Sun

25.6.2022 at 15.10 - 15.40 - Suonenjoki (III)
Vesa Vauhkonen, Sisä-Savon Ursa

Midsummer Sun in Tyyrinmäki. In light and white, white and colored. Larger comma group with digizome. Quite a normal situation.

Pollen corona

10.6.2022 at 22.38 - 22.42 - Rautalampi (IV)
Vesa Vauhkonen, Sisä-Savon Ursa

The pollen rings of pine are quite spectacular in Joutenlahti near Kerkonkoski. The best for me this summer.

Pollen corona

Vesa Vauhkonen, Sisä-Savon Ursa

Pollen is abundant in the air and also in the eyes, mouth, nose and ears. The light-colored Oumuamua also happened in the first picture.

Sun

24.5.2022 at 13.40 - 14.40 - Suonenjoki (III)
Vesa Vauhkonen, Sisä-Savon Ursa

On Tyyrinmäki again, sifting the sun. That bigger group of dots is spinning behind the puck. ROI-delimited, to-taste-colored. GIF animation from the edge of the How-to tube. Weak promotions, maybe some kind of starting protukin. It had to be overexposed to get exposed. I will continue with a section on the entire view of the view.

Sun

22.5.2022 at 16.00 - Suonenjoki (III)
Vesa Vauhkonen, Sisä-Savon Ursa

Even more commas are noticeable again. The largest number is 3014.

Moon

11.5.2022 at 21.30 - Rautalampi (III)
Vesa Vauhkonen, Sisä-Savon Ursa

The moon as before at this point. Mosaic of 6 stacks. A bit of a 'sloppy' backdrop.

Sun

8.5.2022 at 13.37 - Suonenjoki (III)
Vesa Vauhkonen, Sisä-Savon Ursa

The sun only appeared from time to time from the holidays of the clouds on Tyyrinmäki. The image is built from about 320 frames of AVI video.

Primary rainbow

2.5.2022 at 20.08 - Rautalampi (III)
Vesa Vauhkonen, Sisä-Savon Ursa

A short rainbow in a gentle breeze. Main image with right camera, second image with phone.

Sun

24.4.2022 at 14.03 - 15.10 - Suonenjoki (IV)
Vesa Vauhkonen, Sisä-Savon Ursa

Solar observations at Tyyrinmäki Observatory. The weather was clear but the wind was incredibly cold. The first two images in white light: Astrosolar film, 9.25 '' Celestron SCT. Images: Lunt LS50 THa, with simple filter. Current main observation system. Power sharing and USB on the same hub (Pegasus Astro Advanced Pocket Powerbox). Quite an incomparable device.

Moon

12.4.2022 at 20.50 - 21.20 - Rautalampi (III)
Vesa Vauhkonen, Sisä-Savon Ursa

The terminator of the Filling Moon looked so comfortable in the eyepiece that I had to put a planetary camera in place of the eyepiece. A mosaic of five images, each 10-15% of the best stack of 1000-2000 video frames. -I try to avoid over-sharpening, which easily leads to an 'inventive' surface texture.

IC 63

22.3.2022 at 22.44 - 03.40 - Rautalampi (I)
Vesa Vauhkonen, Sisä-Savon Ursa

The Ghost of the Cassiopeian proved to be quite difficult to describe. There is such a low surface brightness. Exposure for more than 4 hours with a color camera.

M51

22.3.2022 at 21.03 - 23.58 - Suonenjoki (II)
Vesa Vauhkonen, Sisä-Savon Ursa

NINA is now also in use at the Tyyrinmäki tower. The first (experimental) sequence with this stock. Seeing was moderate. Target high.

Moon

14.3.2022 at 19.30 - 20.30 - Suonenjoki (III)
Vesa Vauhkonen, Sisä-Savon Ursa

Third night in a row in Tyyrinmäki with a bouquet of the moon. This time the targets are Rainbow Bay and the craters Cassendi and Copernicus. Especially digging Copernicus ’interior tools is challenging with these devices.

Moon

13.3.2022 at 19.25 - Suonenjoki (IV)
Vesa Vauhkonen, Sisä-Savon Ursa

The lunar exercises continue. Lahti and Jura mountains of the rainbow.

Details of the moon in Tyyrinmäki. Montes Apennines, Clavius et al.

IC 405

4.3.2022 at 20.27 - 00.29 - Rautalampi (I)
Vesa Vauhkonen, Sisä-Savon Ursa

Fog of a blazing star. Sequence pre-programmed (NINA). Remote phone access from Kuopio (Chrome). Seeing can only be deduced from the pictures when I was not present. -The end of the sequence is a telescope in the park and pictures in a jar. - Oh, if only you could get started with PixInsight. I downloaded the free trial, I should start studying the tutorial videos.

M78

3.3.2022 at 20.08 - 00.13 - Rautalampi (I)
Vesa Vauhkonen, Sisä-Savon Ursa

This fog already seemed a bit more demanding. Equipment for remote access by phone (Chrome Remote Desktop app). NINA

NGC 4565

3.3.2022 at 00.52 - 03.12 - Rautalampi (II)
Vesa Vauhkonen, Sisä-Savon Ursa

'Needle Galaxy' in Berenike's hair. Again pretty good seeing, the moon didn't bother me. 550 mm focal length a bit unnecessarily small for this target.

Markarianin Ketju

28.2.2022 at 22.57 - Rautalampi (II)
Vesa Vauhkonen, Sisä-Savon Ursa

Markarian chain again. I have photographed before with Newton, now with an apochromat. Good seeing. The cable remote control worked flawlessly. NINA

Leo Triplet

26.2.2022 at 00.46 - 03.21 - Rautalampi (II)
Vesa Vauhkonen, Sisä-Savon Ursa

The lion is comfortably in the hall again after midnight. Here's one view of Triplet.
