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.
Stars setting in trails over the Athabasca Glacier and Columbia Icefields, Sept 14, 2014. These images were taken after moonrise so the sky and landscape are bright. This is a stack of 100 exposures, composited with Advanced Stacker Plus actions in Photoshop, with Comet effects, with the ground coming from a subset stack of 8 images to reduce noise. Each exposure, taken as part of a time-lapse sequence, was 45 seconds at f/2.8 with the 16-35mm lens at 23mm and Canon 6D at ISO 4000.
