Pico de la Cruz Milky Way Panorama

Details

In June 2022, I flew to La Palma again to take new pictures of the night sky. The special thing about this trip was that I wanted to try out a new imaging technique. The technique consists of capturing the H-alpha nebula areas (the red spots in the image) individually with a narrowband filter and then later incorporating them into the normal color image. As you can see, I succeeded!
