Clearly visible night shining clouds

Antoine Chauveau, Ursa (Helsinki)

Good night cloud play. Among these were also red clouds moving in different directions.

ISS

22.3.2021 at 20.32 - 20.37 - Helsinki (IV)
Antoine Chauveau, Ursa (Helsinki)

The ISS rises under Orion, competes for glory with Sirius, and eventually disappears into the shadow of the earth. The main image is a stack of 45 shots with star motion compensated. The second is a different interpretation of the same material with asterisks. Timelapse video also available: https://vimeo.com/528033545

Telescopic comet NEOWISE

9.8.2020 at 00.05 - Helsinki (II)
Antoine Chauveau, Ursa (Helsinki)

A single square of Neowise, it was already too close to the horizon to make stacking a joy. The intention was to get C / 2017 T2 (PANSTARRS) in the same image, but nothing stuck to the cell. The location of Panstars is here crawled out of the picture.

Binocular comet NEOWISE

18.7.2020 at 01.15 - Helsinki (III)
Antoine Chauveau, Ursa (Helsinki)

Neowise is approaching the stars of Talitha and Talitha Australis. This helps to estimate the length of the tail, which remains less than 1 degree when dimmed by night clouds.

Great night cloud play.

Binocular comet NEOWISE

10.7.2020 at 00.30 - 02.00 - Helsinki (III)
Antoine Chauveau, Ursa (Helsinki)

Today, the comet had already become an easy binocular target. It was best seen around 0:30 to 1:30, after which the night clouds disturbed. I couldn’t see anything with the naked eye, even though I knew exactly where to look. A stack of about 35 images makes a moderately visible tail.

Binocular comet NEOWISE

7.7.2020 at 01.05 - 01.20 - Helsinki (III)
Antoine Chauveau, Ursa (Helsinki)

Certainly already a great comet further south, here mostly challenging, especially on a cloudy and windy night. The comet's head and even a small tail were visible with binoculars as the clouds appropriately receded during the darkest part of the night. The second picture shows how low and light the comet is in the sky. It’s roughly in the middle of the picture, a little above, and trying to hide behind a thin cloud. Closer to the top right is the star Theta Aurigae, who helped with the positioning. In the third picture, 14 samples were stacked and the tail was brought out a little better.

Venuksen peitto

19.6.2020 at 11.09 - 11.20 - Helsinki (III)
Antoine Chauveau, Ursa (Helsinki)

I had never searched for Venus so close to the Sun before, however, it was found in a few seconds through the camera. Here are a couple of pictures before the overlay, and an overlay video. The demarcation of the latter did not succeed very well, but fortunately the disappearance of Venus was completely recorded.

Dim night shining clouds

23.5.2020 at 00.40 - Helsinki (II)
Antoine Chauveau, Ursa (Helsinki)

The first night cloud observation of the year, quickly photographed through the windows of the apartment.

Venus ja Seulaset (M45)

3.4.2020 at 23.20 - Helsinki (IV)
Antoine Chauveau, Ursa (Helsinki)

The clouds receded appropriately as the evening progressed, and it was nice to watch this encounter right from the balcony.

Starlink

9.3.2020 at 06.04 - 06.24 - Funchal, Madeira (III)
Antoine Chauveau, Ursa (Helsinki)

Penumbral lunar eclipse

10.1.2020 at 21.30 - Helsinki (II)
Antoine Chauveau, Ursa (Helsinki)

Parachute agreements. The stage shouldn't even be described if there was a better offer ...

Venus ja Jupiter

21.1.2019 at 07.57 - Helsinki (III)
Antoine Chauveau, Ursa (Helsinki)

Looking away from the lunar eclipse, Venus and Jupiter gave their own presentation.

Total lunar eclipse

21.1.2019 at 06.32 - 07.55 - Helsinki (IV)
Antoine Chauveau, Ursa (Helsinki)

This was long awaited! In 2015, in the same place and even earlier in the morning, only a partial phase and clouds were visible. In the winter of 2018 nothing was visible, and in the summer of 2018 only glimpses through the clouds.

Bright night shining clouds

Antoine Chauveau, Ursa (Helsinki)

The day's night clouds quickly captured through the apartment's window.

Total lunar eclipse

27.7.2018 at 23.55 - 00.25 - Helsinki (IV)
Antoine Chauveau, Ursa (Helsinki)

The perfect phase meant to be divided behind the clouds once again, but the moon still chopped through the cracks of the clouds, perhaps a total of five minutes of eclipse in the last 20 minutes. After that, the clouds receded for a moment, and the partial phase was well visible.

Bright night clouds in the north.

ISS:n Auringon ylikulku

21.10.2017 at 14.14 - Helsinki (III)
Antoine Chauveau, Ursa (Helsinki)

Calsky announced the opportunity to see the ISS pass in front of the sun in Helsinki. Since the weather wasn’t quite cloudy, I didn’t frost the telescope out, I just took the superzoom camera. At first, it seemed like a good decision as a big cloud threatened to cover the aurigo as the H-moment approached. However, it was lucky, during the second it took, a flock of migratory birds also flew in front of the sun, and only a minute later the sun disappeared behind the cloud. So this became a funny picture, but the equipment in use did not allow for the desired quality.
