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...

Mars ja Saturnus

19.3.2016 at 03.40 - Siilinjärvi (III)

Mars, Saturn and some twig in the low southern sky. The brightness of Mars has increased surprisingly much in recent months, a pity that it is so low that there is no talk of meaningful telescope observation. A panorama of a few images when the distance of the planets in the sky was a few minutes of arc too much to fit in the same image with a 180-millimeter lens. According to the picture, Antares had to be got as well, but that old standard filming place is so badly bushed that it is no longer possible from there. It would work for a chainsaw.

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 .

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.

Telescopic comet PANSTARRS

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 .

Mikko Peussa, Ursa (Länsi-Suomi)

I didn't see it myself, so let the picture tell the rest. The directions of the Cassiopeia seemed to come down diagonally. Captured an 8-second exposure at ISO 1600 and does not appear above or after the sequence.

One halo form

19.3.2016 at 00.08 - Turku (I)
Mikko Peussa, Ursa (Länsi-Suomi)

A dim halo in the moonlight exploded into the cartoons of a fireball hunt attempted from the balcony. You could get better from that now, you could make a silky stack with HaloStack and a new bubble blocker :)

Aurora rays

18.3.2016 at 23.45 - 00.30 - Kuortane (II)
Kimmo Kantola, Ursa (Länsi-Suomi)

A few Northern Lights observations had come to the Skywarden during the evening, and I thought about trying to see if it could catch a few more pictures. For half an hour I went for a walk in the neighbor’s fields and no matter how fit a little activity started to show. A moment later, the reposet dimmed to almost invisible.

Atacan Ergin

Bz negative, skies clear, so I went to take some shots. It was windy, so I couldn't stay long. It's cool to zoom in to see details, when the aurora is not strong enough to get a wide shot of an arc.

Experiment. Olympus zc 2 compact camera + lens telescope Unitron 102-1500 mm. The camera has a fairly large lens lens, so suddenly the edges of the eyepiece are photographed. Therefore 40 mm. eyepiece so that there is no need to photograph the edges of the eyepiece. Pictured is the Copernicus Crater. #Lunar100: 005

Auroras seen through breaks in the clouds

18.3.2016 at 23.15 - Muonio (II)
Heikki Ketola

Northern lights on Pallastunturi as seen from the Salary Box. A growing convex moon would illuminate the fells as part of the shadow of the clouds. Later, the northern lights activated over the sky cover into blazing arcs and at times flared riotously in the northern sky as well. It was bright at midnight in the fell.

Kirsi Volanen

Last year there were really great northern lights for these times. The most amazing I've seen. Now these northern lights were pretty dim tonight. A moment earlier there were rays and brighter firing, but I didn’t have time to dry them when I pulled on the warmer clothes and picked up the camera. Then I went to the shore of the lamp and a little bit of this streak in that north direction intensified, but I couldn't stand it either. Well, I didn't need to take a long time in the cold.

Quiet aurora arc

18.3.2016 at 23.10 - Utajärvi (II)
Eero Halme

I photographed the arc of northern lights and only noticed the fireball while looking at the image on the computer screen. Neither this observation nor the image goes through. I only saw the fireball in the picture when I had photographed the arc of northern lights and looked at the picture on the plane.

Antti Rinne, Ursa (Länsi-Suomi)

Throughout the evening, I had found the northern sky suspiciously pale. Just for fun, I went out with the camera after ten, that if there were northern lights. When I got to the scene and got the camera ready, the northern lights came on as if by order. Sometimes I did. However, they then coagulated almost as fast as they started, especially when there was a bit of poor visibility from the observation site to the lower northern horizon.

Mikko Peussa, Ursa (Länsi-Suomi)

My camera shot a series of possible fireballs on the balcony. At. At 22.34 images, repos appeared in the north. Also visible to the eye, even though it was dim. I saw in the south when we are observers of such a northern Finland, be careful :) Bad dock photos coming into view today :) EDIT: I promised bad documentaries. Here's one, please. So the view is from a fireball hunt, which will not but produce that result at all :)

It was a clear evening in Tampere and this is how the moon appeared beautifully at the Ursa observatory in Tampere, Kauppi. Here is a drawn lunar crater Bullialdus as well as nearby smaller craters. In the first picture, the colors of gray are close to the real colors of gray. In another "false color image", the bright parts of the craters close to the true brightness of the object observed with the eye. The third image is a softened background

Another attempt to describe the telescope with Jupiter. Surprisingly well, the surface details can be seen with about a small tube. Stack of 150 squares.

Jupiter, Europa and Io in gusts of wind, but seeing just moderate at times. The tube of the association is on an azimuthal pedestal, but the planetary image seems to do just fine.

Niko Hokkanen, Ursa (Länsi-Suomi)

It was clear and the moon was high, so I decided to shoot it at a slightly higher magnification. The surface of the moon vibrated quite a lot in the telescope, but stacking the video still gave a relatively successful picture. Admittedly not very accurate because there was too much magnification.

Heidi Rikala, Ursa (Helsinki)

Northern lights for a change. The delicate greenery was already visible at 21.58, but deliveries began in 22.42 countries. These were not very strange, but the feeling was that now let’s take it all out of them. It was a challenge when the repos showed up for a while and then it was quiet. I waited persistently and yes they came back again. This alternation then continued. The play started just fine with bright and active fires, but then they didn't get any better. The arch was very low at the time of the gathering. The supply was very good, I got along well in the field without sinking. T...

Copernicus stumbled close to the terminator as if inviting the scenery to look at the "vista tongue" on its edge. Hopefully one day we will see a picture taken on the spot, even though the Moon seems to curve so sharply as a small sphere that the opposite edge can't be seen? At least I remember that an observer standing in the middle of the crater would not see the crater ramparts because they are left behind the horizon.

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:

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.

I had already thrown this away because the video was so shaky due to the high magnification and manual tracking. I removed the bad boxes and got some sort of picture.
