Starry sky image

29.3.2016 at 22.05 - Kuusamo (III)
Voitto Pitkanen

Probably to be the last nights of this season, when you can still get something out of the starry sky with camera optics. The bear guard is also mostly in this picture taken with just over 3 minutes of follow-up.

NGC 4725

28.3.2016 at 04.00 - Kankaanpää
Tero Hirvikoski, Ursa (Länsi-Suomi)

Berenike hair rod spiral NGC 4725 photographed on the two nights of March. Extensive tidal loops stand out around the galaxy NGC 4747 visible on the left. The filming of both nights was rather weak due to the fog, the restlessness of the atmosphere, and the moonlight. Shooting dates were March 16, 17, 27, and 28.

NGC 4656, NGC 4631

28.3.2016 at 03.00 - Kauniainen (III)
Olli Arkko, Pollux, Aalto-yliopisto

Galaxies photographed from the slightly foggy sky at the end of the evening. There were flutter issues with the picture.


28.3.2016 at 01.50 - Jyväskylä (IV)
Sampsa Lahtinen, Jyväskylän Sirius

It became clear and a little time, so to the Nyrölä tower. Pretty turbulent seeing, but this somehow worked out, Cancer Nebula and Jupiter "spilled" on the jokes.

Antero Ohranen

There were signs in the repo forecasts that fire could be seen. I went to the filming site in good time, the mud did not show up properly, a little small reflection in the north. After the night, before, equally small Repos rays were visible. The stars looked really good, so it became a landscape star wax :-)

Atacan Ergin

I went to see what the sky looks like tonight. I took a landscape star photo and then at home I looked at Stellarium to see which stars were in the picture. The picture shows Jupiter, Procyon, Denebola, etc. I rarely do this but it was nice. Maybe you should do this more often. The same night I also went to photograph the northern lights .

NGC 5033

28.3.2016 at 00.30 - Ulvila (I)
Juha Ojanperä, Porin Karhunvartijat

We were with the active group of Pori Bear Guards to observe Ulvila Observatory on March 27/28, 2016. During the evening, our astronomers photographed Jupiter and a few deep sky objects, among others. Personally, I was able to visually detect the galaxy NGC 5033, a spiral galaxy discovered by William Herschel in 1785 in the constellation of Hounds. The galaxy is seen almost sideways and has a clear core. I could not detect the threaded branches. The weather was already pretty good, the air was relatively warm (around zero) and the sky was already quite dark because the snow had already melted ...

Exoplanet TrES-5 b

27.3.2016 at 23.25 - 02.31 - Tampere
Jouni Raunio, Tomi Hyvönen, Matti Koskinen, Tampereen Ursa

We re-described our first exo observation . This time, we were able to collect poorer and noisier observational data. The fitting routine gave an overflow duration of 116 min. (official estimate 111 min) and a pit depth of 18.2 mmag (official 20.6 mmag). Learn more about the place here and here .

IC 443

27.3.2016 at 23.00 - Kirkkonummi (III)
Samuli Vuorinen, Kirkkonummen komeetta

The last shooting nights of spring will be taken. IC 443, or Jellyfish Nebula, is a supernova remnant in the constellation of Gemini. A supernova remnant arises when a large star explodes at the end of its life cycle and leaves behind an expanding cloud of gas. The exact age of the fog is not known, but the supernova explosion is estimated to have occurred 3,000 to 30,000 years ago. The supernova remnant is about 5,000 light-years away from us, and its diameter is about 70 light-years. The picture has been exposed on two different nights, 21.3. and 27.3.

Jukka Hintikka

Despite the strong wind, I took a portrait of Misam, heart and soul mist.

NGC 2264

27.3.2016 at 23.00 - Kirkkonummi (IV)
Jari Saukkonen, Kirkkonummen komeetta

The shooting crests have already been put on the summer rolls, but the last unprocessed picture of the season was still found in the table box. I photographed this area of cone fog and Christmas tree set over several nights during March. The subject was already quite low on the western horizon, which is why the resolution of the image was not quite the usual level. However, a few hours of exposure produced a pretty good picture.

27.3.2016 at 22.00 - Maaninka, Patalahti (IV)

The zodiac light had to be left to admire the darkness of the Malainga Patalahti wetland, but the thinner cloud gauze remained tenacious in the sky until almost midnight. Well, on the other hand, the colors of the stars will be more prominent in the pictures when something is scattering light - even those clouds. The quadrangle would have the area of the zodiac light from the sky when it would have been at its best, yes it could be said to separate it from the clouds.

IC 405

27.3.2016 at 22.00 - Uurainen (II)
Jukka Hintikka

I screwed my camera to an old car in Chinon and tried what the driver's fog looks like through the cls filter


27.3.2016 at 21.47 - 21.56 - Kangasala, Sahalahti (III)
Jorma Mäntylä

Such an open constellation came to be described, has not hit the spot before.

Nova M31N 2008-12a

22.3.2016 at 20.22 - Hankasalmi, Murtoinen
Arto Oksanen, Jyväskylän Sirius

Negative observation for recurrent Nova M31N 2008-12a in the Andromeda Galaxy, which is expected to erupt on March 23 (+/- 11 days). This is the fastest renewable nova, with eruptions only 175 days apart. Even at its maximum brightness, the subject is extremely dim, about 18 magnitudes, and the eruption lasts only a few days. The next eruption is now being hunted in an intense international observation campaign, in which I, too, am participating within the limits of the weather. The purpose is to take a picture every clear evening and check if the nova is visible or not. A positive observation...

IC 1318

22.3.2016 at 02.57 - 05.05 - Tampere
Jouni Raunio, Tampereen Ursa

The first exposure of the observation night (a mist from the Sh2 list) went to the so-called to pepper even though the weather was quite moderate except for almost a full moon. But something was left in the evening, namely this second exposure of less than a couple of hours from the fog around Sadr's star. Full size image here .

Exoplanet Qatar-1 b

22.3.2016 at 02.04 - 04.46 - Tampere
Jouni Raunio, Tomi Hyvönen, Matti Koskinen, Tampereen Ursa

Qatar-1b is quite a popular destination among exo enthusiasts due to the short Transit and their frequent repetition as well as the comfortable depth of the pit. There was a bad timing of this observation but the actual time of the overrun hits the bottom of our pit very precisely. The fitting routine gave an overflow duration of 80 min. (official estimate 97 min) and pit depth 21.2 mmag (official 21.2 mmag). Learn more about the place here and here .

Variable star V808 Aur

21.3.2016 at 21.44 - 05.00 - Hankasalmi, Murtoinen (IV)
Arto Oksanen, Jyväskylän Sirius

One of my favorite targets, the polar variable V808 Aurigae (formerly known as OT_J0711 + 44). The target is a compact binary star in which a white dwarf is surrounded by a lighter red dwarf star from which matter flows onto the surface of the white dwarf. However, there is no accumulation disk around the white dwarf but the flow of matter is directed to the magnetic poles of the white dwarf under the direction of a magnetic field. An eclipse, repeated every two hours and deep in depth of more than two, occurs once the red dwarf has its orbit in front of a brighter white dwarf. Dimming and bri...

Exoplanet HAT-P-3 b

21.3.2016 at 21.34 - 01.35 - Tampere
Jouni Raunio, Tomi Hyvönen, Matti Koskinen, Tampereen Ursa

There was also a small timing inaccuracy with this observation. The fitting routine gave an overrun duration of 113 min. (official estimate 123 min) and a pit depth of 10.4 mmag (official 12.3 mmag). Learn more about the place here and here.

NGC 1664 Leijajoukko

21.3.2016 at 20.07 - Oulu (II)
Jaakko Asikainen, Oulun Arktos

As I dodged a roaring approach month in the East, I ended up filming an open crowd in NGC 1664 Driving Man. It is located 3700 light-years away in the emptiness between the Orion branch of our Milky Way and the Perseus branch. You can try to find the shape of a kite in the crowd, hint that in the picture the kite is upside down and held by a hot big star. For more information: Annotated image:

Jaakko Asikainen, Oulun Arktos

The first longer piece of the year rewarded bright weather with three images: one planetary nebula, one dwarf spheroid galaxy, and then such a more traditional individual. The M101 has been photographed with two other tubes, but I still wanted to see what kind of mark Newton would get. For more information:


19.3.2016 at 20.00 - Kajaani (III)
Kari Kauppinen

19.03.2016 Bright weather for two months ago, the light of the moon disturbed the exposure, but something caught the images in both. in it again, a hippopotamus and a flame mist, visible for about an hour in my backyard. You have to go for a picture in some dark pack if you are going to get a better track.


19.3.2016 at 04.30 - Kirkkonummi (IV)
Jari Saukkonen, Kirkkonummen komeetta

While the moon was hiding over another object under construction, another object had to be invented. The M101 ended up in sight, as it was as far away from the moon as possible in my sky and visible almost all night. I collected a total of 9.5h of exposure from this handsome spiral galaxy over two nights, and the end result was surprising! The hydrogen regions of the galaxy stand out clearly, and despite the moon, I also recovered some of the Milky Way’s own dust clouds, which stand out just from the background as the screen twists enough brightness. Note that you can no longer control it as i...

NGC 7000

19.3.2016 at 03.25 - 04.55 - Tampere
Jouni Raunio, Tampereen Ursa

Another target on Saturday morning was this fog classic. The arrival of spring will be noticed when filming is due to end in five countries already. Full size image here .


19.3.2016 at 02.45 - Kauniainen (IV)
Olli Arkko, Pollux, Aalto-yliopisto

Almost a full moon interfering with filming, not to mention light pollution but still somehow managed to produce a final image.

IC 5070

19.3.2016 at 01.31 - 03.14 - Tampere
Jouni Raunio, Tampereen Ursa

The night before Saturday was a replica of the previous night: Moon visible, wind, frost and loose clouds. This time the tube was aimed at the shallow constellation Joutsenen, which is more of a shooting scene in the autumn. I should describe this in color then in the fall again. Full size image here .

NGC 2371

18.3.2016 at 20.05 - Oulu (I)
Jaakko Asikainen, Oulun Arktos

Whether it’s great to finally get to shoot, there have been really few weather events this year. I took this planetary, originally named the two NGC objects, found in the center of the constellation of Gemini. The subject is really dim and small, and it didn't help at all that the moon was below 10 degrees from the subject. For more information:

18.3.2016 at 19.50 - 20.50 - Varkaus (IV)
Esa Kärkkäinen

Slightly wider picture. During yesterday's meal trip, the camera rattled for an hour on the beach, shooting in the direction of Orion. Pikkanen meant to be disturbed by the rising moon and light pollution in the city, but some version was born now. There is a bit of a search for widescreen field post-processing. This is an initialization with Pixinsight and a finishing touch with a lightroom.


17.3.2016 at 04.45 - Kauniainen (III)
Olli Arkko, Pollux, Aalto-yliopisto

The last destination of the night is M101. The dimmer parts of this item were already harder to stretch out so the end result may not be as neat as it could be but still clearly the best M101 picture I’ve actually taken. Next time, try some darker place than Espoo.


17.3.2016 at 02.30 - Kauniainen (IV)
Olli Arkko, Pollux, Aalto-yliopisto

One of the three destinations of the night. This was once the first constellation I photographed and I hadn’t photographed again since then so it was nice to get to repeat those beginner’s flaps.

NGC 7822

17.3.2016 at 01.59 - 04.50 - Tampere
Jouni Raunio, Tampereen Ursa

It was a windy evening and night, so I had to shoot from the shelters of the observatory, avoiding the Moon and looking for a suitable direction. The only sensible objects with the equipment in use for the evening would be the nebulae of the Milky Way in the north at an altitude of about 30-40 degrees. Here's one of them. Full size image here .


17.3.2016 at 01.00 - Kauniainen (IV)
Olli Arkko, Pollux, Aalto-yliopisto

As a sunflower gala as one of the three destinations of the evening. Some of the clouds could go from the front in some of the pictures, but in general it is clear the sky even though it was a bit lit by the crescent (and of course there was enough light pollution now).

Matti Helin, Ursa (Länsi-Suomi)

I tried to get the picture as the landscape looked to the naked eye. Imagine; You are in the middle of the forest. The night is at its darkest, the moon is setting. The distance to the car is almost two kilometers, to the nearest inhabited house almost ten. The north wind blows. The owls are rumoring and soon the fox starts a chilling roar. After a while, the lynx's voice echoes in the woods. Some bigger animal is pounding further away. Deer or deer? .. Wolf? I guess no. ..or if it's something, something else .. . The Finnish winter night and swamp are a combination that would have gre...

Exoplanet TrES-3 b

16.3.2016 at 23.46 - 03.02 - Tampere
Jouni Raunio, Tomi Hyvönen, Matti Koskinen, Tampereen Ursa

There was apparently a rush with this observation with the start, or there has been some other inaccuracy in the timing. The fitting routine gave an overflow duration of 75 min. (official estimate 81 min) and a pit depth of 28 mmag (official 27 mmag). Learn more about the place here and here .

Emma Bruus, Ursa (Etelä-Suomi)

I headed to a nearby rapids again to see if I could get a night shot of it without watering the camera. After a few warm melting days, the current was so strong that the rising Frost quickly froze in the lens. Had to finally go home to digest.

NGC 2403

16.3.2016 at 23.00 - Paimio (IV)
Jani Laasanen, Turun Ursa

NGC 2403 is one of the brightest galaxies undetected by Charles Messier. The object was discovered by William Herschel on November 1, 1788. The brightness of this spiral galaxy is about + 8.5 magnitude and the apparent size is about 20 x 10 arc minutes. I photographed the subject at Kevola Observatory in the light of the crescent moon and small clouds occasionally flying in the sky. The galaxy is located about 10 million light-years away and belongs to the same group as the M81 and M82 galaxies. NGC 2403 is remarkably reminiscent in appearance of the third largest member of our own group, the ...

IC 1396

16.3.2016 at 22.43 - 23.51 - Tampere
Jouni Raunio, Tampereen Ursa

For a long time, bright, albeit slightly loose clouds, moonlight and brisk wind. I initially took quick exposures from the “snout” to make sure the equipment that had been dormant for a long time was working. Full size image here .


16.3.2016 at 22.00 - Kirkkonummi (III)
Samuli Vuorinen, Kirkkonummen komeetta

Almost all evening and night was clear, but at times thin clouds passed over Komakallio. Despite the clouds, I recovered a few hours of photons from this galaxy. There is a bright ring around the core of the galaxy, where stars are forming at a rapid pace, and there seems to be another, dimmer ring around the entire galaxy.

Toni Veikkolainen, Keski-Uudenmaan Altair

The Northern Lights did not offer a great spectacle tonight, despite the warnings. However, before leaving home from my standard observation site, I decided to take a picture of the field landscape in the southern parts of Järvenpää in the moonlight. The picture also shows Orion, Hyads and Pleiades nicely. There was only a little frost, but the snowy landscape gave the picture a wintery impression.


15.3.2016 at 21.30 - 01.30 - Mikkeli (III)
Petri Kiukas

As the Milky Way receded from the southern night sky, the M101 windmill gala was chosen as the target instead of the mists. The picture shows my first lights on the subject. 22 x 600s.

Caldwell 14

15.3.2016 at 21.00 - 22.00 - Laukaa (IV)
Pekka Kumpukallio, Jyväskylän Sirius

Finally the equipment starts working, the whole winter has been battled with new equipment and cloudy weather. The moon was starting to be halfway through so I didn’t start trying dimmer targets but took Caldwell as a 14-star star.

NGC 3079

12.3.2016 at 23.05 - Pieksämäki (III)
Timo Kantola, Ursa (Itä-Suomi)

As Catalina sank west into the shadows of the trees, and through the mist clouds the brightest stars were still visible, I found the zenith close-up to be photographed on NGC 3079. 9x7min exposure with 30cmF4 tube and Atik 314L + without filters, revealed the galaxy surprisingly well. The image shows several dozen (?) Distant galaxies as dim, as well as a couple brighter ones, at ten o'clock in the direction of NGC 3073, and for dimmer I couldn't find a name.

There was a clear amount of clear weather last Saturday in the dark, and the weather had to get used to it. Exposure to this Driver's Accumulation accumulated in just over two hours with narrowband filters.

Matti Salo, Keski-Uudenmaan Altair

At the Ursa Club Seminar, both evenings happened to be clear and since I had spent the previous night at Halodek, I decided to wade to the northeast slope of Tähtukallio. There, I sat in a hole in a long snow project and gave the camera a shot. Along with Järkkär, I shot long exposures with an old roll film camera, but sometimes my own observations, if successful.
