Discovered by James Dunlop on May 13, 1826.

This globular cluster was discovered by James Dunlop from Paramatta, Australia in 1826 and cataloged as Dunlop 557 (or Dun 557).

The image in this page was obtained by Martin Germano. The bright star near NGC 6441 is G Sco. Indicated and visible in the image is also the faint planetary nebula PK 353-4.1, very close to the star.

NGC 6441 is one of only four known globular clusters which currently homes a planetary nebula. This planetary was not discovered until 1997, as it is hiding near the multitude of stars of globular cluster Palomar 6 (Jacoby et.al. 1997).
