Visibility IV / V
A few rings of the Moon from last night. Actually, I was going to shoot the nebula with the drone, but the spectacular rings of the Moon took the win. The conditions were absolutely great. Completely calm, the temperature dropping to freezing and a lot of fog in low places. The atmospheric chatter of a barn owl could still be heard from the nearby forest on the shore of the lake. With a drone, I measured the thickness of the fog layer about 50 meters above Saimaa (picture 5).
