M13 - 11.8.2020 at 00.01 - 11.8.2020 at 02.50 Järvenpää Observation number 92752

Visibility III / V

Ari Jokinen, Etelä-Suomen kosmol. seura

Opening image for this fall, the finest spherical in the northern sky. Not so dark yet but yes the description pretty well succeeds with at least a couple of hours of time window. However, the moon was a little disturbed this time, when the background sky was not the best for that either. In fact, this is probably the first LRGB image I’ve ever taken, so it goes to the peak of the exercise.

The gang has already taken some great pictures.
