Primary reflection rainbow

16.9.2022 at 18.38 - 18.57 - Janakkala (V)
Petri Kuossari, Riihimäen tähtit. yhdistys

Although it was an interesting looking rainbow, to the naked eye it looked as if there were three or four side rainbows and also strange reflections in the horizontal plane, maybe someone with expertise can elaborate. As the journey continued, eventually the whole rainbow came into view. I adjusted the color tones for the last picture.

I don't know if it makes sense to photograph objects in the deep sky with a full moon, but I still photographed the Ghost of Cassiopeia in the picture.

On the first night of the Ursa deep sky meeting, the third target was Barnard 142 and 143. This was selected in such a way that someone threw me the coordinates from the dark and Vesperan headed for the target.

I photographed this Trifidisumu during the Deep Sky meeting of URSA at Tähtikallio in Artjärvi on Friday as the first target. The surprise was that I was able to capture this height when it was -11- -15 degrees at the site. Thanks for the good observation point of Tähtikallio.

NGC 281

Petri Kuossari, Riihimäen tähtit. yhdistys

The weather report unexpectedly changed towards the evening in a favorable direction. Nothing else, when Vespera went out to cool off, I did think twice when I looked at the gloomy clouds in the sky, but yes, the sky opened. The first target I took was the Pacma nebula, which was also the last of the evening as Vespera closed itself when it recognized the arrival of the cloud rafts at midnight.

On Finland's Nature Day, people were encouraged to sleep outside, well, I couldn't wait to sleep, but I photographed nature's own play. While both telescopes were working, I took pictures of the atmosphere with my cell phone. The first picture captured Seulaset, Mars, the reddish aurora borealis and the fog rising from the field. In the second picture, Vespera and a foggy field. The third picture Alasjärvi, the Milky Way and shooting stars.

On Finland's Nature Day, I photographed eagle fog on Vespera. The misty field and the starry sky created a wonderful atmosphere. The colors of the first and second image have been slightly adjusted, the third image is unprocessed. I also added a minute-long video of the formation of the image on the tablet screen. Pretty quickly the M16 forms appear.

On Friday morning, I was leaving for a trip and packed my equipment for an early morning wake-up call, but the clear sky took the win and the tubes out and to shoot. Here is one of the many objects from the night Iris fog. The morning wake-up was successful according to the schedule. The first raw image, the tones of the second image adjusted

Petri Kuossari, Riihimäen tähtit. yhdistys

I observed the asteroid 2100 Ra-Shalom with another tube and wondered what would be a suitable target for Vespera. The crescent of the moon 33% rose into the sky from behind the cloud gauze. I decided to try the straight up Joutsenen Pelikaanisu, where the sky was clear and the Milky Way was visible with the naked eye.
