Deep space

This dichotomous planetary nebula was visible in an incredibly abundant star field, where dark mist also stood out. There are indeed objects of this type in the constellation Kotka no matter how.

This insignificantly sized planetary has much the same thing as Lifting Weight Nebula, although the sides that are dimmer than the center look the most diffuse.

This subject would probably be described less if it didn’t have such a teasing smoothing. The lens galaxy called Mirach's ghost was not quite symmetrical. A slight darkening was visible on its left edge.

NGC 246

4.9.2021 at 03.33 - Orimattila, Artjärvi, Tähtikallio (II)
Toni Veikkolainen, Keski-Uudenmaan Altair

This fog, wide in diameter and dim in surface brightness, was the last subject of the night. The shooting of the colors was not successful due to the cloudiness so I was content to take the luminance alone into the final image. Gotta try again in better weather.

1585 Union (1929 DB, 1937 QF, 1939 CD1,1944 DG, 1947 RG, 1949 EE, 1952 QA1,1952 SD) The asteroid on the outer edge of the main zone was imaged on the second night of the September 2021 work. The asteroid was discovered by South African astronomer Ernest Leonard Johnson at the Johannesburg Observatory (078) on September 7, 1947. Ernest Johnson has found a total of 18 asteroids and comets C / 1935 A1, C / 1948 R1, C / 1949 K1, 48P / Johnson. source Wikipedia . The asteroid is named after the Union Observatory in Johannesburg, South Africa. Sou...

Reflected sunbeams

23.9.2021 at 08.33 - 08.46 - Kontiolahti (II)
Marko Riikonen

Spots of cloud rays reflected in the morning on the lower surface of the cloud when there was a suitable clear gap below. I took a series of pictures just in case the haa appeared. But often they snuggle up to appear without hps. Apparently I also became warm by making images of the ground that is at the time of observation at 5s intervals.

22.9.2021 at 00.00 - 03.00 - Kangaslampi (III)
Erik Pirtala, Warkauden Kassiopeia

I finished the tulip mist I had long and earnestly exposed. Since the beginning of September, I have taken advantage of twilight and full moon hours (even a little dark) for 15.5 hours. H-alpha came by far the most (7.7) hours. Oxygen and sulfur channels remained weaker. The stars are again described separately with RGB filters. In other words, a familiar technique to yourself with a new item. The tulip itself was pretty fun to handle. For me, the salt of the species is such bright golden mist areas. The dimmer mists in the background were then more challenging because they didn’t really conta...


22.9.2021 at 20.55 - 22.10 - Rautalampi (III)
Vesa Vauhkonen, Sisä-Savon Ursa

At the Tyyrinmäki Observatory following Ion's movements. The height of Jupiter was only about 9-12 degrees, that is, without the dispersion equalizer, imaging would not have become anything at all. Now the shadow stands out clearly and also the shift of the moon itself from the front of the planet to the right at the end of the animation.

Glory on air

23.9.2021 at 05.15 - 05.45 - Juva (III)
Petri Martikainen, Ursa (Itä-Suomi)

I woke up at five in the morning and went hunting with a drone on the Moon. The attempt of the previous morning had crashed to the rocks right from the start, when the drone refused to ascend, but demanded that the compass be calibrated. Well, I couldn't do it in the dark without a manual. Fortunately, the trouble later recovered on its own. This time there were no problems with the drone, but the dilemma was to find a decent fog. I set off to drive to the destination I was thinking about in advance. Already a couple of miles away was the first fog ferry over the road. I stopped at it and ...

Active aurora band

10.9.2021 at 00.30 - 03.00 - Valtimo (III)
Eero Karvinen

The calm storm surprised with its beauty. A series of images of the westward wave of a substorm. The brightest phase in the main image, the other images in chronological order. At the beginning of the substorm, a false start was seen, which can be characterized by the disintegration of the oval into parts and their reunion into a calm diffuse arc before brightening.

Several halo forms

22.9.2021 at 10.48 - Ikaalinen, Sisättö (II)
Heidi Rikala, Ursa (Helsinki)

Now it seems to be the most versatile halos of the summer season that I have spotted. mm. 46 ring and ZYK. Of that 46, I'm still not sure if it's a side-arch or a ring? Quite a nice play that didn't last very long. #bongaa100.

NGC 6820, NGC 6823

Vesa Puistovaara, Porin Karhunvartijat

 Tähtijoukko NGC 6823 on sumun NGC 6820 ympäröimä. Kuvassa sumun näyttävimmän kaasupilarin osoittamassa suunnassa oleva avoin tähtijoukko syntyi noin 2 milj. vuotta sitten, ja se muodostaa ympäröivästä materiaalista uusia tähtiä. -- (lähde: Nasa -

Quiet aurora arc

Heidi Rikala, Ursa (Helsinki)

Your intention was to take hard when you once again pulled the sky into the cloud when the northern lights forecasts were in good shape. I thought that even today I would see nothing but a cloud. Then I went to the sauna house, and in the meantime the clouds had receded and the north was open. Jee! does not change when I back out. I had to wait another hour, before the northern lights appeared. The bright moon made it a little awkward when the sky was a little too bright. Well, anyway, I got the repos I expected to be photographed. At first they looked pretty bright, then dimmed into a mere ar...

Kuun kehä

21.9.2021 at 21.30 - Ikaalinen, Sisättö (III)

Täysikuu kipusi puidenlatvojen yläpuolelle pilvissä olleen kehän kera. #bongaa100

Yksi halomuoto

Kuun sivuaurinko näkyi matalalla olleessa pilvessä. #bongaa100

Lähes täysikuu oli kirkas ja näkyi pienikokoisena, koska oli kaukana Maasta. #bongaa100

Surprisingly, a colorful side sun appeared and then another 22 tires upside down. #bongaa100

One halo form

Already in the morning in Turku dim 22r but it was only properly visible in the afternoon when the trip to Utö came to Jurmo.
