Devils Garden Milky Way
Milky Way and airglow near Devils Garden campground.
Airglow is caused by various processes in the upper atmosphere, such as the recombination of atoms, which were photoionized by the sun during the day, luminescence caused by cosmic rays striking the upper atmosphere and chemiluminescence caused mainly by oxygen and nitrogen reacting with hydroxyl ions at heights of a few hundred kilometres. It is not noticeable during the daytime because of the scattered light from the sun.
Camera: EOS 7D Mark 2
Lens: Samyang 10mm f/2.8 ED AS NCS CS @ f/4
Sky: 25s @ ISO 6400
As the foreground was very dark and flat, it was combined with a second exposure from the same position that was taken a bit earlier with more light and some lightpainting.
