Historical observations
John Herschel
Discovered by John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "pretty bright, pretty small, round, gradually brighter in the middle; 15 arcseconds; in a curve of 3 or 4 stars." During the next sweep, he recorded it as "pretty bright, round, small, pretty gradually brighter in the middle; 12 arcseconds. In the middle of an arc of four stars." His final observation reads: "pretty faint, small, round. The middle object in an arc of stars."

Location:Perdeberg.
Time:1:25am.
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 has the shape of an out of focus marble which is circular in appearance and this galaxy is seen as a vey faint smudge of light at both 57x and 75x.The central nucleus of this galaxy is very condensed and that this galaxy has a soft gently glow of grey-white light.This galaxy measures 3.8'x 3.1'.
