Fagradalsfjall Lava Fountain
Another single image from the new eruptions on 11 Sep 2021, the most prominent lava fountain in the middle of the lava field in Geldingadalir.
Fagradalsfjall Volcano Eruption
A trip to Iceland in September, with high hopes to see the Fagradalsfjall volcano in action. At first a bit disappointed, because activities stopped just before we arrived, we were lucky on the last but one day and the fourth hike into the volcano area. A splendid display of lava fountains and flows from the late afternoon into the night. More images/videos to come!

NGC 6888 – Crescent Nebula – Ha
Still a work in progress, mastering the QHY268M with the Optolong LRGBSHO filter set. Seems like a setup with reserved filters is required for the Esprit 100 ED with the original flattener, in order to avoid strange reflections from bright stars such as Deneb or Sadr. Shooting a familiar target here.

Auch schon wieder 15 (!) Jahre her, der beginnende Abriss des Barmer Viertels. Da hat es mich sehr gefreut, dass die Bilder jetzt zur Illustration in einer Ausgabe der moderne REGIONAL genutzt wurden: “Sorge um den Bestand”.
Allzu oft wird Bestehendes geopfert, um vermeintlich Besseres zu schaffen.

Partial (Annular) Solar Eclipse 10 Jun 2021
Lacking the joys of eclipse chasing, at least a partial solar eclipse at home (annular in North America).
