M92 - The Other Beautiful Globular in Hercules

M92 was first discovered in 1777 by Johann Elert Bode. Although it is often overlooked in favor of the nearby M13 globular, M92 is among the brightest globular cluster in the sky--both in terms of apparent and absolute brightness. It contains mostly hydrogen and helium with very little heavier elements. It's age is estimated to be 14.2 +/- 1.2 B-yrs, which is roughly the age of the universe itself. It is very interesting to ponder the mechanics that have kept such a tight cluster of stars from collapsing since the beginning of time.

This should have been an easy target but it wasn't. I've been fighting a lot of equipment/software gremlins that I've concluded may be due to a ground-loop in my wiring. I've got a solution pending but that's a story for another time. The net result of all of my equipment problems is that what should have been a quick one night project, stretched out over 5 nights of effort. Taking data over so much time really makes it hard to quickly process the result since I had different seeing, sky brightness, and then the moon finally came up while I struggled to get enough data. This image is about 90% of the full frame from the 16803 sensor so it's a pretty big field for the C14E.

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.
