Moon - 23.8.2021 at 22.30 - 23.8.2021 at 22.45 Ulvila Observation number 100733

Visibility V / V

Vesa Puistovaara, Porin Karhunvartijat

The idea was to get the Moon to rise above the horizon in the picture, but the abundant Cloudiness watered down my idea.

However, the picture shows a rather low, ~ 3-4 degree height using an h-alpha filter.

A total of 100 pictures, half of which are stacked in the picture.
