Stock Photo - Circumpolar star trails over the upper field of the Texas Star Party, May 13, 2015 ...
. The star party attracts hundreds of avid stargazers to the Prude Ranch near Fort Davis, Texas each year to enjoy the dark skies. The three observing fields are filled with telescopes from the basic to sophisticated rigs for astrophotography. I aimed the camera to look north over the field to capture the stars circling around Polaris in circumpolar trails over about 1 hour. Some cloud and haze obscured parts of the sky. Lights from cities to the north add the sky glow at right. The streaks at top are from the stars of the Big Dipper. . . This is a stack of 55 exposures, each 1 minute long, at f/2. 8 with the 14mm lens and Canon 5D MkII at ISO 3200. The foreground comes from a single image in the series, masked and layered in Photoshop. The images were stacked using the Long Trails tapering effect with the Advanced Stacker Actions from Star Circle Academy.
