The Great Hercules Cluster wide field

Got just over 2 hours of data on M13 with my little scope (81mm), waiting on another target that I am working on. Nice night, low winds and fairly dark skies. Tried processing this image 2 ways. 1) Combining LRGB data with APP and 2) Combined RGB data in APP and then adding the Lum layer in PS. The 2nd process actually made for the better image.

M13 is one of the brightest deep space targets (5.8 mag) and is easy to observe with a decent telescope. M13 is relatively close (25K light years away) and contains between 250K and a million stars. M13 is estimated to be over 12 billion years old, just a bit younger than our Milky Way galaxy.

The Astrobin Plate solve showed 5 galaxy's, I had noted 2 close to the cluster, but missed the one up top. I did crop this image a bit, I might load the even wider FOV version to see if their were any other galaxies detected.

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.
