A Stunning Sky of Subtle Glows
What a fabulous night! The desert sky was full of subtle glows and myriad stars.
Friday, January 16 was a stunning evening for stargazing. I took the opportunity to shoot a 360° panorama of the evening sky, recording a host of subtle glows.
The Zodiacal Light reaches up from the western horizon and the last vestiges of evening twilight. This is the glow of sunlight reflecting off cometary dust particles in the inner solar system. From the clear desert skies it is brilliant.
The dark of the Moon periods in January, February and March are the best times of the year to see the evening Zodiacal Light from the northern hemisphere.
The Milky Way arches across the eastern sky from Cygnus to Canis Major. That’s light from billions of stars in our Galaxy.
At centre, in the circular fish-eye image above, is the small wisp of green Comet Lovejoy, near the zenith overhead and appearing at the apex of the Zodiacal Light’s tapering pyramid of light.
This view is from the same images used to create the circular all-sky scene at top, but projected in a rectangular 360° format.
I shot 8 segments for the panorama, each a 1-minute exposure at f/2.8 with a 15mm lens oriented in portrait mode, and using a Canon 6D at ISO 3200. There was no tracking – the camera was just on a tripod. Each segment is 45° apart.
I used PTGui software to stitch the segments into one seamless scene.
