Starscape image - 8.8.2020 at 00.00 - 8.8.2020 at 00.30 Pieksämäki Observation number 92995

Visibility III / V

Timo Inkinen, Ursa (Etelä-Suomi)

Here are a couple of landscape constellations from early August, when it’s not yet properly astronomical dark. I went to Pieksämäki summer cottage on August 6-8, 202020 and photographed the night sky with Olympus 7-14 / 2.8 wide angle zoom just before midnight.

The first image shows a 14mm wide angle view of the cinema size south over the cottage pond. At the bottom of the horizon are the summer planets Jupiter and Saturn (reflected from the surface of the pond). Slightly higher up shine the three bright stars of the Summer Triangle, namely Deneb, Vega and Altair. At the top of the image, there are as many stars as the total exposure of 30x10s still brings out the summery light starry sky. This image is larger here .

The second image shows a view of zenith with a 49x10s exposure, which I treated as an approximately realistic view in a situation where no completely astronomical darkness is yet available. This image is also visible on my homepage at a larger size (2500 px longer page), as the 1000 pixel image of the Sky Guard is likely to hide the tiny little stars in this image.

Mood images mainly whose image processing was surprisingly cumbersome due to the large gradients in the wide image area.
