47 Tucanae by Damian Peach

Submitted by Planewave Instruments

CDK20″ @ F4.5. FLI camera. RGB: 45mins.

Possibly the finest globular cluster in the entire sky. Visible to the naked eye alongside the Small Magellanic Cloud, the massive ball of stars is 16,700 light years away from our solar system and is 120 light years in diameter. Unlike Omega Centauri (the skies bright cluster of this type) 47 Tucanae is much denser toward the core giving the cluster a “3D” appearance in the telescope.
