Dusk to Dawn time-lapse at CTIO

While observing for the DECam Legacy Survey (DECaLS), Rongpu Zhou (University of Pittsburgh) set up a camera to capture a time-lapse of the evening. For the first 18 seconds of the video, the moon illuminates the foreground as if it were daylight, while the night sky rotates overhead. As the moon sets, many more stars become visible, and our galaxy, the Milky Way, rises as the Magellanic Clouds set behind the Blanco 4m Telescope. The time-lapse was taken on 4 March 2017.
