LDN673 - 3.9.2022 at 22.16 - 4.9.2022 at 02.24 Orimattila, Artjärvi, Tähtikallio Observation number 109381

Visibility V / V

Tero Hiekkalinna, Ursa (Helsinki)

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
