visible.
