Active aurora band

15.1.2022 at 22.00 - 00.00 - Järvenpää (III)
Eemil Pietilä, Ursa (Etelä-Suomi)

I missed the northern lights the night before, so I decided to put the gopro on duty the next night. Well, it was worth it. When I checked the camera from time to time, I also saw the first northern lights of my life with the naked eye. After the video, there are a couple of pictures of what I think are the best parts of the video.

Starry sky image

10.1.2022 at 21.00 - 23.00 - Järvenpää (III)
Eemil Pietilä, Ursa (Etelä-Suomi)

The intention was to photograph the constellation of Orion from the front for 4 hours, but due to the cold frost of about 20 degrees, the batteries froze faster than I expected. The end result was 2 hours of data. Well luckily I shot in a narrowband so I got to see a little more detail. The intention would be to describe a little more narrowband and then RGB. These could then be made into a nice combination.

NGC 1499

Eemil Pietilä, Ursa (Etelä-Suomi)

The evening looked clear, so I decided to try the new Optolong L-eNhance multi-narrowband filter. The California fog seemed to be an easy destination to start with due to its relatively easy discoverability. Even though there is only about an hour and a half of exposure here, of which about 5 minutes is RGB, I got surprisingly good detail. Actually, the efficiency of the whole filter surprised me. I got more detail in the middle of town on a bortle scale in maybe 7 or 8 and a half hours than I did before shooting this subject in RGB in three hours. Unfortunately, that RGB data last time suffer...

Moon

21.12.2021 at 21.00 - 21.15 - Järvenpää (IV)
Eemil Pietilä, Ursa (Etelä-Suomi)

Although I photographed the moon itself for a maximum of a quarter, it took me at least an hour more to assemble and unload the equipment. Yes, my fingers pretty much froze when I had to take my gloves off in order to get a better grip. Fortunately, it was worth it. About 150 images of the Moon have been stacked here and the image has been sharpened slightly. At first, I had to calibrate the colors to get off the red hue caused by the modified camera. After that, I raised the saturation to bring out the colors of the Moon’s minerals. Finally, adjusting the basic contrast and brightness was no ...

M42

7.12.2021 at 23.00 - 02.00 - Järvenpää (IV)
Eemil Pietilä, Ursa (Etelä-Suomi)

Orion gas mist with approx. 3 hours exposure. This time I tried to edit the image in Pixinsight when I used to use Photoshop alone. The first experiment, at least in my opinion, was relatively good. Somehow I brought out more of that faint fog and the colors look kind of more dynamic too.

Binocular comet Leonard

Eemil Pietilä, Ursa (Etelä-Suomi)

I’m still trying to figure out how to get the images from the comet stacked, because at least DeepSkyStacker’s comet mode didn’t work. However, I managed to make a short comet with a data time of about 45 minutes about the comet. I first processed the images using Camera Raw, then uploaded them to Photoshop as a series of images. After that, I adjusted the aspect ratio to the right and exported it as mp4 video. The fact that you can process videos in Photoshop became a new thing for me. I’ve always thought it was just for pictures.

M45 and NGC 1499

26.11.2021 at 22.30 - 02.00 - Järvenpää (III)
Eemil Pietilä, Ursa (Etelä-Suomi)

I photographed this target pair through a 50mm lens. At first I was skeptical about the weather, but after 10pm the weather became clearer and I decided to put the camera to shoot. After a while, I realized that the camera battery was exhausted, so I replaced it with a new one. But it didn’t take long for me to come back again and this time the power bank battery was running low, so I went looking for a new one and found one. In order not to solve it with such small problems now, the fuses on the cake burned over the whole house, which meant that the laptop no longer received power outside and...

M31

18.11.2021 at 19.00 - 20.30 - Järvenpää (IV)
Eemil Pietilä, Ursa (Etelä-Suomi)

The weather became clear for a moment, so I decided to add a little more exposure to my Andromeda picture. Now the total exposure is about 4.5 hours. The details came out nicely. I also decided this time to edit more natural colors. A nice addition was the removal of the stars with Statnet ++ so that I could handle them separately and thus managed to remove the halos more efficiently.

M42

13.11.2021 at 00.00 - 02.00 - Järvenpää (IV)
Eemil Pietilä, Ursa (Etelä-Suomi)

Orion's Nebula ST80 through my telescope. I removed the stars with a software called Starnet ++ to get the halos removed more efficiently. I did well, at least in my opinion. I will put a link to my previous observation so you can compare. https://www.taivaanvahti.fi/observations/show/101869

M31

8.11.2021 at 23.00 - Järvenpää (IV)
Eemil Pietilä, Ursa (Etelä-Suomi)

I was lazy and couldn’t go out into the field to shoot, so I decided to photograph the Andromeda Galaxy from my backyard. Now that I was in my own backyard and got power with an extension cord, I also decided to use a laptop that rotates on my laptop for the first time. Personally, I was inside in the warmth when the camera snapped pictures outside. I also stacked the Andromeda pictures I took in October, so the total exposure was 4 hours.

NGC 6888

6.11.2021 at 23.00 - 00.00 - Järvenpää (III)
Eemil Pietilä, Ursa (Etelä-Suomi)

The intention was to photograph the sickle fog, but filming was suddenly interrupted by an increase in cloud cover. Later in the night it became clear again, but that’s when I changed destinations.

M45

1.11.2021 at 21.00 - 23.00 - Sipoo (IV)
Eemil Pietilä, Ursa (Etelä-Suomi)

I photographed Seulas from Sipoonranta. There was a little light pollution in the east, so I got a lot of visibility even with about 2 hours of exposure. Finally, I photographed another landscape of the beach.

M51

17.10.2021 at 22.00 - 01.00 - Järvenpää (III)
Eemil Pietilä, Ursa (Etelä-Suomi)

Described as a vortex shutter with about 3 hours of exposure with the full moon in the sky. Surprisingly, the galaxy appeared. It was good that there weren’t a lot of bright stars around the galaxy, so the halos created by the achromatic telescope didn’t bother me.

Moon

17.10.2021 at 21.00 - 21.15 - Järvenpää (IV)
Eemil Pietilä, Ursa (Etelä-Suomi)

Shooting the moon while introducing a friend to a star hobby. In total, such light 6 hours were spent in the field.

M42

17.10.2021 at 03.00 - 04.00 - Järvenpää (IV)
Eemil Pietilä, Ursa (Etelä-Suomi)

When I left the rain at midnight, I wondered if it would be worthwhile to start shooting again later. Well, it was worth it. I went to grab a quick about an hour of exposed Orion nebula. Yes, note that there is little skill and equipment improved since last winter. Below is a link to last winter's observation. https://www.taivaanvahti.fi/observations/show/95632

Starry sky image

13.10.2021 at 22.00 - 00.00 - Järvenpää (III)
Eemil Pietilä, Ursa (Etelä-Suomi)

The constellation of Swan and the Sadr region there, as well as the fog of North America, photographed with about 2 hours of exposure in the middle of the city. The purpose was to test a 50 mm lens found in stock for star photography. It seemed to work relatively well. The details now didn’t come out so closely, but the overall picture is pretty jees. At the same time, a self-made heater also became tested to work. And, of course, I didn’t notice taking a picture of that tuning.

M31

3.10.2021 at 00.30 - 02.00 - Järvenpää (IV)
Eemil Pietilä, Ursa (Etelä-Suomi)

Once, when there were good conditions to photograph, of course I forgot to charge the travel charger, which uses the frost and moisture barrier. As a result (surprise surprise), the telescope lens misted when the battery ran out. Well, that battery lasted an hour and a half, so here’s the Andromeda galaxy with a total exposure of an hour and a half. Given the circumstances, the image did come as a surprise, although more exposure would have been better.

NGC 6992

27.9.2021 at 00.30 - 03.00 - Kokemäki (III)
Eemil Pietilä, Ursa (Etelä-Suomi)

At the cottage away from light pollution, it is good to try the new modified EOS 1200D. Only the light of the moon disturbed me a little, but yes there was still something in the pictures. Here is the Eastern Gauze Fog with a total exposure of 2h30min. I took 30 second exposures that I stacked with a Sequator. I also tried the new Photoshop action Pack, which dims and reduces the stars. I made the finishes in Lightroom.

Sun

19.9.2021 at 14.30 - 15.00 - Järvenpää (III)
Eemil Pietilä, Ursa (Etelä-Suomi)

Although there has been cloudy weather now, at least here in southern Finland, it became clear today for about an hour. So I decided to try the new full Spectrum modulated Canon EOS 1200D to capture the sun. The results were satisfactory, as the focus seemed to be a bit wrong, but the pictures were still ok. At the bottom left, you can see the dim sunspot group 2871.
