Partial lunar eclipse

16.7.2019 at 23.30 - 00.30 - Kangaslampi (III)
Esa Heikkinen, Anni Heikkinen, Warkauden Kassiopeia

Partial lunar eclipse photographed at the Warkause Cassiopeian Härkämäki Observatory. This time the weather allowed observation. In addition to the observers, there was also a lot of mosquitoes on the site.

Total lunar eclipse

21.1.2019 at 06.55 - Varkaus (IV)
Esa Heikkinen, Warkauden Kassiopeia

Lunar eclipse from an almost perfect phase. The weather wasn’t completely clear and actually already during the shooting it started to get weaker. In the end, the most technically spectacular exposure was taken just shortly before the perfect phase. Pretty soon after taking the pictures, the sky started to cloud completely.

Telescopic comet Swift-Gehrels

3.1.2019 at 18.53 - Kangaslampi (IV)
Esa Heikkinen, Anni Heikkinen, Veli-Pekka Hentunen, Warkauden Kassiopeia

Another comet 64P / Swift-Gehrels was also filmed as a short clear section on Thursday night. 10 of these were taken. a series of 120-second L exposures, no more weather would have been enough. Like Wirtanen, this comet also appeared quite large, about 10 minutes of arc. The picture clearly shows maybe two very close jets of material to the left, slightly downhill. Image size 18 'x 23'.

Binocular comet Wirtanen

3.1.2019 at 18.02 - Kangaslampi (V)
Esa Heikkinen, Anni Heikkinen, Veli-Pekka Hentunen, Warkauden Kassiopeia

Outgoing Wirtanen photographed with a CCD and digital wit. In the second CCD image, the stretch of the image is knocked out as much as possible so that the entire comet material becomes widely visible. Wirtanen fills almost the entire field of view, thus being at least 20 arc minutes in size and perhaps slightly egg-shaped, so the tail could be right downward. CCD images are 18 'x 23' in size. Illustrated by Anni and Esa Heikkinen, processing of CCD images Veli-Pekka Hentunen.

Esa Heikkinen, Anni Heikkinen, Warkauden Kassiopeia

Northern lights have been seen in Varkaus for several evenings. The forecast pages are not necessarily these predictions, these were also described even though the predictions were not supposed to be anything very special to see.

Transit of venus

6.6.2012 at 07.03 - Varkaus (II)
Esa Heikkinen, Warkauden Kassiopeia

The passage of Venus was also monitored in Varkaus, on the shores of Komminselä. The thick cloud cover prevented detection quite effectively and made photography almost impossible. The first moderately successful images were not obtained until after 7 o'clock, but even in these the sun was not clearly visible, but partly behind the cloud. The changing Cloudiness made e.g. difficult to adjust the shutter speed, a large number of shots were either overexposed or underexposed when the setting suitable for the previous image no longer applied to the next one at all. The sun was usually only vi...
