History and Accurate Positions for the NGC/IC Objects (Corwin 2004)

NGC 5494 appears in Swift's big 11th AN list of new nebulae. Dreyer caught this, so Swift's rediscovery was not given an IC number. See IC 2595 for more about the nebulae that Swift found on the night of 22 February 1898.

Discovered by John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "pretty bright, large, round, gradually brighter in the middle, resolvable. Stars barely seen in the nebula, besides several others about it."
