La Palma 2019
During a technical mission at La Palma, I could make some nice pictures. I used the Sigma 10mm f/2.8 lens for the first time and I'm very impressed with the pictures. The zodiacal light is very easy to see. A group of amateur astronomers from Belgium and the Netherlands came to the Mercator telescope to do some observing with their own telescopes. The weather looked very promising at the beginning of the night, but sadly once it was really dark, the humidity rose to 100% and we could not observe...
