At Cerro Tololo, Chile. From left to right: the Schmidt, 4-meter, 1.5-meter and 0.9-meter domes taken in a long exposure. Stars trail around the Celestial South Pole. The moon illuminates the domes from the left (East). The exposure was stopped just after moon rise. The soft, wide trail just to the right of the 4-meter dome is from the Large Magellanic Cloud.
