Planetary Nebula Abell 16


The planetary nebula Abell 14 (PK 153+22.1) 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 first had the number 11 (A55 11). In 1966 Abell published a completed list including the size and description of the 86 planetary nebulae discovered on the POSS photo plates. The PN was then listed as number 16 (A66 16). He described the morphological appearance of the PN as «D» (a homogeneous disk). [331, 332]

The designation PK 153+22.1 originates from the two Czechoslovak astronomers Luboš Perek and Luboš Kohoutek, who in 1967 compiled a catalog of all the planetary nebulae of the Milky Way known at the time. [146]
