M99

30.3.2023 at 22.50 - 22.35 - Janakkala, Tervakoski (III)
Petri Kuossari, Riihimäen tähtit. yhdistys

The night went by three tubes, exoplanet observation with eVscope, Messier objects with Vesper and testing with Dwarf II tube. The northern lights were also in the sky for about 20 minutes saying hello. In this picture, M99 captured on Vespera.

Markarian's Chain (M84, M86, M87)

Petri Kuossari, Riihimäen tähtit. yhdistys

It was a bit too much adjustment for the evening at once. I watched the rocket launch at about 22:30 onwards, while the Vespera tube imaged the M86 mosaic, eVscope had two supernova alerts lined up, at At 23:00 the second supernova recording ended and I started a new one over a minute at 23, I checked again that the trees do not come in front of the observation and at the same time with the side eye if the rocket launch can still be seen, then I thought I would have time to send the report to the Seti Institute on the computer inside and quickly go back outside to see if the rocket could be se...

Markarian's Chain

27.3.2023 at 23.10 - Kuusamo
Voitto Pitkanen, Ursa (Pohjois-Suomi)

This shooting destination of mine is traditionally one of the last of the season. Shots with a 600mm combination. The crescent moon lit up the landscape quite a bit, but the glow of the aurora borealis was gone. In total, 25 min of exposure (1-1.5 min/time) and 15 shots.

M78

22.3.2023 at 21.00 - 23.30 - Kuopio (I)
Jussi Koponen

I have described this beautiful reflection fog several times, the subject is really challenging, the trees and the Moon have interfered with several partial exposures and many have had to throw frames in the trash. Exposure time about 8 hours. bigger picture on my website: https://astro.galleria.fi/kuvat/2014 Deepsky/M78_full.jpg

NGC 7023

21.3.2023 at 22.50 - 03.39 - Rautalampi (II)
Vesa Vauhkonen, Sisä-Savon Ursa

Someone has swept some of the dust from space around the Iris Nebula. A bit tricky to shoot with an osc camera and a light pollution filter. Light exposures for 4.25 hours. EDIT: Added version with calibrated star colors.

IC 2118

20.3.2023 at 22.12 - 23.59 - Kuopio (I)
Jussi Koponen

From my location, I photographed this gas nebula, nicknamed the "Witch's Head", located very low in the southern sky. The tops of the tree came very quickly and the exposure time was a troublesome few hours. The focal length of the imaging tube was 600mm. The picture can be found in a larger size on my website: https://astro.galleria.fi/kuvat/2014+Deepsky/NoidanpääSumu.jpg

Topias Tanhuala, Ursa (Länsi-Suomi)

A rare clear night, so I decided to take pictures with my phone. The street lights turn off at midnight and I got a nice foreground from the street light. I was able to see the stars surprisingly well. The Lyra constellation is nicely visible in the picture and the bright star of the picture is Vega

The quiet night of the moon, silence and peace. Exoplanet observation going on in the northern sky. This is the everyday life of a star enthusiast.

Coman galaxy cluster

16.3.2023 at 23.49 - 04.17 - Virolahti (IV)
Tero Hiekkalinna, Ursa (Helsinki)

The object of the second night of the Virolahti star tour was the Coma galaxy cluster, whose central region is located approx. 321 million light years from Earth. The cluster includes more than 1000 galaxies. Exposure in the picture is 3 hours and 50 minutes.

NGC 5473

16.3.2023 at 23.30 - Ulvila, Kullaa (III)
Juha Ojanperä, Porin Karhunvartijat

NGC 5473 is a lenticular galaxy in the constellation Ursa Major. The galaxy was discovered by William Herschel on April 14, 1789. The galaxy is part of a small group of galaxies, the other members of which are NGC 5475 and 5485. Visually, the galaxy appeared as a small, round hazy patch, with some kind of central brightness standing out in the middle. The visual size of the galaxy is about 1' x 2'. #Herschel 400

NGC 4051

16.3.2023 at 23.10 - Ulvila, Kullaa (III)
Juha Ojanperä, Porin Karhunvartijat

NGC 4051 is an intermediate spiral galaxy in the Ursa Major. The galaxy has features of both a regular and a bar spiral galaxy. The galaxy was discovered by William Herschel on February 6, 1788. Visually, the galaxy appeared as a roughly 5' x 2' oblong hazy and dim patch. The long axis of the galaxy is roughly northwest-southeast. An almost star-like central glow can be seen in the middle of the galaxy. #Herschel 400

M31

16.3.2023 at 21.35 - 23.27 - Jyväskylä (IV)
Juuso Ratilainen

16.3.2023 On Thursday, there was a cloudless and moonless sky. I went for the first time to try to photograph the Andromeda galaxy. The photo was taken in Jyväskylä from Tuomiojärvi near Haukkalanranta.

16.3.2023 at 20.10 - Kuopio (IV)

The birch and the star (Sirius) were so nice in the hall that I had to take a picture of it when the Swedish barium rocket launch had now been cancelled. Despite the short exposure times (1.6 s), Flame Mist and Rose Mist stand out.

IC342

16.3.2023 at 00.12 - 00.50 - Janakkala, Tervakoski (II)
Petri Kuossari, Riihimäen tähtit. yhdistys

As the northern lights blazed, I photographed the "hidden galaxy" for 39 minutes. The features are shown surprisingly well with such a short exposure.

NGC 7129

15.3.2023 at 23.32 - 00.03 - Janakkala, Tervakoski (III)
Petri Kuossari, Riihimäen tähtit. yhdistys

The aurora lights light up nicely at the same time that I was shooting an exoplanet with a science tube and Vespera was shooting the cosmic rose nebula.

Markarian's Chain (M84, M86, M87)

15.3.2023 at 23.23 - 04.30 - Virolahti (IV)
Tero Hiekkalinna

We went on a traditional star tour in Virolahti to photograph spring galaxies and on the first evening the target was the Markarian's Chain galaxies.

M64

15.3.2023 at 21.00 - Paimio (IV)
Eeva-Kaisa Ahlamo, Turun Ursa

The bad ass of the galaxies, M64, or the Black-Eyed Galaxy, has carved out quite a lot of space for itself in the otherwise galaxy-filled constellation of Berenice's hair. The other galaxies wisely stay further away from the challenger's vicinity. William Herschel described the galaxy M64 in his notes in February 1787 as follows: "...it has a bright spot, like a star, with a small black arc below it, thus reminding one of the so-called black eye, born of a fight." (At that time, galaxies were not understood as galaxies, but as "nebulas".)

M3

12.3.2023 at 23.41 - 01.53 - Rautalampi (II)
Vesa Vauhkonen, Sisä-Savon Ursa

Ball M3 with a short (550 mm) focal length. With a longer tube, the stars in the middle area would appear more separate, of course. An interesting experiment, though.

NGC 1499

12.3.2023 at 22.00 - 23.35 - Janakkala, Tervakoski (III)
Petri Kuossari, Riihimäen tähtit. yhdistys

Vespera captured this California nebula while eVscope was passing Kepler-170b, part of NASA's UNITE project. This is a functional combination (Vespera / eVscope) when you can take advantage of the fun and benefit at the same time. Adjusted the tones of the second and third image.

Coman-Virgon galaxy cluster

12.3.2023 at 21.15 - Paimio (III)
Eeva-Kaisa Ahlamo, Turun Ursa

In March, the race against spring begins, you try to use all moonless, clear evenings to your advantage by looking at the sky. I went to Kevola to see if any galaxies would catch the observation network. And I caught them full of the camera (or in this case the 80/600mm Skywatcher). I have never stacked pictures, so learning (and motivation to learn) is still needed. For the first tests, however, it was quite fun, I marked (I think) the galaxies shown in the picture for the latter. It was nice that M87 could also fit into the picture with a rather blind shot. (You can only see the M86 / M84 on...

Jussi Koponen

I found an old Samyang 85mm f1.4 manual lens in the sock drawer, which I then pointed in the direction of Kassiopeia. The image field of the lens is so large that two star nebulae and a spectacular double star cluster could fit in the same frame.

Petri Kuossari, Riihimäen tähtit. yhdistys

I took the previous photo of the Witch's Head Nebula and Thor's helmet was nearby, so here is a short exposure of NGC 2359. It is difficult to get a good picture of this object. Waiting for the perfect Seeing air with the name tag.

Vesa Vauhkonen, Sisä-Savon Ursa

Hidden Galaxy as a filming location. It is large and bright in itself, but is so close to the level of the Milky Way that interstellar dust 'hides' it. Actually an autumn destination. Quite high also in the north.

Tommi Ropponen, Ursa (Etelä-Suomi)

I went to shoot at the southern tip of Porkkala in quite a wind and praised the good decisions: Extra weights to support the tripod & a hot drink in the thermos. Several horned creatures could be seen in the nearby terrain of the beach cliffs, and when we came back, there were two gentlemen by the fire at the Merikotka campfire site. The place can be found when you first drive to the address Tullandintie 184 Kirkkonummi and walk from there for about 1.4 - 1.5 km. behind my back. This very southern point of the cape is probably the darkest place that can be found in the vicinity of the pk regio...

I wouldn't have put this picture here otherwise, but for people who are interested in the DWARF II tube. This photo was taken with a tube weighing only 1.2 kilograms. And this pipe is not expensive. Maybe this works better for nature photography, can track flying birds automatically, can also take video or even a billion pixel landscape photo. The software still seems to be Unfinished.

NGC 3938 is a Sc type spiral galaxy located in the Ursa Major constellation discovered by William Herschel on February 6, 1788. The spiral galaxy is located in such a position that we look at it directly from above. The galaxy appeared visually as a dim and hazy, round patch. It is difficult to find out about its exact shape and position. The galaxy would appear to be slightly elongated, the long axis would appear to be in the southeast-southwest position. In the middle of the galaxy, a faint central brightness stood out. The visual size of the galaxy is approximately 4' x 3'. #Hersche...

Marko Haapala

As a child, you had to stare at the earth and the starry sky on the tin roof, then at the current location you could see a little more of them, even in winter. 30 years ago, the first camera was used to zoom towards the shape of Orion's hourglass, and there that reddish dot was visible as a blur and a little wider than the stars next to it. Time passed and slowly we got a little closer to the target, but the result was miserable and noisy and a disappointed photographer. Still, that time passed and the photographer also had time to develop during that time, in addition to everything else. ...

In the evening I was going to a party, so I programmed Vespera to automatically start at 19:00 and start. The third target at: 21:00 was M95 with an hour exposure, M96 came on the market. The robot tube took care of the job while the host was at the party. Apparently, there has been light cloud at this point, when you look at the picture. Vespera took only 269 pictures, shooting time 44 minutes. I could conclude that it was cloudy for about 15 minutes, but I don't know since I wasn't there myself.

Very rarely has there been an opportunity to practice using the tracking stand. Yesterday the sky was clear, so I braved the wind and the frost and went to try what would come. Orion was handsome in the sky. The wind was freezing, the camera was shaking and swaying. Polar aiming succeeded so well that with the 200 mm lens it was difficult to take one-minute exposures. I took 8 pictures of the fog, 4 of which I passed for further processing. I stacked and processed the images in Photoshop. The pictures are cropped quite a bit. The end result was a positive surprise, how much details and colors ...

Mehr Licht! More light! According to the story, the last words of Johan Wolfgang von Goethe. And the first words of the signer when I looked at the first version of Horse Horse Fog after DSS processing. Even after image processing, this iconic (i-koni?) object remained a bit anemic. Forty 30s exposures, or only twenty minutes in total, but when the opportunity comes, more exposures must be made and added to the previous ones. This is easy to find. The bright star in the middle is Alnitak, the leftmost star in Orion's belt, m = 1.9. The north is down; I left it in this position because I th...

The legendary Triangle galaxy was once again the subject of an exposure series with Alluna, but this time I tried the triple rather than double binning that is typically used with it. There didn't seem to be anything interesting on the edges either, so I cut them off.

An old familiar destination. I photographed the fog with a 135 mm lens, so it fit in its entirety in the frame. Still have to try separating the Ha-OIII channels and combining the images. Would the colors of hydrogen and oxygen come out better.

I didn't see the zodiac light, but then I photographed the starry sky from a nice observation point. I turned my attention to Sirius' active twinkling. I decided to photograph the twinkling from a tripod by "sweeping" from field to field with a long exposure and a long tube slightly out of focus.

Starry sky in the direction of Orion, 8 exposures of different lengths (10s-22s) stacked on Sequator. The effect of light pollution (orange background sky) was reduced by adjusting the color tones in a more bluish direction in Photoshop.

After a long time, a couple of consecutive clear moonless evenings on February 10-11. The Rosette Nebula has been at the top of the target list for a long time, and now its filming finally took place. Small challenges appeared during the shooting when I noticed that the target is not exactly in the middle of the image field. For some reason, I didn't notice this on Friday night, and Saturday I had to go with the same alignment so that I can combine the stars and fog from consecutive nights in the post-processing without any problems.

I photographed starry sky time lapse again on Tähtikallio during the solar system meeting on the night between Saturday and Sunday, i.e. 11/12/2/2023. Unfortunately, I only found out afterwards that the white balance setting was wrong, and the whole set of pictures (about 700 pictures over a period of 6 hours) had the wrong white balance setting. I use GIMP as an image processing program, and I have not yet found the possibility to process a large number of images at once, I should be able to process all 700 images with a certain script, in which case I would be able to adjust the white balanc...

Spaghetti fog, a very challenging object due to its vast area and weak surface brightness. Getting the Samyang 135mm/2 lens on board with the rest of the equipment required a bit of improvisation. On the INPUT side, the filter is L-Ultimate, with step-down adapters. Added some vignetting and asymmetric flare of stars in the peripheral areas. An interesting experiment, though. Light only 12 x 15 min light, 12 x 15 min dark.

While I was photographing the comet with two tubes, I thought I would test the phone's hyperlapse feature. I put the phone on the stand and took a moment to take a picture, and of course the phone rang and the alarm vibrated (shown at the beginning of the picture). The rising of the moon can be seen well when the trees light up, the colors of the stars also stand out perfectly, especially Orion's Betelgeuse clearly draws a redder line. Here's a 50-minute exposure. Definitely have to try the same in a longer time.

After photographing Comet C/2022 E3 (ZTF), I decided to try photographing the Andromeda galaxy with camera optics. Due to the lack of a follower platform, I had to leave the exposures quite short (10 seconds), and all in all, the exposure accumulated for only a couple of minutes (12*10s). Stacking with Sequator. During the final processing of the image, I ended up changing the image to black and white, which made processing a little easier. M31 and M110 standing out as a fog spot on the right side of its nucleus.

Again, try to hold on. The intention was to photograph the comet, but those clouds... It became clear later. I chose a safe target. I only got light for 27 x 1 min, then it got cloudy again. I tried to bring out the surrounding 'fringes', but it was a bit dull. Too little data.

The weather report promised maybe half an hour or at most one hour of clear skies in the evening, so the pipe line to cool down. I started around 19:00 and finally the evening stretched into the morning. There were bigger changes to the plans because I wasn't prepared for the observations of the whole night. Fortunately, the weather report can sometimes also be positive. The main target was the clear comet C/2022 E3, both scientific observations and pictures for your own pleasure. I also noticed a couple of transits of asteroids during the night. More about them after the analyzes are comp...

I saw a nice version of this iconic object in the starry sky online that used a rarer image palette. I decided to try my own version with a remote telescope. Well, this turned out to be a bit of a stub version with a total exposure time of 'only' 10 hours, but I'm quite satisfied with this and especially since I was able to remove the disturbing stars.

While waiting for Uranus to be covered, a few pictures of the Orion Nebula were taken with a 600mm lens. I had recently downloaded Siril and thought I'd try how it would handle star images. Well, no way. It boiled down to the fact that I didn't have the darks, flats, etc. that Sirili's automation needed, and I didn't know how to proceed with just "lights". But the exposures were not completely wasted when I stacked six images with HaloStack as an average stack. You shouldn't make big prints of that, but you can recognize the object :)
