Venus and Jupiter

1.3.2023 at 18.00 - 19.00 - Kajaani (IV)
Mauri Hyvönen, Kajaanin planeetta

When the evening got dark, I pointed the camera in the direction of the sunset and took pictures of the meeting of Venus and Jupiter. Fortunately, the weather was cloudless at that moment. A few thin clouds drifted towards the planet duo, but luckily I was able to capture the event. In the second picture, Jupiter's largest moons can just be seen if you squint very carefully.

All-sky aurora

26.2.2023 at 23.10 - 00.15 - Kajaani (IV)
Mauri Hyvönen, Kajaanin planeetta

On February 26, 2023, an aurora borealis was observed in Teppana, Kajaani. Although there was light pollution, the northern lights were very visible. Rarely in the heart of the city do you get to see a decent Northern Lights show. The play continued until the 27th of February.

Partial solar eclipse

25.10.2022 at 12.10 - 14.30 - Sotkamo, Naapurinvaara (III)
Mauri Hyvönen, Kajaanin planeetta

The morning seemed to dawn sunny in Kainuu. As noon approached, fog began to gather in the sky. When starting the observation at Naapurinvaara, it seemed at first that the sky would remain cloudless. About 20 min. from the beginning of the eclipse, the fog also started to rise to danger. The fog remained sufficiently thick throughout the eclipse that I was able to take pictures without a solar film. I also tried to shoot with a phone, a Samsung S10, and one photo was taken with the camera on a tripod and the eclipse visible in the sky. That actual picture of the eclipse is timed close to the m...

Binocular comet Leonard

7.12.2021 at 02.40 - 04.00 - Kuhmo, Lentiira (I)
Mauri Hyvönen, Kajaanin planeetta

The weather became clearer after midnight on December 7, after a long period of cloudiness from -25C. I used Astrotrac for follow-up. Exposure 60 sec. single exposure. Optics Samyang 2.0 / 135mm. Camera Olympus OM-D E-M5 mk2.

Quiet aurora arc

12.8.2018 at 00.45 - 01.00 - Kajaani (II)
Mauri Hyvönen, Kajaanin planeetta

I noticed that others had also immortalized, at least for themselves, a rare event. Illuminated by night clouds and northern lights at the same time. Be it a memorable experience.

Partial solar eclipse

Mauri Hyvönen, Kajaanin planeetta

The weather favored tracking the eclipse, only a gust of wind posed a challenge.

M42

16.12.2015 at 23.28 - Paltamo (IV)
Mauri Hyvönen, Kajaanin planeetta

December 16-15 was a long time opportunity to test the accuracy of the astrotrac. I drove in the fair -23C frost (the frost at the scene was that -23) on the Paltamo side behind Kontiomäki on a gravel mound where a great starry sky opened up. There was no "harm" in the northern lights and moon when photographing the sky. I think the tripod was set up well, I was able to shoot effortlessly in 4-5 min. exposures without streaks left by the stars. The image is slightly adjusted for brightness and contrast.

Active aurora band

7.10.2015 at 20.45 - 22.00 - Kajaani (III)
Mauri Hyvönen, Kajaanin planeetta

I slipped out before 9pm and noticed that now I don't seem to need to go very far to see the northern lights. The northern lights were so bright that I decided to go downtown to shoot. However, the bright street lights reflect so much into the camera optics that I went to the riverbank to shoot. One photo is taken from the Citymarket parking lot and the rest from the riverbank.

Total lunar eclipse

28.9.2015 at 05.55 - 06.30 - Kajaani (IV)
Mauri Hyvönen, Kajaanin planeetta

I started an observation tour of Vuokatti from the top of the danger. There I noticed that there seems to be a cloud edge in the direction of Kajaani. Rigging in the car and bow towards Kajaani. In Kajaani I got the first picture taken in the pennant valley. The picture shows the extra brilliance of the street lights on both sides of the moon. Other pictures are from the top of Vimpelinvaara.

There was a heavy fog in Kajaani in the morning. Fortunately, a place was found in Vuokatti where the event was well visible.
