My meteor camera detected a bright fireball last night. The fireball had a duration of exactly 5 seconds. There is also a video of the fireball.

The sky camera on the balcony captured the maximum stack for half a minute of this bright fireball. The fireball had time to disappear behind a neighboring house before going out. In addition to the maximum stacks, the fireball camera software made by Panu Lahtinen collects separate timing images, from which I was able to measure the duration of the visible part of the fireball from 3.0 to 3.5 seconds.

In the early evening, all the northern lights forecasts were in red, and I left for nearby Patterimäki with the camera at about 19:35. As soon as I stepped out the ladder door, despite the glow of the street lights, I saw bright northern lights in the northern sky, even though the sky was still bright at dusk. I would run around to get to a slightly darker spot before the northern lights fade. At the top of the hill I still had time to see a bright warp for a while and I even got a few pictures. Seeing the bright northern lights from the pale evening sky was an impressive experience. The occas...

Oh boy! Today I saw the brightest horizon ring I have ever seen, and clear 120 degree side suns. Halo appeared all day. I used halos from the office roof all day. In the morning only 22r, 22ys and 22as were visible, but at noon a bright horizon ring began to appear, which remained in the sky for several hours. I tried to look at Wegener and other rarities that had been observed elsewhere in Finland, but nothing was visible. Handsome anyway! I already saw a few halo shapes when I left home, and I made a separate observation of them.

We were with Susanna Taivalsalmi, Lauri Kangas and Tuure Laurinoll to observe a complete solar eclipse in Gallatin, Tennessee, USA. At least Lauri will still make his own observation of the Sky Guard. The day before, Lauri and I went to look for suitable observation sites for the eclipse. Our place to stay was in the blackout zone, but by traveling closer to the center line, an eclipse lasting up to 20 seconds was achievable. The best candidates seemed to be either Springfield or Gallatin. Based on the weather forecasts for the darkening morning, we ended up leaving for Gallatin. Severe conges...

On the last night of the trip to Tenerife, handsome almond clouds appeared over the roads, which remained more or less visible for several hours.

Jari Saukkonen and I went to Oittaa in Espoo on the shores of Lake Bodominjärvi to originally spot the NEOWISE comet, but before midnight the illuminating night clouds covering almost the entire sky stole the show. Initially, especially in the west, very bright fibrous night clouds were visible, in which gravitational wave-like horizontal stripes also stood out (see last figure). On the west side, however, the night clouds faded in less than an hour and the rest of the play focused most on the northern and northeastern skies. On the way home, clear night clouds were also visible in the very so...

The observation shelter I used on Kirkkonummi's Komakallio is still under renovation, so instead of shooting through a telescope, I had to come up with something else to do. I followed a wide picture of the Milky Way with the help of a fisheye lens. There is a total of 19 x 2 minutes of light in the image.

On Saturday the weather became clearer again and I was able to shoot at Komakallio in Kirkkonummi. I had photographed Orion's gas fog at the beginning of the hobby, but after that I was left with the urge to photograph the subject with sometimes better equipment. Now I finally got a somewhat valid picture of the subject. The temperature during imaging was about -15C.

Good shooting conditions have pampered Southern Finland, and last night I exposed this fog complex in Kefeus for about four hours.

This winter, good weather has been rare. However, I photographed this subject as well on 26.12. that yesterday, 5.1. The last night there were filming slightly disturbed by the full moon. I compiled the images using PixInsight, a mosaic of such two screens. The target is a large emission nebula in the constellation of Cassiopeia. The subject is often also called the Soul Mist, or Baby Mist. The image field is about two degrees wide in this mosaic. I connected the observation to both the SII + Ha + OIII color image and the Ha image alone. Larger versions of both images can be found on Astrobin:...

I started filming this old familiar subject as early as the December side, but most of the exposures came to be collected last night. The image is a two-frame mosaic, and both halves have about 2 hours of exposure.

We were in a small group of star photographers in Tenerife for a week. On Wednesday-Thursday night, a layer of central clouds covered the light pollution of coastal cities, leaving Teide National Park particularly dark. The Milky Way shone magnificently in the sky and several objects from the deep sky were visible to the naked eye. We were in the park shooting until five in the morning. Here are the best landscape stars from us that night.

The shooting season has finally opened with the new Skywatcher Esprit telescope. The night sky is still relatively bright, but so bright that hydrogen emissions can already be captured with a narrowband filter. Pictured is the classic North American fog NGC 7000.

The nights are starting to get so dark again that with clear weather, you have time to illuminate for several hours a night. I photographed the North American fog NGC 7000 over two nights for a total of 5.5 hours. I’m still learning how to use the new Esprit 100ED telescope, but so far I’ve been very happy!

I photographed this classic object, the Andromeda Galaxy, again after switching from a telescope in the summer to a short-focal lens telescope. Despite the short focal length, the subject did not fit completely in the camera cell, but the subject is depicted as a mosaic. The image consists of four smaller images. The subject has been exposed for two nights in September-October, but due to other hustle and bustle, processing was not left until December. A strange bulge appeared around the brighter star next to the galaxy, probably due to the moisture in the optics.

I photographed Orion's large gas fog from the Komakallio remote observatory on both sides of the turn of the year on a total of five different nights. There is a total of 11 hours of exposure in this image, so the image is not the longest project of this season, but clearly the most challenging to handle. The image is a two-part mosaic, and I photographed both short and long exposures of the subject. Without such gimmicks, the brightest parts of the fog would burn helplessly. I’m still not completely happy with the colors in the picture, but I’ve been delaying the release of the picture fo...

During the summer, I switched a notch to a larger star camera, and finally got to take the official first light with it. I targeted the classic North American fog, which is very hollow this fall. With the new camera, the field of view is so wide that it can also accommodate the adjacent Pelican Mist, i.e. the IC 5070. In addition to the full view, I added a couple of details in 100% size to the observation. The other little bit sadly left a small satellite chip that I missed during the stacking phase, and I no longer wanted to leave to do the whole processing again because of the Streak.

The fog of Orion and its surroundings will not be visible to Komakallio in Kirkkonummi for a very long time at a time, so I photographed this subject on four different nights. The image is a 3-part mosaic, and each part is exposed for a total of about 4 hours. At the bottom left you can see both the Flame Nebula NGC 2024 and the Horse Head Fog IC 434, and at the top right you can see Orion's large gas fog M 42.
