Foto de stock - Star trails showing Orion and Taurus rising behind the rock formations of City of Rocks State Park, New Mexico. I shot this Monday, Dec 29, 2014. The colours of the stars and trails have been boosted in vibrancy to show the colour differences better. Red Betelgeuse is at left, while the pinkish Orion Nebula is at centre. The cyan trail at right is Comet Lovejoy (C/2014 Q2). Light from the waxing quarter Moon illuminates the foreground. A satellite streak is at right of centre. . . This is a stack of 260 exposures, each 30 seconds at f/2/8 with the 24mm lens and Canon 6D at ISO 400. The foreground is mostly from one frame, the first frame, to preserve shadows. I also added larger star glows around the brighter stars of Orion to make the constellation patern more obvious. It starts just above the rocks at lower left and rises to above centre. The images were stacked with the Advanced Stacker Actions from Star Circle Academy, using the Elastic Stars effect to add point-like stars from the first and last frames.
