Omega Centauri

Picture
NGC 5193 in Centaurus

also designated ω Cen and Caldwell 80 is the largest-known globular cluster in the Milky Way.
'Omega Cen' was first  discovered by Ptolemy, and is located at a distance of 17,000 light-years.
With a diameter of roughly 150 light-years, it is estimated to contain approximately 10,000,000 stars!
The average distance between the tightly-packed stars in the cluster is only 0.1 light-year. 
 Omega Cen differs from other globular clusters, as it's thought to have once been the core of a dwarf galaxy.

Note the wonderful IFN (Integrated Flux Nebulae) near the top-left corner of the field of view,
and the sweet, 'little' spiral, ESO 269-85 at 3 o'clock.
