Binocular comet

Petri Kuossari, Riihimäen tähtit. yhdistys

Luckily I didn’t believe the weather reports and I put a tube to cool out the night before going to bed. The clock was waking up at four in the morning, a glance out the window and a positive surprise as the stars appeared in the sky. Quick dress and 12 degree frost to align the tube. With Bakhtinov's mask, the Arcturus star is focused and the comet Leonard is bursting from the thrill. Wow that's it now with a wonderfully open ball set M3. I take 1-2 minutes of exposure for about half an hour until I take out the Optolong L-Pro filter and continue for another half hour I was still comp...

In the morning I photographed comet C / 2021 A1 Leonard and in the evening it was M1 crab fog. The bigger picture also shows the small planet 857 Glass Button. From this I made my own observation to the star of the sky.

In the morning I photographed comet C / 2021 A1 Leonard and in the evening it was M1 crab fog. Coincidentally, the little planet 857 Glasenappi came into the picture. The orbit of this around the sun is 1183 days. 857 Glass button is also made into a 3d model https://3d-asteroids.space/asteroids/857- Glass button

M87

26.11.2021 at 05.50 - 06.00 - Tervakoski, Janakkala (III)

The M87 also got lost in front of the tube with a short exposure. The last image is a combination of dozens of individual images from the Unistellar community. The superimage features a relativistic shower radiating from a supermassive black hole in the core of the M87. The M87 galaxy is interesting because it is the first black hole ever photographed by humans. Event Horizon Telescope now took the iconic image of the M87 * black hole in 2019 using telescopes around the world. A relativistic shower from the center of the black hole also appeared within minutes

Leonard was perfectly visible in the morning despite the moonlight. Hopefully there will be more clear weather by December. This can become a spectacular target if the predictions hold true.

The main focus of the evening was the Asteroid 2002 AW34 crossing, which I noticed and the result was negative. After scientific work, I decided to test a new optolong L-Pro filter, pictured with a horsehead mist

Petri Kuossari, Riihimäen tähtit. yhdistys

On Monday night, I photographed the Asteroid 980 Anacostia overpass to the Seti Institute, would look like positive observations. This finding led to more detailed research at the Seti Institute as a researcher by Joe Asencio. In a month, I will probably get more accurate data on the overrun.

I promised to send more detailed information about the overflow of asteroid 980 Anacostia when I get the results from the Seti Institute. The picture shows the data from the analysis. Anacostia was covered by a magnitude of 10.5.

Skyscrapers drifted in the sky at a steady pace and I wondered twice if I would take the telescope out, I wouldn’t. However, I went out of heaven to admire. On the phone, I grabbed this mood picture as the mist began to rise from the horizon. In the second picture Jupiter and a cloud ferry.

On the first day of October, on Friday, I received an alert in the slack group about the comet 29P / Schwassmann-Wachmann brightening. The first opportunity to observe came surprisingly quickly despite the weather reports was clear. The comet appeared handsome right on the screen and a short exposure was enough.
