Jupiter

6.8.2021 at 23.00 - 02.00 - Hämeenlinna (III)
Veijo Timonen, Ursa (Etelä-Suomi)

I tried to shoot Jupiter and Saturn at the maximum magnification that the Celestron C11 telescope gets. The tube had an additional 2 tele-extensions in a row. However, a lower magnification would have been better because the cloud front from the south was disturbing. Then I tried an ir pass filter for Saturn, which reduced atmospheric variation. Infrared imaging was a modified Canon 6D The original video frames can be found at that link. https://avaruus.kuvat.fi/kuvat/2021/Avaruuskuvat/ The planets are packed with RgiStac. 2000 video frames.

Lightning photo

23.6.2021 at 15.20 - 15.30 - Hämeenlinna (III)
Veijo Timonen, Ursa (Etelä-Suomi)

In Hämeenlinna, lightning flashed for about a minute. From which I made a video, and from that a gif animation.

Total lunar eclipse

27.7.2018 at 23.30 - 01.10 - Hämeenlinna (IV)
Veijo Timonen

The eclipse began to appear as soon as the earth's shadow had completely covered the moon. The first part would not have been fully visible in Hämeenlinna when the moon was below the horizon, the clouds also covered the horizon a bit. Had to do a little jerk, the shooting equipment was ready on the balcony, I thought this would not work. I took the cameras off to stop shooting. Little Tuko, and the clouds left immediately. When I came back to the balcony to photograph, the ISS walked near the moon (filmed there) so I also photographed the already darkened moon. https://www.youtube.com/watc...

One halo form

23.1.2018 at 09.04 - 09.23 - Hämeenlinna (I)
Veijo Timonen

The sun rising next to Mount Kappolon announced in good time that they were coming from here. And it didn't help but start filming. A frost of about 10 degrees and ice charred caused that solar pillar.

Jupiter ja Mars

7.1.2018 at 07.30 - 08.30 - Hämeenlinna (III)
Veijo Timonen

In the morning before eight I was able to photograph Jupiter and Mars encounter in the southeast and south. Fitted on a 1300mm telescope image both. Focusing was a bit tricky with a lightweight tripod for about a long focal length. I wanted the moons of Jupiter included, so they had to be illuminated separately with a longer exposure time.

Kuunpimennys

7.8.2017 at 21.30 - 22.15 - Hämeenlinna (IV)
Veijo Timonen

The moon rose behind Kappolonvuori in Hämeenlinna, already partially covered. I filmed this for about half an hour. I put the Canon 6D into video shooting while at the same time snapping single images with another camera. Here is a link to the video https://www.youtube.com/watch?v=J6ww3bLOK-g&feature=youtu.be

Lightning photo

17.7.2017 at 18.16 - Hämeenlinna (IV)
Veijo Timonen

For the first time this summer, I heard a thunderstorm in Hämeenlinna heading east. I tried a 4K camcorder with which I hoped I could get a flash of the flash to capture some single frame of the video. I stopped recording whenever the flash fired, when the desired frame was found was always the rest of the video. The selected frame can then be saved directly to the camera as a jpg image.

Venus

23.3.2017 at 09.30 - Hämeenlinna (II)
Veijo Timonen

Venus is just 8 degrees above the sun. I covered the sun by taping the cardboard on the balcony glass as shown in the picture. The sickle is clearly visible with binoculars. But it’s worth watching while the Sun is still below the horizon so you can see better. https://www.youtube.com/watch?v=R0xpHUVlc90&feature=youtu.be

Telescopic comet Honda-Mrkos-Pajdusakova

22.2.2017 at 01.17 - Hämeenlinna (I)
Veijo Timonen

I stacked those exposures according to the stars. So I got the stars better, but the comet’s tail suffers. Without the UHC filter, I wouldn’t have gotten anything out of it when there’s extra light in the shooting area. #pyrstö 55 'PA 290 °

Rare halos

4.12.2016 at 11.00 - Hämeenlinna (IV)
Veijo Timonen

At about half-past ten, side suns formed, and after half an hour, a solar pillar began to form. Later it was followed by a V-shaped halo inside a 22 degree ring. A small snippet of the movie is at that link: https://www.youtube.com/watch?v=jWCKD-ckLjc&feature=youtu.be

Vihreä välähdys

28.12.2015 at 09.35 - Hämeenlinna (II)
Veijo Timonen

The sun rises at this time for me from that lowest point on the horizon. The top of the sun was only 00.12 degrees. Making that green flash possible to see. I dipped the 600mm + 2X lens in the backlight shield with a separate iris dimmer with only about a 3mm hole left. A small image has been added from the video frame.

One halo form

19.12.2015 at 21.24 - Hämeenlinna (I)
Veijo Timonen

A 22-degree filmy bluish halo ring formed around the moon. I photographed from the balcony facing south, there is multi-colored light, so I made a white balance setting on that edge of the balcony. To the eye, that halo looked a little bluish, but maybe not quite that strong. I exposed that image for 14 sec. So the crescent moon seen at the time was overexposed.

Binocular comet Catalina

8.12.2015 at 06.30 - Hämeenlinna (III)
Veijo Timonen

I photographed this on 8.12 at about 6:30 when it was still dark. I could see a little bit with the naked eye. The approx. 200mm camera with lens doesn’t bring out very well yet. And especially when I didn’t want to shed light on Venus and the Moon erupted.

Binocular comet Catalina

7.12.2015 at 06.50 - Hämeenlinna
Veijo Timonen

It was the first attempt to describe this comet in slightly cloudy weather. With a 300mm lens, Venus fit in the same field of view (Large image.) With a 1000mm tube (small picture), both tails of the comet came out, on the other hand, the clouds also suitably gave way. I also tried to look with binoculars, but I didn’t get the observation, there was maybe too much cloud gauze.

Partial solar eclipse

20.3.2015 at 11.00 - 13.15 - Hämeenlinna (IV)
Veijo Timonen

In Hämeenlinna, you could photograph and watch the solar eclipse through a thin overcast cloud. I took this picture with a 50mm lens every 5 minutes. In the full-time camera High 125 sensitivity, which did not need to be corrected during the entire period, exposure 1/250 sec.

Venus ja Jupiter

18.8.2014 at 04.16 - Hämeenlinna (III)
Veijo Timonen

Venus and Jupiter were less than the diameter of the Moon apart. It would have fit well in the image field of the 1000mm telescope with both, but not close enough to get a decent magnification of the same image.

Clearly visible night shining clouds

2.8.2014 at 02.30 - Heinola (III)
Veijo Timonen, Hämeenlinnan Vega

Bypass Heinola north of the bridge.

NGC 7000

27.7.2013 at 01.00 - Vihti, Ojakkala (II)
Veijo Timonen

During the Cygnus days in Vihti, I tried to photograph the Swan (Cygnus) region from a slightly light sky. The descriptions of the deep sky have not been tried before in July. But in a test sense, I wanted to test the effect of the H-alpha filter. The lens was a Nikkor 80-200mm 1: 2.8 with an H-alpha filter. Sony Nex-5 Big 800 with approximately 60-180 second exposures.

Binocular comet PANSTARRS

14.3.2013 at 19.50 - Hämeenlinna (III)
Veijo Timonen

The comet was found at an altitude of about 3-5 degrees on the horizon of Hämeenlinna. I didn’t try to look very closely with the naked eye or with binoculars, I focused on shooting. And it's easy to grab a camera with a 0.6mm exposure with a 200mm lens. The wider 16mm image shows up rather poorly. The comet was about 3 degrees above that level.

Telescopic comet LINEAR

5.1.2013 at 18.30 - Hämeenlinna (I)
Veijo Timonen

Comet 2012 / K5 Linear was in the lower part of the Driver's constellation on 5 January 2013. I chose the description as a Nikkor 80-200mm (130mm) lens with which I got those nebulae IC 405 and IC410 at the top of the picture in the same picture. The brightness is probably in the comet at about 10 magnitude orders of magnitude. During the shooting, the cloud rafts of the assembler were moving so I was only allowed to take a few short exposures.
