Riku Poskiparta, Porin Karhunvartijat

We went with the hostess once again for an evening ride, this time to Laitila Black Lake. We stepped onto the beach to see how the Milky Way would look right. Well, it was visible. My wife already had camera stacks with me by the beach, but I still have it in the car, so the tripod ... the camera is always in my pocket. quickly get a tripod from the car that just didn’t have time for the scenery to change, didn’t have time and grabbed the best picture I’ve ever taken on my cell phone.

Primary rainbow

12.10.2021 at 17.10 - 18.10 - Ulvila
Vesa Puistovaara, Porin Karhunvartijat

The cloudy sky in October cracked so much that even the rainbow appeared on the exhibits! I also tried to compile a short, about an hour-long, timelapse video about the birth and death of the arc itself ... badly the latter, but that's how it wants to go in this life - fleeting (even great moments); A few previous observations of the 'life cycle' of the rainbow are already here in the Sky Watch, but isn't this suitable as an extension of the motley arc set? The quality of the video is not dizzying, and the Cloud Cover coming from the north can even distract from the rainbow on ...

Okay, Okean-O satellite pictured. It may be necessary to clarify this observation a little. In early 2021, I set a desire & goal for myself to recover the ‘streak’ left by 100 different satellites in the Bear Camera. However, this is the so-called allsky camera, so it is almost impossible to capture any single phenomenon or event from the images in the camera. Instead, I realized that I could try to get to know the world of satellites myself - when they are enough, almost annoyingly ... but also because they are quite visible celestial bodies. The Bongaa 100 , organized in honor of Ursa's ...

Rocket-related clouds

Tuikku Asikainen, Porin Karhunvartijat

I was describing the northern lights at the base of the Keminmaa lookout tower. My spouse exclaimed from behind him, "Suddenly Twinkle, turn the camera west! See what a miracle there is!" For an unauthorized length of time, I was stupid before I got the camera in place, then I got three pictures of it. And I have to say that it was quite a wild feeling for such a sci-fi movie friend to find out calmly what could be the cause of the phenomenon. Damn great experience!

NGC 6960

30.8.2021 at 23.00 - 01.00 - Pori (I)
Jarkko Suominen, Porin Karhunvartijat

Sometimes it is easy to describe, although as a rule only the tested operation of the equipment after maintenance came. Here's a "service night" of gauze mist, which is a supernova remnant in the constellation of Swan. Exposure taken for 2h.

NGC 281

27.9.2021 at 00.00 - Nakkila (IV)
Tomi Kurri, Porin Karhunvartijat

NGC 281, or Pacman Nebula, located in the constellation of Cassiopeia, is an emission nebula and consists mainly of hydrogen. At a distance, the fog is about 9,200 light-years away from us. I photographed the subject on several autumn evenings and the data was collected in both RGB and narrowband. The total exposure time of the image is 5.5 hours.

IC 1396

3.10.2021 at 01.00 - Ulvila (III)
Vesa Puistovaara, Tomi Kurri, Porin Karhunvartijat

A piece of the most beautiful space ... small, but the most famous and described part of the object itself IC 1396. Forecasts for the weather seemed completely unworthy for most of the week, but as if by order for Saturday night, there was a fairly clear observation time! It must have been true to try to take advantage of. The evening went quite calmly, without thinking about major worries - the coffee was consumed almost in a pan and time passed surprisingly quickly. Observations were made at several sites, both at the observatory and remotely. In the "Picture of the Hour" last night's gi...

Supernova 2021rhu

Kari Laihia, Juha Blad, Tomi Taskinen, Toni Veikkolainen, Veikko Mäkelä, Porin Karhunvartijat

SN 2021 Rhu Pegasus in the supernova galaxy NGC7814 (little sombrero) was filmed on the first night of the August 2021 extra work. Toni and Veikko described Kari as a measurement sensor. The supernova was discovered by the Zwicky Transient Facility (ZTF) exploration program on Palomar’s Samuel Oschin 48-inch Schmidt telescope on July 1, 2021. The ZTF tracks all changes in the starry sky, supernovae, comets, asteroids, etc. Source ZTF https://www.ztf.caltech.ed The measurement was complicated by the halo in the center of the galaxy, which had to be dimmed considerably in order for the object to...

Vesa Puistovaara, Porin Karhunvartijat

My dilute but emotional gift to Ulvila Observatory from its 30-year journey. Apparently Pluto has not been observed from there before - let alone photographed ... but I had to try to get pictures of this ex-planet from there now as well. Quite streaks are the stars, and also the target itself - but recognizable nonetheless. One way or another: In this case, Stellarium served as a tool for identification, which also provides more extensive information about the situation at the time of filming ...

Montes Caucasus

28.9.2021 at 03.10 - 04.00 - Harjavalta (IV)
Jari Kuula, Porin Karhunvartijat

The company draws the Caucasus Mountains in its evening light. Calippus C has lost its western edge, but the eastern edge, especially its southern part, rises to a height of 5 km. Montes Caucasus is said to be an Imbrium throw, but the concentric alignments don't really fit !? A cell phone rap at 3:49 a.m. shows a low ridge heading northeast from Theaetus. This shallow form has a width of about 25 km and a length of about 100 km. The ridge did not appear in the drawing, but the shoreline is also in the shade.

SN 2021 wuf The supernova of Hercules in the galaxy pair NGC6500-NGC6501 was filmed on the second night of the September 2021 work. The supernova was discovered in the ATLAS NEO asteroid exploration program on August 23, 2021. The supernova is classified as type 1a. Discovery Report IAU AstroNote 2021-224 . Our shooting took place in challenging conditions with clouds interfering. Therefore, the report contains as many as 3 observations showing the variation of the weather. Figure 1 is a summary image of a total of 1-11 images. Figure 2 Sum...

Vesa Puistovaara, Porin Karhunvartijat

Flaming Star Nebula , Flaming Star Nebula, IC 405. The upper clouds largely messed up my plan, so I ended up taking a small glimpse of this rather "ugly" object in the Constellation of the Driver. The runaway star AE Aurigae (pictured in the middle) illuminates the fog.

The comet C / 2017 K2 (PANSTARRS) was filmed on the second night of the September 2021 campaign. A comet on a hyperbolic orbit was discovered by PANSTARRS (PS1) on May 21, 2017 at a distance of 16.09au. The comet will come to Perihel in December 2022. We have described this comet several times already. Last six months ago. The comet was a record when it brightened very far from the sun, it has been compared to the Hale-Bopp comet in 1997, source Wikipedia . When filming the comet was 5,389au away, the closest it will be 1,819au on July 14, 2022. 1Picture...

Jari Kuula, Porin Karhunvartijat

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.
