I photographed this dark fog at the Deep Sky meeting of URSA on Tähtikallio in Artjärvi on the night of SA-SU. On the weekend in question, there was a 30-year anniversary meeting and there was a really nice crowd and the Halo Deck was almost full of telescopes. Great meeting! Exposure for 3 hours and 10 minutes.

Mainiosti olet onnistunut tämän vangitsemaan! Pimeät sumut ovat vaikuttavia näin, kun hahmo erottuu taustataivasta vasten
