PICTURE OF THE DAYsee all »

Sky trails

In this Moon and star trail image, we can see the different colors from various types of stars. The photographer captured this scene in Miradouro de Santa Iria, Azores. The exposures start at nautical twilight and progress until the Moon sets behind the clouds. The picture shows the light pollution coming from Ribeira Grande, as well from Lagoa and Ponta Delgada. The strong small path near the Moon at the top of the image belongs to Jupiter. (Canon 60Da DSLR, 24mm lens at f/2.8, ISO 1000, three hundred and fourteen 15-second exposures, stacked, taken February 5, 2014, between 10:47 p.m. and 12:17 A.M. local time, from Miradouro de Santa Iria, Azores)
