Sun

12.3.2022 at 13.00 - 14.00 - Valkeakoski (V)
Veli-Pekka Käkönen, Tampereen Ursa

The first clearly warm day and best of all in the Sun a reasonable number of spots that I was excited to describe. Here are a few pictures of the above commas.

Penumbral lunar eclipse

10.1.2020 at 19.08 - 23.12 - Valkeakoski (II)
Veli-Pekka Käkönen, Tampereen Ursa

Description of the lunar eclipse in Valkeakoski. The moon shone from the clear sky at a temperature of -5 degrees. The event itself wasn’t a hair lift, but I hadn’t photographed the lunar eclipse of the Moon before, so I decided to try my luck. Attached is a summary of the main stages on the timeline.

Partial solar eclipse

11.8.2018 at 11.48 - 12.45 - Valkeakoski (IV)
Veli-Pekka Käkönen, Tampereen Ursa

The partial solar eclipse was very well visible throughout the event from the cloudless sky in this Valkeakoski. This time I photographed the course of the eclipse from beginning to end. A gust of wind slightly shook the imaging tube from time to time, but did not bother me too much. The picture shows the course of the event from the bottom left at 11:48, 11:50, 11:58 12:06 in the middle 12:16max, 12.25, 12:36, 12:44 and 12:45 end

Several bright halo forms

5.1.2016 at 11.00 - 14.12 - Pirkkala (III)
Veli-Pekka Käkönen, Tampereen Ursa

The first halo photos I ever took, showing the side suns nicely. I don’t understand much about halos, but these were especially great. The pictures were taken in Pirkkala and in Tampere's Hallila with a mobile phone camera. Annoying when there was no better camera on the way, the magnificent halo phenomenon that was. The brightness varied, but was particularly long in duration. The first pictures I took at 11:00 and the last at 14:12

Total lunar eclipse

28.9.2015 at 05.22 - 05.52 - Valkeakoski (IV)
Veli-Pekka Käkönen, Tampereen Ursa

I described the "Super" lunar eclipse in Valkeakoski under a very cloudy sky at times. Just when the eclipse was approaching its most perfect stage, the sky opened and the lunar eclipse was very nice :) Here is a picture of the perfect stage at 05:47 The eclipse was very spectacular looking and this time the color of the moon was very dark. Maybe on the Danjon scale, class 2 or even 1. EDIT: 29.09.2015 The image was translated to correspond to the visual view. EDIT 2: Time for full blackout and duration of blackout visibility added.

M31

23.8.2015 at 01.00 - 04.30 - Valkeakoski (V)
Veli-Pekka Käkönen, Tampereen Ursa

The first observation night in August and the target of every fall's "must" destination is the Andromeda Galaxy. I think the subject is always just as dumbly beautiful, that's why I photographed it again :)

Sun

9.8.2015 at 14.45 - Valkeakoski (IV)
Veli-Pekka Käkönen, Tampereen Ursa

At the moment, a rather large comma SP2396 is visible in the sun, which I also described for a moment from the cloud gap. The image is also my first light with the DBK31AU03. AS camera, which I purchased recently used.

Partial solar eclipse

20.3.2015 at 11.00 - 13.15 - Valkeakoski (IV)
Veli-Pekka Käkönen, Tampereen Ursa

A description of the solar eclipse by the lotila shore of Valkeakoski. The clear weather favored the celestial event for once. There was a little cloud gauze at times but it didn't bother at all :)

NGC 2237

15.3.2015 at 00.10 - Valkeakoski (II)
Veli-Pekka Käkönen, Tampereen Ursa

I photographed Rosette fog, which is sadly covered behind trees in my yard and can be photographed for quite about 1 hour at midnight above the neighbor’s roof. It was as if I got something to grip the camera cell too. My First Picture of Rosette :)

Jupiter

14.3.2015 at 21.20 - Valkeakoski (IV)
Veli-Pekka Käkönen, Tampereen Ursa

I photographed Jupiter from my backyard and Ion’s passage with his shadows was recovered again. The weather was pretty good this time and seeing at times even really good.

Jupiter

16.2.2015 at 20.27 - Valkeakoski (IV)
Veli-Pekka Käkönen, Tampereen Ursa

I photographed Jupiter on February 16, 2015 in slightly windy weather. Seeing varied from satisfactory to miserable during the filming, but, for example, the passage of Ganymedes in front of Jupiter grabbed the cell and the shadow it cast.

NGC 1499

14.9.2013 at 01.30 - Valkeakoski (II)
Veli-Pekka Käkönen, Tampereen Ursa

At the end of 2012, I first tried this dim red gas nebula in the constellation of Perseus. I used to shoot with my achromatic tube for guiding, but now I had a quality quadruplet I bought last spring. In the middle of the descriptions at about 1:34, I saw a fire exploding in a very bright green part of the eastern sky, slowly descending perpendicularly from the sky to the horizon. My observation without a picture can also be found in the Star of Heaven.

Saturn

1.4.2013 at 03.45 - Valkeakoski (III)
Veli-Pekka Käkönen, Tampereen Ursa

Saturn at a low altitude of about 15 degrees. Hard to describe in my backyard, disturbed by heat radiation from trees and houses. However, something grabbed the cell as well.

NGC 7000

13.11.2012 at 21.00 - Valkeakoski (II)
Veli-Pekka Käkönen, Tampereen Ursa

The Canon 60Da experimented again when once clear skies made it possible. This time the target is NGC 7000 in the constellation of Swan, or the North American fog. A good place to test Canon's ability to capture the red color of the Ha emission line. A bigger picture can be found on my blog: http://ällapesa.blogspot.fi/

NGC 1499

8.11.2012 at 23.00 - Valkeakoski (I)
Veli-Pekka Käkönen, Tampereen Ursa

My first nebula photo of the California nebula of the Perseus constellation, taken from the light-polluted sky of Valkeakoski. At the same time, the new Canon 60 Da camera and its ability to record red wavelengths were tested. There was so much light pollution that, despite numerous attempts, I couldn't get my eye on the target at all.
