NGC 7048 is a planetary nebula in the constellation of Cygnus. The bright star to the lower left of the nebula is a magnitude 10.5 star, designated TYC 3589-4652-1. The nebula is slightly brighter along the west and east sides. This planetary nebula has an apparent magnitude of 12.1.[3] NGC 7048 was discovered by Édouard Stephan on 19 October 1878 using a 31.5-inch reflector.[4]

The central star of NGC 7048 is thought to be a white dwarf. The planetary nebula itself has an elliptical shape; from its low surface brightness it is thought to be highly evolved.[5]
