M13 - Great Hercules Globular Cluster (primaluce)

This image is the first light of my new Askar 107 PHQ. I still have to improve something with the guide, probably adding a counterweight will help the RST135 to better manage the approximately 12 kg of this setup. The evening was also very humid and the sky was not perfectly clear. I think there is still some room for improvement in ideal conditions.

M13, also designated NGC6205 and sometimes called the Great Hercules Cluster, is considered the most spectacular globular cluster in the northern skies.
Discovered by Edmond Halley in 1714, it was cataloged by Charles Messier in 1764. It is barely visible to the naked eye on dark nights and appears so large and bright because it is actually large and bright

and also relatively close, at around 25,000 light years. M13 probably contains more than a million stars and has a diameter of 165 light-years

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.
