Zodiacal light

20.2.2020 at 18.50 - 22.50 - Joensuu (II)
Antti Taskinen, Ursa (Itä-Suomi)

Zodiac light spotted. There was nothing particularly bright from my observation site where there was a fair amount of wasted light, but it was still visible visually. Venus was so bright that it almost dazzled just in the direction of the zodiac light. Also included is a timelapse animation of the phenomenon and its fading from 18:50 to 22:50.

Quiet aurora arc

18.2.2020 at 21.00 - 22.00 - Joensuu (II)
Antti Taskinen, Ursa (Itä-Suomi)

Let's make one northern lights observation from eastern Finland as well. I happened to see Zeniit’s Facebook update in the evening, where any northern lights were posted. Enthusiastic about this, I next looked at the updated activity situation on the Finnish Meteorological Institute's Northern Lights and Space Weather page. Yeah-o, it looked promising. Then a glance out the back door and a little disappointment - there is nothing in the sky resembling any northern lights. Later in the evening, I started to tune the tracking stand in the yard when the sky looked quite clear and outright...

Mare Imbrium

4.2.2020 at 20.20 - 22.40 - Joensuu (III)
Antti Taskinen, Ursa (Itä-Suomi)

The cloudless sky, calm weather and the "handle" of the moon roaring in the sky attracted us to pile up a telescope in the yard. When seeing also turned out to be quite moderate, it was nice to spend the evening watching and photographing the surface of the Moon. Figure 1 starring Sinus Iridum and numerous ridges (Dorsum Heim, Dorsum Zirkel, etc. unnamed). Figure 2 shows the plateau, craters and marginal mountains of Mare Imbrium. Rima Hadley also stands near the right edge of the picture, near which Apollo 15 landed in 1971. Picture 3 includes the craters of Plato, Cassini and Aristotle, as w...

Clavius

4.2.2020 at 18.30 - 22.40 - Joensuu (IV)
Antti Taskinen, Ursa (Itä-Suomi)

The cloudless sky, calm weather and the "handle" of the moon roaring in the sky attracted us to pile up a telescope in the yard. When seeing also turned out to be quite moderate, it was nice to spend the evening watching and photographing the surface of the Moon. I photographed the area of the Clavius Crater in the southern hemisphere on many occasions because the seeing seemed to improve as the evening progressed and I always thought I would get a better result the last time. The attached picture was taken at about 10.20 pm. In the picture, in addition to Clavius, Tycho and quite a few other ...

Moon

10.1.2020 at 23.30 - 23.59 - Joensuu (IV)
Antti Taskinen, Ursa (Itä-Suomi)

After the half-shadow eclipse, it was a good opportunity to capture the full moon at a more accurate resolution because the atmosphere was quite calm. Too often these (turn) opportunities have not come to me. Looking at the mosaic I compiled, I was delighted to see that it shows the edge ramparts of the Orientale Basin, that is, both Montes Cordillera and Montes Rook, right on the west side of the visible side of the Moon. Or at least that’s what I came to after looking at the monthly maps. Apparently, lighting and libration were now appropriate for the appearance of these surface shapes. Mare...

Penumbral lunar eclipse

10.1.2020 at 19.00 - 23.15 - Joensuu
Antti Taskinen, Ursa (Itä-Suomi)

It was great to watch the lunar eclipse of the moon in great weather. It was a few degrees of frost and the sky was quite clear. I took pictures of the progress of the eclipse through the telescope every 3 minutes. At the same time, I watched the Moon with bare eyes and giant binoculars. The dimming of the moon was most evident on the camera screen and in the histogram of the images. With binoculars, the fading of the moon was also noticed quite clearly. During the deepest phase of the eclipse, the southern edge of the Moon also seemed darkened to the naked eye. The GIF animation is composed o...

Kvadrantidit

4.1.2020 at 03.00 - 06.00 - Kontiolahti (III)
Antti Taskinen, Ursa (Itä-Suomi)

I had never seen a decent swarm of stars before. For example, the maximum of Geminids last December was completely behind the cloud cover. Now, at the peak of the Quadrant, the weather forecast promised better and the phase of the Moon was appropriate, so I had to try it again, even though it meant falling through the night. I tuned the imaging equipment to the observation site while the clouds were still drifting in the sky. Fortunately, the sky gradually became clearer, though not quite bright enough, but enough that the quadrants began to separate. I had taken a folding chair with me, sitti...

NGC 1499

31.12.2019 at 21.53 - 22.33 - Joensuu (III)
Antti Taskinen, Ursa (Itä-Suomi)

The clear sky lured me out under the starry sky. My plan was to first photograph the California Nebula (NGC 1499) region for a couple of hours with camera optics and then a little more. However, the clouds came in the middle of it all to cheer up their presence, so we had to settle for less this time. Well, something grabbed the cell in just over half an hour. There seems to be quite a lot of dust around the fog. 1. the image is more cropped, repeat less.

Moon

31.12.2019 at 20.30 - 21.00 - Joensuu (III)
Antti Taskinen, Ursa (Itä-Suomi)

I watched the descending Moon and the lunar bridge it created on the ice of the lake. The sky was more or less cloudless, so the orbiter's descent below the horizon could be followed to the end. It was somehow a special atmosphere when at the same time the fireworks burst and the cargo ship approaching Joensuu rumbled on the back of the lake in the middle of the ice. In the last picture, the ship's floodlight already reached a little to illuminate the ice surface.

Moon

10.12.2019 at 22.00 - 23.00 - Joensuu (III)
Antti Taskinen, Ursa (Itä-Suomi)

There was no information about the halons of the Moon on the shores of Pyhäselä in Joensuu, but the wanderer was visible in the clear sky until a unified Cloud Cover arrived. The phase of the moon was now quite suitable for observing the surface forms just on its western edge. In memory, I made a mosaic picture of the entire Moon and also took a close-up of the Reiner Gamma and Struve Crater area.

Pearl clouds

3.12.2019 at 15.00 - Joensuu
Antti Taskinen, Ursa (Itä-Suomi)

I went to watch the sunset by the lake. The sky was cloudy by the way, but to the west was a strip of clearer sky. Some time after the sun had set, my attention turned to the more peculiar-looking blond, rather bright clouds that were directly to the west. At times, they came out better behind the edge of a dark, uniform cloud cover, and then went into hiding again. I would assume that these are now the pearl clouds, many of which have left observations in the Star of Heaven in recent days. In that case, this would be my first conscious observation of pearl clouds.

M42

5.11.2019 at 02.00 - 04.00 - Kontiolahti
Antti Taskinen, Ursa (Itä-Suomi)

The weather forecast promised clear skies, so I prepared to spend the whole night under the stars. When I arrived at the observation site, I assembled the telescope ready to shoot and waited for Orion's constellation to rise above the horizon. I had planned to photograph a couple of the objects in it. The intensifying frost made the nearby wetland and bird tower bang so that I was startled in between. After two in the morning, I headed for the tube towards Orion’s large gas mist M42 and collected for a couple of hours the exposures of different lengths for the HDR image, which is attached.

IC 434, Barnard 33, NGC 2023, NGC 2024

5.11.2019 at 00.50 - 02.40 - Kontiolahti (III)
Antti Taskinen, Ursa (Itä-Suomi)

Last night, for a long time, I got to aim at the sky with a telescope as the clouds tempered to stay away. As a target, I chose an area of Horsehead Nebula that I hadn’t previously tried to describe with my telescope. The "fog" above the horizon and light pollution hampered the shooting of the low-lying subject a bit, and the exposure time should have been longer. However, the character of the horsehead stands out, which was my original goal. While assembling the equipment, I noticed several starbursts, the finest being a bright and green fireball. Edit: image updated to better quality.

Pääsateenkaari

6.9.2019 at 18.15 - 19.25 - Outokumpu ja Joensuu (IV)
Antti Taskinen, Ursa (Itä-Suomi)

A little more spectacular rainbow for a long time. I made the first observation in Outokumpu and more on the Joensuu side. The interference arc was also visible at its best, but it did not seem to succeed in obtaining its image.

Moon

27.8.2019 at 02.01 - Joensuu (IV)
Antti Taskinen, Ursa (Itä-Suomi)

As I drove home from the shooting trip, the Crescent Moon shone beautifully in the low sky in the constellation of Gemini. I had to stop right to take pictures of when the country cottage stood out nicely. Clouds flew in front of the moon, and afterwards I noticed that there were a few hook-like shapes in the pair of pictures. Hardly any Kelvin-Helmholtz clouds, though? The brightest star on the right side of the moon is Mekbuda.

Clearly visible night shining clouds

18.8.2019 at 23.25 - 00.03 - Joensuu (III)
Antti Taskinen, Ursa (Itä-Suomi)

The appearance of illuminating night clouds in the sky was a pleasant surprise. At half past twelve, they stood out perhaps best from my own observation site (backyard).

Clearly visible night shining clouds

23.7.2019 at 00.30 - 01.05 - Joensuu (III)
Antti Taskinen, Ursa (Itä-Suomi)

I was already going to bed when I decided to check the situation in the sky once more. To my delight, I noticed illuminating night clouds appearing toward the north. In the same direction, there was also a brighter star, the Driver's Capella. I rushed into a nightgown on the yard with a camera and watched the screen for half an hour. There was no more affordability this time because of the early morning awakening. Anyway, a nice start to the night cloud season for me here in the latitudes of Joensuu.

Partial lunar eclipse

16.7.2019 at 23.00 - 02.00 - Turku (III)
Antti Taskinen, Ursa (Itä-Suomi)

The rocks next to Turku's Ispoinen beach opened up unobstructed views to watch the lunar eclipse. A small cloud of drift drifted in front of the Moon for most of the event, but it didn't bother me much.

Milky way

6.7.2019 at 23.00 - 00.00 - Sölden, Itävalta (IV)
Antti Taskinen, Ursa (Itä-Suomi)

During the summer vacation, it was possible to photograph the starry sky from latitudes a little further south. Although my observation site was close to the center of the village of Sölden, the Milky Way stood out clearly after dark. Jupiter also shone bright in the sky, in the picture it is above the mountain peak. It would be nice if you could see the center of the Milky Way from Finland too!
