NGC 4801
Discovered (Apr 26, 1789) by William Herschel
NGC 4802 (= NGC 4804)
Discovered (Mar 27, 1786) by William Herschel (and later listed as NGC 4804)
Discovered (Apr 20, 1882) by Wilhelm Tempel (V-21) (and later listed as NGC 4802)
An 11th-magnitude lenticular galaxy (type S0) in Corvus (RA 12 55 49.6, Dec -12 03 17)
The second IC adds "Not found by Howe (one night). The description agrees with that of 4804, exactly 1 degree south. Tempel says it is 8 seconds following Lamont 1234 (10th magnitude), but this identification may be wrong".

NGC 4826 (= M64), the Black Eye Galaxy
Discovered (Mar 23, 1779) by Edward Pigott
Observed (Mar 1, 1780) by Charles Messier, and listed as M64
A 9th-magnitude spiral galaxy (type Sab) in Coma Berenices (RA 12 56 43.8, Dec +21 40 59)
Recent studies of this galaxy show that although the stars and gas in its central structure are moving in the direction expected from its spiral appearance (clockwise, in the views shown below), the gas in its outer regions is moving in the opposite direction. This is probably the result of a collision and subsequent merger with a smaller galaxy, a billion or so years ago; but whatever the reason, collisions of clouds of gas and dust within the boundary between the two regions have led to a chaotic burst of star formation, giving the core of the galaxy an unusually dramatic appearance. |
