Orion and the winter sky with Venus, setting into the western twilight, over Turret Arch in Arches National Park, Utah, on April 6, 2015. Venus is the bright object at right under the Pleaides. Sirius is the bright star at left, with Procyon the bright star ar top left.
This is a stack of 7 x 30-second exposures for the ground to reduce noise, and a single 30-second exposure for the sky to keep the stars untrailed, all at ISO 3200 with the Canon 6D and Rokinon 14mm lens at f/2.8. Taken in late twilight.
