Wide Field around Messier 92 globular Cluster & faint galaxies in Hercules

M92 is a old globular cluster in Hercules, the second brighter behind the oustanding "Great Globular Cluster in Hercules" M13. If we compares the two globular clusters, M92 is a bit fainter (6.5 vs 5.8 mag) farther ( 26000 ly vs 22000 ly), and smaller in size (100 ly vs 145 ly)

M92 is a class IV globular Cluster, although M13 is only a class V, that is to say a rather dense cluster but one order less. Their absolute magnitude are similar (-8.21 vs -8.55), around 100 000 - 200 000 suns.

Its age is estimated around 16 billions of years, thus much more than the universe ! But its distance is may be over estimated of 10 %, leading to a 15 % overestimated age.

In 14000 years, M92 will be aligned with the polar axis of the earth, because of the precession of Earth's axis.

Farther behind, tens ofgalaxies appears on the right, up to magnitude 18. But the small refractor used, the quite polluted sky (SQM around 19) didn't succeed to reveal them all. In fact, Hundreds of galaxies could be detected with a 10 inches telescope and a dark sky, up to magnitude 21.

For example NGC6329 is around 120 Mly of earth.

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.
