History

The planetary nebula Abell 80 (PN A55 66, PN A66 80, PK 102-5.1) was discovered in 1955 by the American astronomer George Ogden Abell on the photo plates of the Palomar Observatory Sky Survey (POSS). In 1966 he published a list of a total of 86 planetary nebulae discovered on the POSS photo plates. Most of these 86 PNs discovered on the POSS photo plates are large and have a low surface brightness, which suggests that their stage of development is advanced. [331, 332]

Physical Properties

The PN is at a distance of 1752 pc. Visual brightness is not given in either Simbad or NED. SkySafari 6 gives 6 mag for this. [160]
