Yesterday on the fire safety and science conference in the Netherlands we got a presentation of the work of the Ukranian fire fighters during war time, including a very impressive video. True hero’s! I hope for all of you we can end this war with the help of Europe.

Living in a very light polluted city it is a challenge to capture the dark nebulas surrounding NGC7023, the Iris nebula. After 13 hours this is the result.

Today we remember the Dutch victims of WWII and all conflicts after. Also the 25 soldier who died after the USA called for NATO article 5. Stop fascist regimes before history repeats!

Nice. More data is less noise. So add a few nights 😉 I did 12 hours on it.
