At least 10 lightning strikes seen - 17.8.2022 at 15.49 - 17.8.2022 at 16.20 Tampere Observation number 108661

Visibility IV / V

Markku Lintinen, Tampereen Ursa

As the thunder front approached, I thought that the series of maximum stacks that worked for the Perseid photo might work for the lightning photo. I adjusted the north camera to a faster 20 fps for the duration of the shoot. There was still one finishing touch left to try for the next shooting: the gain of the sensitive sensor should have been adjusted to the minimum, so that the exposure time would have been even a little longer. Now, many flashes were probably not captured, even though the video turned out to be a total of more than 100,000 images to be stacked and these flashes to be picked from the stacks.
