NGC 7000

21.11.2021 at 21.30 - 23.30 - Rautalampi (II)
Vesa Vauhkonen, Sisä-Savon Ursa

The subject of the stock test is North American fog. Very bright moonlight, which brought an additional challenge. NINA, remote control over the network with TeamViewers on another computer. Unfortunately, the smoothing images were not taken, so there are a couple of bigger stains in the main image. But the details are still nice to find. 45 x 120 sec.

M31

8.11.2021 at 19.43 - Rautalampi (II)
Vesa Vauhkonen, Sisä-Savon Ursa

The picture is not strange, the exposure is only 3 x ½ minutes. In the test NINA, an absolutely awesome imaging application with Plate Solvers (ASTAP). Fill image of a courtyard observatory (sky as a roof).

NGC 6992

2.10.2021 at 22.10 - 23.20 - Rautalampi (III)
Vesa Vauhkonen, Sisä-Savon Ursa

The eastern branch of the gauze fog under good seeing. Exposure only 63 min, no calibration images. The colors were a bit awkward to tune in. Let's strive for better next time.

NGC 5907

27.9.2021 at 23.40 - 02.30 - Rautalampi (II)
Vesa Vauhkonen, Sisä-Savon Ursa

A family galaxy with a mirror tube and a modified system camera. A challenging enough target in moonlight and high relative humidity.

Jupiter

27.9.2021 at 21.09 - 21.57 - Suonenjoki (III)
Vesa Vauhkonen, Sisä-Savon Ursa

Tyyrinmäki Observatory photographing Jupiter. The moon Ganymedes on the right in the first image casts its shadow on the edge of the planet. On the left 'shine' Io. In the second image, the shadow hits space. Quite a good seeing, although the relative humidity started to rise sharply as midnight approached.

Jupiter

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.

IC 1805, IC 1848

9.9.2021 at 23.30 - 01.20 - Rautalampi (III)
Vesa Vauhkonen, Sisä-Savon Ursa

This duo was chosen as the first DS destination in the autumn. Seeing was at a pretty good level.

Jupiter

8.9.2021 at 23.59 - 00.42 - Suonenjoki (II)
Vesa Vauhkonen, Sisä-Savon Ursa

The Red Dot observation window dawned again. Seeing was poor, and nothing really came of the stacked goods. However, there was so much work to put on display. Twisting in less than three quarters.

Moon

31.8.2021 at 00.40 - Suonenjoki (III)
Vesa Vauhkonen, Sisä-Savon Ursa

At the end of the planetary descriptions, we directed the tube to our orbit. Stacks of two videos glued with MsICE.

Saturn

30.8.2021 at 22.57 - 00.15 - Suonenjoki (II)
Vesa Vauhkonen, Sisä-Savon Ursa

In Tyyrinmäki, on the other hand, learning to use a dispersion equalizer. Our first somehow successful Saturn shot. There is also some detail about Jupiter. Composite of two stacked images.

Jupiter

28.8.2021 at 23.41 - Suonenjoki (III)
Vesa Vauhkonen, Sisä-Savon Ursa

At the Tyyrinmäki observatory, the subject is the testing of a newly acquired dispersion equalizer, targeting Jupiter. The result was a positive surprise. For example, the moon Io is drawn almost spotted. Clouding prevented the experiment with Barlow. Hopefully there will still be enough air.

Sun

27.8.2021 at 17.17 - Rautalampi (III)
Vesa Vauhkonen, Sisä-Savon Ursa

The sun also showed up. I tuned to the stand of an old super zoom with the Neutral Density Filter (attenuation 1/100000). As many as 10 image stack, 100% stack. The comma structures stand out reasonably well, even though the image is pretty much crumpled. Color and mv versions.

Perseidit

13.8.2021 at 00.15 - 03.00 - Rautalampi (II)
Vesa Vauhkonen, Sisä-Savon Ursa

The catch was modest. Three of the right sides of the composite image (shorter, longer bright and dim) come from the Persian radiant. The one on the left is probably sporadic. Planetary camera with mini lenses, 25 second shots. As a by-product, the first tour of the autumn and GIF animation.

Clearly visible night shining clouds

10.8.2021 at 23.25 - 00.30 - Suonenjoki (III)
Vesa Vauhkonen, Sisä-Savon Ursa

There are just enough of these. Phone picture directly from the phone from Tyyrinmäki tower. EDIT: Added a couple of images. Another from the fading phase, from the Toholahti bridge.

Jupiter

Vesa Vauhkonen, Sisä-Savon Ursa

Learned from Jupiter. Unfortunately, it clouded before the climax. Some details, little tonal differences.

Bright night shining clouds

2.8.2021 at 00.25 - Suonenjoki (IV)
Vesa Vauhkonen, Sisä-Savon Ursa

These just seem to be enough. Part of the pattern matured strikingly bright at times. At the Tyyrinmäki tower. By phone.

Janssen

28.7.2021 at 02.03 - Suonenjoki (III)
Vesa Vauhkonen, Sisä-Savon Ursa

Janssen crater with a declining lunar terminator. Pretty fun looking '' creature ''. From Tyyrinmäki tower.

Bright night shining clouds

Pretty nice night clouds again. Observations from the Tyyrinmäki observatory.

Jupiter

21.7.2021 at 01.43 - Suonenjoki (III)
Vesa Vauhkonen, Sisä-Savon Ursa

Jupiter and the moons from the left: Ganymedes, Kallisto, Io and Europa. About the imaging technology: One source video of 2350 frames, of which 10% is stacked as a source image with Registax. There are two treatments for this: First the adjustment of Jupiter and then the elevation of the moons, in the latter a burnt-out planet blackened in Photoshop. Merging: 1. Image Stacker on a 'brighter than' principle, 2. The Jupiter area is rocked in Photoshop to the right place with respect to the moon. Therefore, in the second image, the edge of the planet is less diffuse. On orthodoxy: the fi...

Eye-catching night shining clouds

21.7.2021 at 00.40 - 02.40 - Suonenjoki (V)
Vesa Vauhkonen, Sisä-Savon Ursa

Absolutely spectacular night clouds also at the height of the Suonenjoki. I haven’t stumbled upon such a great screen before. Panorama with phone, others with SLR camera. The GIF animator distorted the colors, but the movement of the clouds is clearly visible.
