Jukka Koivisto, Suomenselän Pegasus

A pair of companions to the Andromeda galaxy, the dwarf spheroidal galaxies NGC 185 and NGC 147.

Telescopic comet ATLAS

27.12.2021 at 22.20 - 22.40 - Alavus
Jukka Koivisto, Suomenselän Pegasus

When the more handsome comets always go there in the southern hemisphere, then these smears are described. I only have 4 x 5 mins to take before the arrival of the cloud.

A fireball at night, brighter than the venus

5.12.2021 at 17.30 - Alavus (III)
Jukka Koivisto, Suomenselän Pegasus

As I drove, I noticed a fireball in front of me. Slightly brighter than Jupiter. It progressed in the southern sky towards the southwestern horizon. Progress was quite slow as the car camera video shows its first appearance at 17:30:43 and the last glance at 17:30:49. It went annoyingly behind the tops of the trees and I couldn't push it all the time while driving. It just disappeared behind the trees near the horizon, I didn’t see any glare or flashes. Pictured is the first view in the camera.

Mars ja Plejadit

5.3.2021 at 20.30 - Alavus (IV)
Jukka Koivisto, Suomenselän Pegasus

After a long dry season (bad weather), shooting with some new equipment. This encounter is the first image born. The 300mm tube was a bit cramped for these but when the zoom was inside the temperature then this is a satisfaction.

Rare halos

24.6.2020 at 12.03 - 12.45 - Alavus (IV)
Jukka Koivisto, Suomenselän Pegasus

During a telecommuting day, I turned out to see what was going on. I glanced at the sky and immediately hit the eye in the northern sky with a horizon ring. I haven't seen it in a while. I examined what else is visible but none other than the 22 ring and the 22 top side. I picked up the camera and raped some pictures. I watched with the plane and adjusted it a bit, so a solar arc popped out of it, I ended up in Wegener. I didn't see it with the naked eye or the mirror. A more ingenious image processor would probably know how to dig that arc better.

Telescopic comet ATLAS

14.3.2020 at 21.15 - Alavus
Jukka Koivisto, Suomenselän Pegasus

In a slightly awkward place, this comet housed near the zenith but I managed to persuade the systems in that direction.

IC 443

22.1.2020 at 22.15 - 23.45 - Alavus
Jukka Koivisto, Suomenselän Pegasus

The first attempt to compile and process the image with Pixinsight was difficult but I got some sort of thing done. In the picture you can find e.g. IC 443, Sh2-249, IC 2156, IC 2157, NGC 2158 and M35.

Telescopic comet PANSTARRS

2.12.2019 at 20.50 - Alavus (I)
Jukka Koivisto, Suomenselän Pegasus

How black it feels that before comets were bigger and more spectacular. Now there are only small stains that I can't even find in the picture.

Starry sky image

29.10.2019 at 23.20 - Alavus
Jukka Koivisto, Suomenselän Pegasus

It features a portrait of the newly named Suomitähti (HAT-P-38). Horna called, Hiisi does not appear in the picture.

Telescopic comet Iwamoto

21.2.2019 at 19.35 - 20.35 - Alavus
Jukka Koivisto, Suomenselän Pegasus

When there is a clear evening and a moment to describe before the rise of the Moon then this comet must be immortalized before it disappears into the emptiness of space. Average and median stacks in the pictures. So dim that it didn't stand out with its binoculars.

Rare halos

19.1.2019 at 10.55 - 12.10 - Lapua (IV)
Jukka Koivisto, Suomenselän Pegasus

There was already a clear ice mist play! The brightest sails that have never been seen but don’t really look like anything in the pictures. The ice mist came from the snowfall of the Simpsiö ski slope. 18 degrees below zero. No other halos appeared than those in the pictures. What shape brings the vertical “side sun” of the last image I don’t remember seeing on such a column? Would Schulthess be an arc?

NGC 2174, IC 443

2.1.2019 at 21.40 - 23.10 - Alavus
Jukka Koivisto, Suomenselän Pegasus

Again, one item on the shooting list is captured. At least tentatively, more light could still be collected.

NGC 1499

29.12.2018 at 19.30 - 20.15 - Alavus
Jukka Koivisto, Suomenselän Pegasus

Headlights from California fog. You can't get married from these unmodified cameras, but something like that when you tear enough. These winter skies but sheds to be so bright that the 2 minute exposure was pretty maximum.

Binocular comet Wirtanen

29.12.2018 at 19.00 - 19.25 - Alavus (II)
Jukka Koivisto, Suomenselän Pegasus

After more than three weeks of full cloud, it was finally a relatively bright evening and not a moon as a nuisance. Wirtanen still somehow visible. With binoculars as a weak foggy, from whom no comet would have been recognized if he had not known.

Binocular comet Wirtanen

5.12.2018 at 22.00 - 22.20 - Alavus (II)
Jukka Koivisto, Suomenselän Pegasus

There was a clear sky when I left work. In it, I then tuned the equipment to the comet waiting and suddenly the sky pulled into the cloud. In the rain I carried some of the goods inside. From the satellite images, I thought there was a small cloud ferry that should soon pass and that’s what happened. The stuff is back in working order and so that comet is now immortalized. With the naked eye, I didn’t notice but the binoculars showed up as a wide foggy.

Barnard 150, NGC 6946, NGC 6939

3.11.2018 at 18.30 - Alavus (I)
Jukka Koivisto, Suomenselän Pegasus

The clear evening did not last long as the fog already took over the skies. But little did I get to describe the subject of the evening. A bit of an awkward target right in the zenith.

Telescopic comet Swift-Gehrels

14.10.2018 at 23.30 - 00.10 - Alavus (I)
Jukka Koivisto, Suomenselän Pegasus

At the end of the shooting session, I remembered to make this comet visible to the shooting location, so I tried to grab the cell and grab it somehow.

NGC 7000

14.10.2018 at 21.00 - Alavus (III)
Jukka Koivisto, Suomenselän Pegasus

The result of four shooting sessions (September 14-14, 2018) from the North America fog.

Binocular comet Giacobini-Zinner

16.9.2018 at 03.30 - Alavus (II)
Jukka Koivisto, Suomenselän Pegasus

In the morning hours under the still sky it is good to describe. Only the pearl owl roared in the woods. In addition to the comet, the image also includes M35, NGC 2156, NGC 2157, NGC 2158, and IC 443. The stacked image was nowhere near as good as this single exposure.

NGC 7000

14.9.2018 at 23.25 - 23.45 - Alavus (III)
Jukka Koivisto, Suomenselän Pegasus

The evening was pretty clear, so I wanted to retake yesterday's Pluto but there was so much cloud on the horizon that it didn't become anything. I then photographed something like this North American fog.
