Starscape image

30.10.2014 at 22.17 - Lappajärvi (III)
Tommi Ropponen, Ursa (Etelä-Suomi)

After the moon sank below the horizon, a few pictures came from the hotel’s golf course after work, mostly heading west. In this picture, even a slightly unreal green color on the tree trunks is created by the gleaming green light advertisement of the hotel at the back. Unfortunately, the lights of Lake Lappajärvi mess up the bottom of the image in the form of light pollution.

The Milky Way from the archives is described at the end of Porkkalanniemi. The light pollution in the direction of Helsinki was quite intense and in the fleet test images, some satellite came to the best to steal a little unnecessary attention. The air was nice warm and the sea meets calm. I wish there was even less light pollution.

Starry sky image

Tommi Ropponen

Milky Way on a night between Friday and Saturday in Kemiönsaari. Surprisingly, light pollution was also visible here at times, especially on the horizon at both ends of the Milky Way, although according to the light pollution map, the area should be the darkest areas in southern Finland. There are starting to be few dark spots on the south coast this way. Because of the lights, the camera became pointed almost straight up. On the same trip, 8x42 binoculars were tested for the first time, which turned out to be very comfortable, especially considering the price tag of about 100 euros. A 5-year-...

Moon

Tommi Ropponen

The harvest of the rising moon's shooting trip was found in the cache of the archive. The horizon moon could not be photographed as it rose behind the haze layer, but a little later the sky was clear at the foot of Malminkartano Hill.

Several halo forms

Tommi Ropponen, Ursa (Etelä-Suomi)

The spouse spotted the phenomenon outside and would go talk about it. Fast mobile camera images in dng format from the hand. Stack and fast processing without any halo processing skills in Photar. Someone who is knowledgeable could get something out of these, unlike the undersigned. After all, nothing miraculous appears here, but for the signatory, the first observation of this kind. There would probably have been the joy of a decent fisheye here, but there was no such thing available. The first 2 images are a bit distorted in Photar and the last image is an example of a single frame translate...

Partial solar eclipse

10.6.2021 at 14.09 - 14.32 - Espoo (IV)
Tommi Ropponen, Ursa (Etelä-Suomi)

Partial eclipse photographed in Espoo. The vibration of the atmosphere was quite intense in the afternoon, so the quality of the images is not quite what it could have been in the event of an eclipse, for example in the morning. I photographed the hydrogen alpha first from the courtyard of the apartment building (Figures 1, 2, 4, and 5) and then quickly afterwards in white light (Fig. 3). A few different treatments are shown in the pictures. There was a bit of artifact left on the moon disk, but you have to watch if you could handle these files on a rainy day. AR2829 and AR2832 as active regio...

Moon

20.1.2016 at 19.00 - Espoo (III)
Tommi Ropponen, Ursa (Etelä-Suomi)

First light for ASI178MM camera in Leppävaara, Espoo, about 500 m from Ring Road I. Seeing was quite fluttering and the Scene brings its own spices when in a 20 degree frost the houses have quite a lot of heat flowing and the atmosphere is anything but stable. At the time of filming, there was also a thin upper cloud in the sky messing things up. However, the IR-pass filter helped pretty well. The image is stacked with the top 3 percent of 5,487 frames and processed with Photoshop and lightroom. Uncut image. This new ASI178MM seems to prove to be a pretty good tool. Edit: I was still trying to...

Moon

Tommi Ropponen, Ursa (Etelä-Suomi)

In separate images for the period from January to March 2016, a few different lunar phases are depicted. A composite of these combination. According to added another Jupiter from the same period. Mars photographed with different equipment was found in the material a couple of years ago, so I scaled it to the right size and connected it to the picture. Edit: All now also as separate images after the maintenance request. The resolution of the full-size image is 6854 x 3427, so here you can see some details about the moon as well.

Tommi Ropponen, Ursa (Etelä-Suomi)

The sun 31.5. and 5/27/2016 Slightly different image processing and colors as well as composite. The protuts were quite spectacular yesterday and this red section had to be made from yesterday's (May 31) material.

Tommi Ropponen, Ursa (Etelä-Suomi)

Yesterday's roar on the sun's surface. Unfortunately, during the shooting session, the sun was always covered in a thin cloudless cloud, but I wanted to get this gust to recover even if the quality is not the best possible. In the second image, the ground is served on a rough scale (the image is a free-use image from Nassa’s Apollo era, so I dared to add it here).

Testing with Quark and the acronym. Clouds came and went, seeing threw. Not in any way good weather yes except for individual boxes. Here, however, stuff is combined from a couple of squares. Maybe this thing could be summed up so that I don’t mean to get a cloudless sky this summer at all, so that I would sometimes have time to shoot more.

Mosaic practice. There was a thin cloud in the sky all the time, which softened some of the sub-squares of the mosaic. There are not very many spots in the sun at the moment. Better image processors would probably have gotten a couple of gradients out, but I myself gave up on this.

After breakfast, I realized that the sky has been properly clear for a long time. A quick glance at Nasa’s space weather app revealed that really nice protuts are visible on the surface of the sun. Kamat bundle and field. There was a thin cloud in the sky during the shooting, but when I grabbed 5 videos, one seemed to be more successful than the others. However, the seeing was surprisingly good at the moments when the clouds completely disappeared from the sun. The weather was great and especially warm for September. This may be the last sunshine this season. Fortunately, there was publishable...

Tommi Ropponen, Ursa (Etelä-Suomi)

The headlight for the 8 "EdgeHD was finally made on Tuesday (the concept of the headlight will probably have to be stretched a bit when it comes to the tube used, but at least for its own use now.) so here's the ASI178MM right behind the OTA so that the cell should be pretty close to the right distance from the optics. I made two versions of the image: normal and annotated, in which I randomly threw objects and their dimensions into view. The images are native in size, ie about 3000 x 2000 pixels. It would seem that fitting the camera and tube went pretty well on the button, and in good we...

Testing the new Quark when the previous one went under warranty due to uneven image area. The goal was to do tests with all of Quark’s settings to see what comes off the best image. As it was not completely cloudless in Espoo, we sometimes had to wait for the clouds to fade and in the end the battery ran out and the monitoring stand turned off and I didn't have time to go through all the settings. So sometimes you have to keep going. Probably the wisest thing to do would be to stay close to the mains, so there would be no need to leave the field a second time with your neck crooked towards...

The "test runs" continue and the sun is very dull. However, something small can be found on the surface as well as in terms of prototypes. What’s annoying with this warranty-exchanged Quark is that this new protut doesn’t seem to show up properly without their separate exposure. The former was unfortunately a better closet in this respect. I wish I could hope for even a few spots on the surface of the sun now, so that shooting would be more fun. The weather was good, really great, and in addition to the filming, I had to chat with probably ten passers-by and show on screen what a live image of...

There were 2 spots in the sun, so something small is happening after all. At the time of filming, a thin cloud of gauze was constantly sailing past the sun, so transparency was not best. Seeing, on the other hand, seemed reasonable. A few protests visible here and there, but no big flare. Warm enough when shooting, which is nice after the winter frosts. Again, there seemed to be interested enough, so the screen of the laptop became a play on the surface of the sun for a few passers-by.

Tommi Ropponen, Ursa (Etelä-Suomi)

The sun seemed to be a very active area that I tried to describe through thin clouds. In the animation, this is reflected in an unfortunate change in brightness. Seeing was worse than the last time, sometimes the picture was "just a whiff". The animations have 5 frames in each and the animation shows a period of 57 min.

4.6.2017 at 12.20 - 14.33 - Espoo (II)
Tommi Ropponen, Ursa (Etelä-Suomi)

The goal was to have a longer shooting session when the weather was right. I filmed the interval 12:20 - 14:33 until the batteries started to run low on batteries. There was that one spot in the sun, but nothing really happened in that couple of hours. The protut, on the other hand, were quite comfortable. The still image is stacked from a video started at 2:33 pm and features the earth approximately on a scale (the image of the earth is free-to-use images from Nassa’s Apollo era). The animation, on the other hand, consists of the entire time slot and contains 17 separate frames that are loope...

Tommi Ropponen, Ursa (Etelä-Suomi)

Yesterday it was cloudy in Espoo and the filming was not successful, but this morning the weather was cloudless. Seeing was also quite good, which can be seen in the pictures. Shortly before 1 p.m., the weather began to weaken and seeing deteriorated and eventually clouds sailed on. I have made it a habit, whenever possible, to be filming as early as possible, because the weather in the morning and in the morning often seems to be clearly better in the afternoon and evening. The pictures show the active area 2665, which was nice to include in the pictures, even though I went hunting for the pr...
