NGC 7000

8.8.2022 at 00.30 - 02.30 - Järvenpää (IV)
Eemil Pietilä, Ursa (Etelä-Suomi)

The first picture of the 2022-2023 season. The picture shows approx. 1.5 hours of narrowband data taken from my own backyard. I had to throw some of the pictures away, because around 1 o'clock in the night, a thin layer of clouds appeared in the sky, which disappeared completely by 2 o'clock. Considering that my backyard is bortle 6-7 levels and the lack of data obtained, I am surprisingly satisfied with the end result. At the same time, I got to test my new Sky-Wathcer EQM-35 Pro tripod. You should still try to connect the tripod to the laptop so that dithering and camera control woul...

Moon

13.6.2022 at 22.15 - 23.00 - Espoo (IV)
Eemil Pietilä, Ursa (Etelä-Suomi)

I had been watching the moon for a few days while I was in Espoo. Then, as I figured out the exact time and location of the moon to rise, I noticed that right next to my accommodation near Klobben beach, you would see perfectly when the moon rises. I left for Klobben on Monday night so I arrived just before ten. At first, nothing was visible, but at about 15 more than ten moons began to peek behind the shadow of the earth. No more when the camera visits and takes pictures. Eventually I ended up shooting the moon for about 45 minutes. I also tried timelapse, but unfortunately it didn’t quite wo...

Sun

20.4.2022 at 16.00 - 16.15 - Järvenpää (III)
Eemil Pietilä, Ursa (Etelä-Suomi)

I did a fun test where I tested whether Optolong l-enhance helps to describe the hydrogen alpha structure of the sun at all. Well, it didn't help, which wasn't a big surprise right now when it comes to the filter for capturing the deep sky. Anyway, I got to photograph the stunning comma groups on the surface of the sun right now. Actually, I’m surprised at how well those dots came out. It was also nice to observe the spots through the telescope with your own eyes.

Starry sky image

5.4.2022 at 22.00 - 22.45 - Järvenpää (IV)
Eemil Pietilä, Ursa (Etelä-Suomi)

At the very beginning of April, I got a couple more hours of more exposure from the constellation Orion. In addition, I used old data from last winter. Now I had time to edit the picture from my school rushes and yes that fog came out surprisingly well. Actually, the results of those nights in early April were the most surprising. I didn’t expect them to bring much more to the picture anymore. In total, there is now 2.5 hours of narrowband data and about 4 hours of broadband.

Caldwell 49

20.3.2022 at 21.30 - 22.30 - Järvenpää (III)
Eemil Pietilä, Ursa (Etelä-Suomi)

The intention was to get more exposure for this, but the cloudy weather surprised. Soon the subject would have moved behind the trees anyway. Will have to try this destination again next winter. The balance of last winter was about an hour of exposure.

Moon

16.3.2022 at 17.30 - Järvenpää (III)
Eemil Pietilä, Ursa (Etelä-Suomi)

I decided to try Samyang’s 135mm lens during the day as well and thought such a hot landscape would be a good test subject. Not when but a camera and a tripod in a backpack and a bike to the lake. I arrived just in time when the sun was setting behind the trees, but still illuminating the forest. The moon was already suitably bright.

Milky way

13.3.2022 at 03.00 - 04.00 - Järvenpää (IV)
Eemil Pietilä, Ursa (Etelä-Suomi)

In the fall, there was little filming of the Milky Way, so I decided to correct the injustice and now take pictures of it this weekend. Yes, I can say that this was much better than last autumn. Editing skills have thus developed greatly.

M81 and M82

22.2.2022 at 22.30 - 01.45 - Järvenpää (II)
Eemil Pietilä, Ursa (Etelä-Suomi)

The first attempt to describe the Bode Galaxy and the Cigar Galaxy in the "galaxy era" now beginning. I am now trying to get more exposure for this subject during the new moon so that I can possibly display IFN in the area. At least 10 hours would be the goal to get. There are only three hours of exposure in this version, so IFN was not yet visible.

Caldwell 49 and NGC 2264

20.2.2022 at 20.00 - 20.15 - Espoo (III)
Eemil Pietilä, Ursa (Etelä-Suomi)

It was supposed to be clear over the weekend, but two nights just after I got the camera to shoot, it got completely cloudy. In the end, this is all that was left in the hand over the weekend. A total of about 10 minutes from the exposed Rosette Nebula, the Christmas Tree Cluster, and the Cone Nebula. I shot in a narrowband and combined the colors in the HOO palette.

Moon

12.2.2022 at 16.45 - 17.15 - Järvenpää (IV)
Eemil Pietilä, Ursa (Etelä-Suomi)

I didn’t get to shoot on Friday night, but luckily now on Saturday there was a small piece of clear weather that allowed me to get a well-photographed moon. Pikkanen became in a hurry when, on a bike ride more than 10 kilometers from home, I realized the sky was clearing. Well not when the cam towards the home and immediately at home shooting equipment ready. The Orion ST80 was used again for a long time.

M42, Barnard 33, NGC 2024

24.1.2022 at 21.30 - 23.30 - Järvenpää (IV)
Eemil Pietilä, Ursa (Etelä-Suomi)

A combination of narrowband and broadband from the constellation Orion. Both are about 2 hours away, so not much of the area's reflection fog is yet visible here, but the goal would be to shoot even more broadband for this subject. However, with only about 4 hours of total exposure from a relatively light-polluting place, I can be happy with that. I added to the end the pictures I had drawn of this picture of Orion's fog and Horse's head fog. Surprisingly, there is enough accuracy in this Samyang lens.

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

1.1.2022 at 21.30 - 23.00 - Järvenpää (IV)
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

5.12.2021 at 05.30 - 06.15 - Järvenpää (II)
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
