The Great Hercules Cluster M13 / NGC6205 is the colossus of globular clusters visible in the northern hemisphere. It can be seen with the unaided eye from a dark sky site which is not our roof top terrace. It packs about a half million stars in a region only 150 light-years across, orbiting our galaxy like a giant satellite 24000 light-years away. The brightest stars in this image are red giants, thousands of times brighter than our sun. At its core, the glare of brilliant suns would obscure the remainder of the universe. Of course, planets are unlikely in the center of a globular cluster, as frequent gravitational interactions with other stars would strip away planets.

This is our first attempt of a globular cluster which was imaged over two nights with nearly a full moon. We are not sure, stars are oversaturated. We got 112 frames out of it (76 good ones).

In post-processing we tried to work out stars in the center but not dim down the rest of them. The small galaxy in the upper left is a cutie too. We would have liked it, if we could invest more integration time. Hope you like it! Comments and critique are very welcome!

Cheers

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.
