Palomar 6

Palomar 6 is a loose globular cluster in the constellation Ophiuchus that belongs to the Milky Way galaxy. It is a member of the Palomar Globular Clusters group and is located about 25,000 light-years away from the Sun. It formed in what would become the bulge of the Milky Way and is similar to other old-bulge globular clusters such as Messier 62, NGC 6522, NGC 6558, and Haute-Provence 1.
First discovered on the National Geographic Society – Palomar Observatory Sky Survey plates by Robert G. Harrington and Fritz Zwicky,
it was catalogued as a globular cluster, and was thought to be one of four globulars known to contain a planetary nebula. A paper published in 2024, however, showed that the proper motion of the central star of the nebula JaFu 1 differs from that of the cluster with high statistical significance, thus confirming that the nebula is not located within the cluster.
