Photo description / processing

Another playful session from the city under a bright sky. But at least it offers a chance to compare possible changes from last year. Made a GIF—most likely just variable stars.

Information about the sources is below in the grouped photos. Hmm, I was wondering—if anyone else has time-lapse photos too, compare them to see if there are similar changes in the brightness of individual stars against the background of the others.
