4 frames aligned and stacked in Sequator for enhanced light and reduced noise. Vibrance, saturation, and contrast were increased in Photoshop to bring out airglow details.

I was doing a sequence of shots to show the Milky Way rising over this solo. Some of the early frames had this lovely airglow. The orientation of the ripples of airglow lends a "crepuscular rays" effect over the solo.
