Vastapilvisäteet

9.9.2018 at 19.05 - 19.25 - Mustasaari (III)

A thunderstorm cloud passed from the west of Vaasa created counter-cloud rays. The first things I've noticed. 7 image panorama. The rays extended from the sun over the sky to the opposite horizon.

Total lunar eclipse

31.1.2018 at 16.55 - 17.00 - Vaasa
Tommi Järvilehto, Vaasan Andromeda

It was at the right time that an opening went to the moon in the cloud. At first it seemed at first nothing was visible, but the slowly eastward opening in the cloud promised at least some kind of vision of the moon. The shadow was surprisingly strong compared to the partial lunar eclipses I had seen before. The moon seems to be so dim on the horizon.

The moon finally came out after the total eclipse. Picture of the loading tower of the mills in the inner harbor of Vaasa. Today used by the Swedish-speaking student union. Music festivals were in the harbor at the same time.

Nice to watch the complete lunar eclipse from your private balcony while enjoying your morning tea. The moon was so high that it was well visible. It was cold, -15C. During the deepest phase, the sky was closed. At first it was clear. Towards the end, the cloud ferries also went before the moon. During the cloud, the battery also ran out. Missing images from cloudy weather. Still picture taken at about 07:44

This interesting, steadily flashing space debris object was followed at the Meteoriih Observatory appropriately during the public display. Really bright about 0 mag flash at about 5-10s intervals. I couldn't find anything that could be this. It was nice to see Panu's observation of the same object in Taivaanvahti: https://www.taivaanvahti.fi/observations/show/44431 Picture 1 16x30s stack Figure 2 partial exposure at 20:35 Figure 3 Partial exposure at 8:38 p.m. Figure 4 partial exposure at 20:39 Time accuracy approx. + / - 1.5min Heavens Above: http://www.heavens-above.com/passdetails.a...

Sunset rays

During the day there were promising forecasts for the coming thunderstorm. The bonga trip became a sleeve, but at sunset the gray evening skyline turned into a beautiful orange. The sun shone from the horizon.

Nice relatively warm star photography for a long time with the association's 60mm Lunt. A spectacular sunspot comes from behind the sun. Earth added to another 100% cropp for comparison. The diameter of the sun is 1660 pixels and the diameter of the earth is 15 pixels

The sun of the day and its speck. The comma is now heart-shaped. The heart of five planets :) The CCD camera, on the other hand, is bullied with the wrong subjects, but nowhere else is it in use. The full picture is a stack of 16 pictures out of 62. Pretty much got thrown away as the atmosphere rippled. There was also a late shooting time. In the comma image, a stack of 18 images out of 60. I included black and white photos now, in addition to false colors.

The sun of the day. Today's image did not have the same sharpness as yesterday's. http://www.taivaanvahti.fi/observations/show/51428 The comma has moved. There should be more weather tomorrow. Let's look and practice again then;)

Today's sun and its giant spot. Today we use 2.5xPowermate instead of 2xBarlow. I think the resolution is better, the picture is a bit smaller than with 2xBarlow. The atmosphere was pretty restless. 3/4 of the pictures were thrown away. Lastly, the protuberance training description. 10x the shutter speed compared to the full image.

The sun of the day. The shape of the heart is no longer with a big comma. A small gray cloud was interfering with the filming, but otherwise the atmosphere was calm. There was no need to throw the pictures away like a couple of 80s. Here's a quick read on the laptop screen. You need to make new ones when you get back to the calibrated screen. EDIT: Image reprocessed at the right monitor. The number of images was also reduced more. There was also some miracle disorder at the top left in the previous pictures. I left the CCD camera in the picture of the blooming disturbance, otherwise the ni...

After a day of sleet, the clouds faded. The giant dot is curled behind the sun, the surface of the sun is relatively featureless but a huge protuberance is visible. A big dot there releases its steam.

The sun of the day. Partly cloudy at the time of shooting. The picture shows only one 0.01s exposure. In the other pictures, there was too much cloud cover. The time to boot the equipment was even brighter when I watched the sun visually. A few times, the bird also flew in front of the sun. I wish there was a camera shooting at the time. Well sometimes the second one was at least fun to watch.

I was thinking of putting this of my first sun image from 2014 here in the archives of the Sky Watch. The number of sunspots was a staggering 199 according to Spaceweather. It was a hot and sunny July day at the association observatory in Meteoriihe. The CCD camera did not have cooling on. According to FITS data, the cell temperature was + 26C Star photography can sometimes be a hot picnic event;)

The sun of the day. The clouds did not disturb today, but the atmosphere was restless. 3/4 of the pictures were thrown away. The first two images with a CCD camera. The other two pictures I now tried to take wisely. Sony a5000. Only the red channel is taken in the pictures. I exposed the images so that the red channel did not burst. There had to be considerably less exposure than what the camera’s liveview clipping looked like. The video recording only became a foggy stack. Pretty close to the wit you got though, here it makes no sense to take narrowband photos with a color camera.

Sunscreen experiment with camera optics. There was a tired basic solar filter film for sequential optics. For a long time one comma is appearing. Cropped and uncropped image. Not a godfather but a fire to try. Wavelet and Lightroom finishing touch

The camera was shooting northern lights. At the end of the moment of observation, a small but bright stellar flight was visible. It was pretty good to the naked eye. Here's a croppy picture.

The pollen ring was seen for the first time and was quite powerful. Best seen with sunglasses.

Pollen perimeter photographed near sunset. The picture also shows the Raippaluoto bridge. There is only one small gap between the trees at the Rapatunturi shooting site towards the sunset. Now it 's' past' the shooting gap. Probably a month from now while you can describe the decline.
