Sun

18.5.2022 at 10.43 - Tampere (I)
Tapio Lahtinen, Tampereen Ursa

A day’s view of the sun and an hour-long timelapse picked up a quick eruption lasting about 15 minutes .

Telescopic comet PANSTARRS

11.5.2022 at 04.21 - 06.09 - Fregenal de la Sierra (I)
Tapio Lahtinen, Tampereen Ursa

I photographed this brightening comet with a Spanish telescope. At its brightest, this should be at the turn of next year. The brightness should then be about mag 8 grades. Unfortunately, this (even) comet is then in the southern sky.

UGC 9749 Ursa Minor Dwarf

11.5.2022 at 02.00 - Fregenal de la Sierra, Espanja (I)
Tapio Lahtinen, Tampereen Ursa

I’ve photographed some of these Milky Way dwarf galaxies and now in the spring I saw a picture of this rather challenging galaxy online. The distance in this dwarf galaxy is about 225,000 light-years. The galaxy is mainly made up of old stars and there is hardly any new star formation there. That’s why it’s so challenging when gas is no longer visible.

Supernova 2022hrs

10.5.2022 at 23.13 - 23.22 - Fregenal de la Sierra, Espanja (II)
Tapio Lahtinen, Tampereen Ursa

Monitoring of the supernova continues and dimming has begun

Supernova 2022hrs

9.5.2022 at 00.01 - 01.12 - Fregenal de la Sierra, Espanja (II)
Tapio Lahtinen, Tampereen Ursa

I took a slightly longer exposure from the supernova with a Spanish remote tube to get the colors and the galaxy forest captured.

Moon and Mercury

2.5.2022 at 22.20 - Tampere (III)
Tapio Lahtinen, Tampereen Ursa

With a small lineup, we gathered at the TaUrsa Tower to watch the encounter. The plateau was so windy that we moved pretty quickly indoors and out the window to wonder. At the time of imaging, Mercury was about 2.5 degrees away Before going to the tower, there was also a roe deer next to the tower for dinner.

Supernova 2022hrs

26.4.2022 at 00.33 - 01.32 - Fregenal de la Sierra, Espanja (II)
Tapio Lahtinen, Tampereen Ursa

The supernova has brightened 0.6 magnitude from the previous observation .

Nice activity again in protuberances. About an hour timelapse again

Sun

24.4.2022 at 11.00 - Tampere (III)
Tapio Lahtinen, Tampereen Ursa

After the normal surface image, I examined the protuberances and noticed movement on the western edge, and from there the material erupted into space. In the animation, a period of about an hour.

Tapio Lahtinen, Tampereen Ursa

Morning sun worship. I was at AhlmanEd yesterday for 3 hours on a solar screen and there were so many interested viewers that I got to invest more in solar observation myself.

6073 Tähtiseuraursa

22.4.2022 at 01.28 - 02.25 - Tampere (I)
Tapio Lahtinen, Tampereen Ursa

The intention was already to put the equipment on the summer rolls, but when a couple of days ago there was news of Väisälä's unnamed asteroid , this one too had to try to describe even though the night was starting to be light and the asteroid quite dim. Well somehow it shows and I even got the asterod brightness measured. Brightness mag 16.2 This became the Finnish asteroid I discovered at seventeen. #Suomi100asteroidit

Supernova 2022hrs

21.4.2022 at 23.45 - 23.59 - Tampere (I)
Tapio Lahtinen, Tampereen Ursa

I still had to stretch through to get this pretty bright supernova photographed. The host galaxy is NGC 4647 and the larger ellipse galaxy is M60

Sun

21.4.2022 at 16.40 - Tampere (III)
Tapio Lahtinen, Tampereen Ursa

So many handsome dots that I periodically make a mosaic.

M104

19.4.2022 at 02.30 - 03.30 - Fregenal de la Sierra, Espanja (III)
Tapio Lahtinen, Tampereen Ursa

Another ‘skeleton image’ of the galaxy photographed with a Ha filter.

M81 M82

19.4.2022 at 00.00 - 01.00 - Fregenal de la Sierra, Espanja (III)
Tapio Lahtinen, Tampereen Ursa

Sky model testing and galaxy imaging experiment with Ha filter. I call these pictures galaxy skeletons;).

Telescopic comet ATLAS

18.4.2022 at 23.23 - 23.59 - Fregenal de la Sierra, Espanja (II)
Tapio Lahtinen, Tampereen Ursa

Whether this comet was dimmed and the tail disappeared from the previous observation .

M64

18.4.2022 at 03.45 - Fregenal de la Sierra, Espanja (III)
Tapio Lahtinen, Tampereen Ursa

There has not been a picture on the Spanish tube since February (due to technical problems). When the moon was quite full, I tested the new sky model and the 10-minute unguided exposures worked quite well again. I tried to search for items from all over the sky and this was selected from the western sky. I have photographed the brightest galaxies a few times with the Ha filter and I doubted this ‘black eye galaxy’ would become any kind of image in this style. I was surprised when the characteristics of the object are visible so well.

One halo form

13.4.2022 at 15.10 - Tampere (I)
Tapio Lahtinen, Tampereen Ursa

In honor of the birthday, a donut coffee was held in Pyynikki. And the bag was in the sky.

Moon

12.4.2022 at 22.10 - Tampere (III)
Tapio Lahtinen, Tampereen Ursa

The moon is less frequently photographed with a CCD camera intended for the deep sky. Now that too was done when the season is coming to an end.

Several halo forms

Tapio Lahtinen, Tampereen Ursa

Halof April contribution. Stylish 22 degree tire and top side.

Search result contains observations from time period 1.1.2000 klo 00.00 - 22.5.2022 klo 6.47.
