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, 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).
