Morning Star, the Milky Way, and the Zodiacal Light
By: Alan Dyer
|Camera:||Canon EOS 6D|
Venus, now at its brightest as a morning star, shines amid the subtle glow of the Zodiacal Light.
This was the scene this morning, September 17, on a very frosty dawn at 5 a.m. from my backyard in southern Alberta.
Here, Venus shines nearly as bright as it can be, at magnitude -4.7, in the dawn sky as a brilliant “morning star.”
Venus appears amid the faint glow of the Zodiacal Light, sometimes called the “False Dawn,” stretching diagonally from the dawn horizon in the east, up and to the right, and reaching the Milky Way that runs vertically down the frame from top centre to bottom right.
Orion and the winter stars shine in the Milky Way, with Sirius above the trees at lower right.
The Beehive Cluster, M44, appears as the small group of stars above Venus. The Pleiades, M45, is at top right.
Mars is the brightest object left of Venus, with the bright star Regulus just below it and rising in the east. The stars of the Big Dipper are at far left at the edge of the frame.
The sky is beginning to brighten with the real glow of morning. It was a marvellous dawn sky delight.
This is a stack of 4 x 2-minute exposures, tracked and mean-combine stacked, for the sky and 2 x 2-minute exposures, untracked and stacked, for the ground to minimize blurring in the starlit ground. The Canon 6D was on the iOptron Sky-Tracker, shooting at ISO 1250 with the 15mm full-frame fish-eye lens at f/3.5. The stacking with a mean combine stack mode smooths noise in both sky and ground.
