The stars, Milky Way, and constellations of the northern winter sky, including the Winter Hexagon of bright stars, and the Winter Triangle of Betelgeuse, Sirius and Procyon, in a wide-angle shot from the snowy horizon to Capella nearly at the zenith. Orion is at centre. His Belt point up to Taurus and down to Canis Major and Sirius. The Beehive Cluster is at lower left, while the Pleiades is at upper right. There are deer tracks in the snow. With the 14mm Sigma Art lens at f/2 for 20 seconds at ISO 3200, with the ground a stack of 4 exposures to smooth noise. All untracked. Shot from home January 13, 2018, on a mild winter night at -8° C or so. Diffraction spikes added with Astronomy Tools actions.
Depictions of two kinds of dust in space: At left the pyramid-shaped glow of Zodiacal Light caused by sunlight reflecting off interplanetary dust in the inner solar system from comets and meteoroids, while at right is the band of the bright Milky Way, made of stars in our galaxy. But along it lie dark lanes of interstellar dust made of carbon compounds made in the atmospheres of stars and dispersed into the Galaxy. This is from the Quailway Cottage near Portal, Arizona, on December 14, 2017, looking west to the Chiricahua Mountains of southeast Arizona. The Summer Triangle stars are setting into the west with Deneb at top, while Vega is at right. Altair is lowest at centre. The sky is a single 30-second exposure, while the ground is a mean combined stack of 8 30-second exposures to smooth noise, all at f/2.5 with the 14mm lens and Canon 6D MkII at ISO 6400. Not tracked — these were part of a 350-frame time-lapse.
A selfie at Reesor Lake in Cypress Hills with the Milky Way, July 29, 2017, with the Canon 6D at ISO 6400 and 14mm Rokinon SP at f/2.5. The camera is shooting a panning time-lapse with the SYRP Genie Mini. Dark frame included for demo purposes. The dark frame was taken immediately afterwards but is a single dark.
