M92 | The Other Hercules Globular Cluster

With M13 so close by it's easy to skip over M92. But M92 is just as pretty if a bit less extended. Interestingly, as Earth's north pole precesses through its 25,700 year cycle, for a time this cluster sits almost as close to the pole as Polaris does today. This last occurred a bit before mankind invented agriculture - 10,000 BC. Although at magnitude 6 it makes a pretty poor Pole Cluster...

120 second subs were used along with the QHY Extended Full Well Capacity mode to retain color in the stars. The nights were quite sharp and the Luminance master had a FWHM of 1.5"

There are a few very red stars in the image. I'm not sure if those are artifacts of my processing or carbon stars. I do see some papers on known carbon stars in the area of M92 but did not verify the locations relative to my very red 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.
