George Johnstone Stoney or Bindon Stoney, LdR's assistants, discovered NGC 4330 on 14 Apr 1852. During an observation of NGC 4294 and 4299 he mentioned "another vF and thin ray about 30' following." John Herschel catalogued this object as GC 2909 ("R. nova"). Heinrich d'Arrest independently found this galaxy on 15 Apr 1865 with the 11" refractor at Copenhagen and measured an accurate position (3 nights). Dreyer catalogued this observation as GC 5639 with the note ""Probably = [GC] 2909." The two GC entries were combined in the NGC.

400/500mm - 17.5" (4/18/87): faint, fairly large, edge-on SW-NE, even surface brightness. NGC 4353 lies 14' SE.
