Moon

Ari Haavisto, Ursa (Länsi-Suomi)

Seeing and transparency did not really allow for a detailed description, but I still recovered the materials of the whole mosaic of the Moon. The full size image can be viewed from this link: Link to the mosaic image

From this, a couple more broad views of the southern and northwestern blocks of the Moon, as well as the entire Mosaic of the Moon, assembled from slightly varying materials. Full size images can be viewed via the links below. The size of the mosaic is about 100 Mpix, scaled down according to the weather. The Southern Moon Northwestern block Mosaic of the whole Moon

Ari Haavisto, Ursa (Länsi-Suomi)

A small potpourri of the details of the surface of the Moon and at the same time the first attempt on the Moon with a new tube. The results are promising for the weather. Being the first in Rainbow Bay in a different orientation, the edge cliffs look pretty steep! Then Tyko and lastly a bigger picture area of the Ptolemaeos trio. To view full size most images need to be viewed via the link below: Rainbow Bay - link to full size Rainbow Bay, another orientation, link to full size Tyko, full size Ptolemy trio with surroundings, link to full size

Jupiter

6.8.2021 at 01.50 - 02.45 - Lempäälä (IV)
Ari Haavisto, Ursa (Länsi-Suomi)

Io and his shadows pass in front of Jupiter. A large red dot is also on display. Jupiter in RGB image at 2.40. Another image of the same, but sharpened with an infrared channel image. The color channels described in the third are separately, from which the color image is assembled. In the fourth situation at. 1.58.

Beautiful Saturn on a summer night.

Ari Haavisto, Ursa (Länsi-Suomi)

Jupiter is already rising a little off the horizon-shaking embrace, but this time was more severely disciplined by seeing than Saturn a moment earlier. It was nice, however, to greet an old friend.

Ari Haavisto, Ursa (Länsi-Suomi)

Sailing on the waves of the summer night horizon, Saturn was honored to be the headlight of the new tube. It has not yet received a very strange picture through the thick air mass, but from this it will only improve in the next few years.

Koko Kuu

Ari Haavisto, Ursa (Länsi-Suomi)

The whole growing crescent moon as a large mosaic, perhaps photographed in the best weather and lighting so far. The mosaic can be viewed via the links below. It may take some time to load the image and open it to full size. Even in JPEG format, that full size is almost 50 Megabytes and over 170 Megapixels ... 75% full size version: https://astruvat.kuvat.fi/kuvat/Kuu 2021 / Mosaic_19042021_2051_75bright.jpg? Img = full And a 100% full size mosaic: https://astrunnot.kuvat.fi/kuvat/Kuu 2021 / Mosaic_19042021_2051_100bright.jpg? Img = full Another detail of the observation is the Janssen crater

Moon

Ari Haavisto, Ursa (Länsi-Suomi)

I got to practice making mosaics again. The background sky was still bright and seeing was throwing, so the handling was challenging and took an entire week, still leaving much room for improvement for the future. But a nice 225 Megapixel sickle was finally born from it. Attached to the observation is a mini version and larger links below. The full-size image can be accessed from this link: 225Mpix mosaic And a 65% sized smaller version, the 100Mpix can be found here: 100Mpix mosaic

Ari Haavisto, Ursa (Länsi-Suomi)

For a long time a moment bright and the Moon visible, so I tested a new combination of mosaic photography. The sky started to darken and the weather was throwing, so image processing became what came. But there is enough to explore. Attached are thumbnails for previews and larger versions can be found here behind the link and from there by clicking fully open: Reduced version of the 20 megapixels: https://astrphotos.kuvat.fi/kuvat/Kuu 2021 / Moonmosaic_17022021_vaaka_35.jpg? Img = full A reduced version of 85 megapixels, this too can still be viewed at least in some places: https://astrphotos....

Mars

Ari Haavisto, Ursa (Länsi-Suomi)

Here, as a follow-up observation, a few rarer objects, mainly craters, were identified or attempted to be identified from the image of Mars the second night 04.26. You will probably need to click open on the animation image for the animation to display properly. Same as still images. Edit 7.10: I added a few images when I got a little more resolution to the images through deconvolution.

Mars

Ari Haavisto, Ursa (Länsi-Suomi)

Keli surprised the graph, this time positively. Especially on the ir channel, Mars was filled with detail and allowed for the combination of good color images. I shot with a slightly longer shutter speed and lower gain to capture sensitive details. During the recording of the videos, I also did small microfocuses on the focus so that at least some of the screens would hit the best focus.

A few IR-RGB images of Mars from last night, as well as an instantly twisted animation of them. Still, decent seeing lets wait for itself.

Mars

Ari Haavisto, Ursa (Länsi-Suomi)

Now Mars has already agreed to reveal a little of his secrets during a valid infrared session. The areas of Mare Cimmerium are nicely displayed there. Edit: Almost in the middle of the Martian disk, two thin dark promontories “hang” down from the dark Cimmerium. Farther from the headlands is the Gale Crater, where Curiosity conducts its research. The crater is the width of the headland, i.e. it is practically visible in the pictures, although it does not stand out.

Mare Cimmerium with dark "horns" in that middle, Syrtis Major turning visible on the right and right at the bottom in bluish looms Utopia Planitia, if there were clouds there too. Among the poor seeing, a couple of short, smoother moments were found. In the first picture, the RGB channels are pretty good and steeled with IR. In the second luminance mostly ir.

Twinkling between the cloudless Mars. Infrared 87% weighted RGB image.

Still, the seeing is soft and the live screen of Mars is like a burning flame of rusty iron. But with brute force and an ir-pass filter, some details can already be seen.

Ari Haavisto, Ursa (Länsi-Suomi)

Poor seeing has plagued my Mars filming attempts so far. Now with Mars still low, the weather looked promising in the early night test images, until a surprise cloud cloud emerged directly above the clear sky and remained motionless to cover much of the sky. After wondering for an hour on the cloud board and finding that it wasn't going anywhere, I had to give up the filming again ... But it looked quite promising until then.

Saturn

8.8.2020 at 00.01 - 00.04 - Lempäälä (II)
Ari Haavisto, Ursa (Länsi-Suomi)

Saturn plows the southern horizon at a height of 7 degrees like a majestic sailing ship, sending its faint reflection diagonally across a thick and stormy sea of air. In comparison, I am happy with my picture as I look forward to better shooting years to come.

Jupiter

Ari Haavisto, Ursa (Länsi-Suomi)

Jupiter photographed only from a height of 6 degrees. Surprisingly, however, something can be seen from there.
