This is the globular cluster in Hercules that isn’t M13. Actually to be fair, there are others but this is the only other globular in the Messier catalog that is in Hercules. This one gets a lot less attention from amateurs than its more famous cousin but it is still worth a peek.

The cluster is about 26,700 light years away and like all globulars it looks like a progressively less dense ball of stars.

This is 3 hours of RGB data. You can get the technical details at astrobin.
