Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "bright, large, much elongated, gradually a little brighter in the middle, 90 arcseconds long, 25 arcseconds broad." His second observation was recorded as "faint, much elongated, very gradually brighter in the middle, 25 arcseconds." His final observation was recorded as "faint, much elongated in pos 147 ; very slightly brighter in the middle; 2' long. Taken beyond the meridian, and out of reach in RA."
Burnham calls this a 12.5 mag barred spiral galaxy in Centaurus, 2.3' x 0.7', faint, pretty large, much elongated and very gradually brighter in the middle.
