After my first astrophotography session for almost a year, I chose M13 to have a fairly simple target as I expected I'd struggle with numerous technical issues which would reduce my overall exposure time for the night. I was wrong: setup, calibration, guiding and exposure all worked very well. The only obstacle was a pretty strong wind and numerous high clouds which in the end caused me to exclude 40 of the 136 1-min-exposures.

One interesting event occurred to me during observation. At about 1:30am local time I spotted an object that periodically blinked whitely at a 24 seconds interval and at about 2mag brightness in constellation Hercules that moved very slowly (perhaps 1 degree in 2 minutes) across the sky in West direction. Certainly not an airplane and not a satellite. I'd say probably some sort of weather balloon. Pretty weird.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
