The Great Globular Cluster in Hercules.
The 13th object catalogued by Charles Messier in 1764.
Visible as a smudge with the naked eye in dark skies.
Not much to look at visually IMO, but a fascinating object in the universe.
Clusters are the result of Immense gas clouds that form incredible numbers of stars in a compact area. There are hundreds of clusters in our Milky Way.
In this case 500,000 stars which occasional collide to form more stars.

2 hours last night, 700mm scope with 533 camera.
PP mostly in Pixinsight.
Resolving the stars in the biggest challenge with these clusters.

It's cool to see it with this much magnification which shows why it looks like a washed out star to the naked eye.

Thanks for the explanation, Dan, makes it even more interesting than it is to begin with.
