Milky way

29.9.2022 at 23.15 - 00.15 - Rovaniemi (V)
Samuli Rosenberg

The Milky Way photographed north of Rovaniemi. Captured on a moonless night, with the dim northern lights glowing in the northern sky, on a frosty day of a few degrees below zero.

The pictures are towards the zenith so that I could get the Milky Way and Andromeda in the pictures (Figure 1) and classically west towards the central parts of the Milky Way. (Figure 2) I set the first picture so that I get Andromeda and the Milky Way in the picture. During the processing phase, a star nebula popped out of the im...

Samuli Rosenberg

Empa has never seen such a spectacular avalanche cloud. I was at home and the attention was drawn to the dark clouds approaching on the horizon, I left the plane to see if it was a thundering cloud that it was not yet then. A moment later I woke up to a thunderstorm and noticed that a avalanche cloud had formed in the sky, so I left quickly at the edge of the field along Vaalantie. So I started an electric orange Fiat Punton and drove through the village while admiring the approaching avalanche cloud. Eventually I arrived and parked the car at the bus stop and took the camera and set out to lo...

During the thunderstorm, it rained quite briskly and it was left in the yard so that the dog cage flooded. The first 3 pictures were taken during the rain when I tried what kind of pictures you get when "playing" with the shutter speed ps. I am not quite sure about the time of the clock because I do not really trust the camera clock

It was a bit like forgetting these pictures in the depths of that Computer Elikkä was at that cottage in Hailuoto and I thought to take a picture by the sea where I saw this handsome Cloth, which was presumably still accompanied by a Transatlantic Cargo ship about 10km away, according to local fishermen. I remember the island is about 10 -14km away

I woke up to a roar, ran, taking the wires off the walls, looked out, ran to get the camera, and then started pounding. Screenshots from the video, I ended up in the video because the lightning was pretty low so I could even capture something There seems to be a jet stream that doesn't show up here Even in that video where I suspect Kalevantule is https://www.facebook.com/photo.php?v=1435446003374831&set=vb.1416690798583685&type=2&theater
