Sunset Over Cerro Tololo Timelapse

Experience sunset at the Main Platform of Cerro Tololo Inter-American Observatory (CTIO)! Watch the sky's clear blue give into the sunset's warm hues as you sit in front of CTIO's telescopes, namely from left to right: the Curtis Schmidt Telescope, the Víctor M. Blanco 4-meter Telescope, the SMARTS 1.5-meter Telescope (partially hidden), and the SMARTS 0.9-meter Telescope. Sitting on the tall tower is the non-operational DIMM1 Seeing Monitor.
