Gegenschein from Simplon Pass

The elusive gegenschein phenomenon captured on a clear, clear night from 2000 m. of the Simplon Pass in Switzerland. The antisolar point is located in the top right image, barely visible as a very faint and diffuse nebulosity extending over 20° in a sky with green and orange airglow. The image was highly contrasted to accentuate the phenomenon.

Canon 700D full-spectrum + lens 10 mm., star tracker Vixen Polarie.
