Historical observations

William Herschel

In the Appendix to the 1912 'Scientific Papers of Sir William Herschel' this object is described as "1784, March 14. Two resolvable nebulae; the preceding is the largest, and with 157 power seems to have another small nebula joining to it, but with 240 power it appears to be a star. The following nebula is II.55."

Webb, T.W

In the 5th edition of Webb's Celestial Objects for Common Telescopes it is described as "Fair specimen of the many nebulae in this region; midway from 24 to 11, the nearest bright star preceding, a little south. d'Arrest, fainter neb. Following."

Published comments


A supernova erupted in this galaxy in 1960 (11.5p)

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 10.5 mag galaxy. Their coded description reads BE,SLEL,BM,DIFHALO DKPCHS SUSP HALO.

Sandage, A. et al. (1975) Galaxies and the Universe

G. de Vaucouleurs ("Galaxies and the Universe", Chapter 14 - Nearby Groups of Galaxies) notes that the five brightest members of the Virgo I (E) group are NGC 4472, NGC 4649, NGC 4486, NGC 4382 & NGC 4374.

Modern observations

Hartung, E.J. (1968)

Hartung notes that this "is a conspicuous hazy ellipse with faint envelope about 3' x 2' in pa 25 deg, the central parts much brighter . . it is easy with 7.5cm."

Tom Lorenzin

Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "10M; 5' x 4' extent; bright, featureless oval with condensed nucleus; 12M star 1' NNE of core; faint oval SP GAL N4394 (12.2M; 3'x 2' extent) is 8' E and a little N; see photo at HAG-47; SP GAL N4293 (11.7M; 4'x 1.5' extent) 1 degree WNW with axis oriented E-W; good supernova prospects."

Observing site: Pinnacles overlook

Telescope: C-11

[12h 25m 24s, 18 11m 0s] AKA M85. M85 is a tilted spiral with a mottled disc. Looks like an Sc. (Burnham: S0a). N 4394 is another spiral galaxy 3' E of M85.

Sky Conditions:The fainter parts of the Milky Way are barely visible.Haziness only visible on the horizon.Atmosphere stable with little interference.

Instrument:12-inch Dobsonian.

This galaxy is seen as a circular smudge of light with a fairly bright nucleus which is centrally concentrated.Around the outskirts of this galaxy there are some areas of uneven brightness.This galaxy is 3.1'* 1'.The nucleus of this galaxy is slightly brighter compared to the far outskirts of this galaxy.
