The company draws Fracastorius in late night lighting. It was formed on a 400 km diameter ring of the Nectaris basin, and tilted towards the sea due to the depression of lava. In a better picture and better lighting, an east-west slope stands out in the middle of the crater. On the north side of the channel, the lava is darker, and less cratered than in the south. The Fracastorius, more than 120 km in diameter, is No. 21 on the Lunar100 catalog.

The constellation NGC 6823 is surrounded by nebula NGC 6820. In the picture, an open star cluster in the direction indicated by the most spectacular gas pillar of the nebula was formed by about 2 million. years ago, and it forms new stars from the surrounding material. - (Source: Nasa - https://apod.nasa.gov/apod/ap141008.html

This is a rather exotic Messier site considering Finnish conditions, as this fog is visible at very low latitudes in Finland. In this image, the object is at a maximum height of about 2.5 degrees above the horizon.

Quite a northern lights show was recorded at the Bear Camera last night. It was a bit of luck insofar as the camera had been off for a whole week due to a software update, but I got the job done spinning at just the right time. After all, I couldn't properly prepare for this, even the clouds were promised ... the shooting settings were still in search. #sarg

Milky way

Matti Tainio, Porin Karhunvartijat

Even though I was in the Rovaniemi Urban Area, it was dark enough for the Milky Way on the banks of the Kemijoki River. Something stood out even to the naked eye and already 20 seconds of exposure brought out the mists.

Vesa Puistovaara, Porin Karhunvartijat

Now I had a great opportunity to try shooting nebula for the first time, so it didn't help - I had to try it! The beginning went quite well, taking hydrogen pictures, but as the subject slowly climbed towards the zenith, stock problems began to hit my nerve cells. - color images were not taken ... On the other hand, I only caught hydrogen pictures, and I also got them commendably ... once again I have to be quite happy with this output too :) -maybe later the colors will be found in this sample (?) -

The first night of the 2021 Deep Sky meeting was just over three hours clear of the early night. During this time I filmed a time lapse video of the Milky Way, the video can be found on my Youtube channel: https://youtu.be/99aeQ4N11Zc I will also observe one single box from the time lapse series. The photos were taken between 9.30pm and 2.30pm. The meeting was arranged in the usual way at the Ursa Tähtikallio Observatory. I also wrote a short story on my blog about the meeting.

We were admiring and photographing the Milky Way in Pyhäranta, Rohdais, when in the middle of everything we saw behind us our backs a strange, dazzling silver-bluish light phenomenon in the northeast, which brightened in our eyes. The phenomenon was absolutely insanely bright and very strange looking. At this point I cursed the long exposure of the Milky Way and the 30s have never felt as long as now ... The phenomenon ran low on a really hard ride from us to the northeast to the northwest and eventually disappeared beyond the light sea and forest border of Rauma. The first thought was when I ...
