Looking Inside CTIO Telescopes

Fly above the Main Platform of Cerro Tololo Inter-American Observatory (CTIO) and take a peek inside the open dome slits of the SMARTS 0.9-meter Telescope, the SMARTS 1.5-meter Telescope, and the Víctor M. Blanco 4-meter Telescope. Finally, shift your gaze westward and witness the Sun retreat below the horizon.
