Messier 13 (M13; also, NGC 6205) is a Globular cluster of stars in the Constellation Hercules, and it’s also known as the Great Cluster in Hercules.
It’s visible in the Keystone asterism, formed by four brilliant stars in Hercules; M13 is visible under dark skies to the naked eye as a weak star.
The cluster is about 22.200 light-years away from us and it contains a number of stars estimate from around 300.000 to over half a million. It makes it one of the biggest clusters visible in the Northern Hemisphere.
Nearby to Messier 13 is NGC 6207, an edge-on spiral galaxy located about 30 million light-years away from Earth. Another spiral galaxy, IC 4617, lies halfway between M13 and 6207; it’s estimated to be about 500 million light-years from Earth.
After my first globular cluster (M3), I tried to use HDR. I think the result is positive and I'm going to try it also in other subjects such as galaxies or where there are bright stars.

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.
