Messier 13 - The Great Hercules Globular Cluster

Revision title: M13 - wide field

Discovered in 1714 by the astronomer Edmond Halley, the globular cluster Messier 13 is situated some 25100 light years from earth in the constellation of Hercules and is said to be the most spectacular globular cluster visible from the northern hemisphere. With its 145 light year diameter and several hundred thousand stars, it is believed that at times M13 can become so crowded close to its center that stars collide and form new so-called “blue stragglers” that are more luminous and bluer than their older and cooler neighbours. The age of the Great Hercules Globular Cluster is said to be approximately 11.65 billion years.

Title: M13 - wide field

Description: Reprocessed with BlurXterminator2. The module definitely does a good job. I was batteling tilt here and it straightens that pretty much out, although the wavy diffraction spikes towards the edges certainly shows that something here is not right. I'll continue physically working on my tilt, but I do like the deconvolution job BlurX2 does. Anyway, I thought this was a cool exercise in order to highlight all the tiny galaxies surrounding the M13. Therefore I've tried to tone down the stars except for the ones in M13 to better spot the small fuzzy ones.

Title: M13 - Annotated

Description: The Annotate script doesn't pinpoint all the galaxies, it shows more than Astrobin's annotation.

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.
