John Herschel (1847) Cape Observations

This 13th magnitude spiral in Antlia was discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "faint, round, gradually brighter in the middle; 20 arcsec." On a second occasion he called it: "pretty faint, round, very gradually brighter in the middle; 26 arcsec."
