Orion and the northern winter constellations and Milky Way setting at dawn over the Chiricahua Mountains of southwest Arizona, near Portal, AZ. The waning crescent Moon in the west provided the illumination in this dawn shot from December 6, 2015. Orion is just above the main peak at centre, with Sirius, in Canis Major, to the left and Aldebaran, in Taurus, to the right. The Pleiades are setting at right. The star cluster at top is the Beehive, M44, in Cancer. Bands of airglow add the red streaks. The site is the Quailway Cottage near Portal, Arizona. This is a stack of 4 x 2 minute exposures, tracked, at f/3.5 with the 15mm full-frame fish-eye lens and Canon 6D at ISO 1250, for the sky, and the same specs for 4 exposures, untracked for the ground. Each set was mean-combined stacked to reduce noise.
The arch of the Milky Way in the northern autumn and early winter sky, from Arizona on December 5, 2015. The Milky Way extends from Aquila to the left, in the southwest to Cassiopeia at top right, to Perseus and Auriga at far right, in the northeast. I shot this from the Quailway Cottage near Portal, Arizona, latitude +32° N. The view is looking north toward the celestial pole. Polaris is just right of lower centre. This is a stack of 8 tracked exposures, each 3 minutes at f/2.8 with the 15mm lens and Canon 6D at ISO 1600, with the ground coming from one exposure to minimize blurring. The camera was on the iOptron Sky-Tracker.
The Zodiacal Light in the the late autumn evening sky from Arizona, overlooking the Chiricahua Mountains near Portal, AZ. The Zodiacal Light exends up from the horizon to the angled following the ecliptic. The summer Milky Way setting into the southwest extends up from the horizon to the right, running through the middle of the Summer Triangle stars. A satellite streaks across the Zodiacal Light, in a flaring path. I shot this from the field at Quailway Cottage. This is a stack of 7 x 2-minute exposures at f/2.8 with the 15mm full-frame fish-eye lens and Canon 6D at ISO 1250. All exposures were tracked on the iOptron Sky-Tracker. The ground came from one exposure to minimize blurring.
