Type: galaxy, S...
Mag: B=12.27, V=11.14
Size: 3.311′ x 2.29′
Discovered by John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "bright, round, very gradually little brighter in the middle; 45 arcseconds; has three 14th mag stars near." On a second occasion he described it as "bright, pretty large, slightly elongated, gradually a little brighter in the middle, resolvable, three very small stars nearby."
The NGC calls it "bright, pretty large, slightly elongated, very gradually a little brighter towards the centre, three stars nearby."
Burnham calls this a 12.8 mag spiral galaxy in Centaurus, 1.5' x 1', bright, pretty large, very slightly elongated, very gradually a little brighter in the middle.

It can be found easily, since it forms the tip of an isosceles triangle with two stars shown on the U2000 chart. As seen with the 15.5" telescope, it is a moderately faint object, lying amongst a halo of bright stars. The galaxy shows as a bright core surrounded by nebulosity. To the south lies two faint stars on a northwest- southeast diagonal, and to the immediate southeast lies a third, fainter star.
Sky Conditions:The fainter parts of the Milky Way are barely visible.Haziness only visible on the horizon.Atmosphere stable with little interference.
This galaxy has a slightly oval shape which looks like an out focus peanut and that this galaxy is well defined as a very faint smudge of light being seen at 75x.The central nucleus of this galaxy is relatively compact.This galaxy measures 3.1'x 2.5'with P.A:ESE/WNW.
