M13 - 23.7.2021 at 01.28 Turku Observation number 99952

Visibility III / V

Over the weekend, I also got to start filming DS subjects from my balcony but had to wait until one night until Messier 13 would be at a more appropriate height and the balcony roof would not be in front of it to interfere with the shots. So I shot the subject for 4 nights in a row and in total I took the exposures for a little over 5 hours.
