History

This galaxy was discovered by William Herschel on 5 February 1788. He listed it as «faint nebula» II 730 and noted: «Pretty bright, brighter in the middle, resolvable, 4' long, 3' broad.» [464] John Herschel made two observations and listed it as h 910. His first note on sweep 329: «Pretty bright; very large; extended in meridian; very gradually brighter in the middle; 4' long, 2' broad; has a star at its northern extremity.» [466]
