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

The bright star near NGC 6441 is G Sco.
Indicated and visible in the image, very close to the star, is also the faint
planetary nebula Haro 1-36 or Henize 2-289 (PK 353-4.1, PN G353.5-04.9),
an almost stellar object of about visual mag 12.1.
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).
