Airglow explosion in the northern sky
I created this image from a time-lapse. This is a method that I like to use! If you take a static time lapse you end up with a nice video, if you take 20 pictures from this series and stack them and edit them then you usually end up with a nice picture.
In this picture I was very focused on the airglow (the yellow/greenish glow on the horizon). Airglow in this form can be seen very often on La Palma because it is extremely dark there in all directions! In my experience, you see it most often over the sea to the north and east, but it can also come directly overhead and maybe I was just "unlucky" in the 3 weeks I was there...
