Planetary Nebula Abell 63
History
This planetary nebula was discovered in 1955 by the American astronomer George Ogden Abell on the photo plates of the Palomar Observatory Sky Survey (POSS). In 1955 he published a first list of 13 globular clusters and the positions of 73 planetary nebulae. The PN was then listed as number 51 (A55 51). In 1966 Abell published a completed list including the size and description of the 86 planetary nebulae discovered on the POSS photo plates. This PN was then listed as nebula 63. [331, 332]
