A clear night in the Alps is something truly special for any amateur astronomer. The sky was mostly clear, and the air was very transparent. I caught a fleeting glimpse of the setting moon, first only seeing the earth-illuminated dark side peeking out behind a mountain ridge. But I only had wide-angle lenses with me, so I focused on the milky way.

In the images towards the east I noticed the distinctive colors and pattern of airglow https://en.wikipedia.org/wiki/Airglow :

The colored stripes in this image are caused by airglow, oxygen and nitrogen molecules in the air are partly ionized and give off a faint glow. (https://en.wikipedia.org/wiki/Airglow) Nikon Z6, AF-S Nikkor 20mm f/1.8G, 10s at f/2.2, ISO 3200

I also made a short animation of the airglow slowly moving in front of the stars:
