NGC 6144 is a globular cluster in Scorpius. In some ways it is the “other” globular cluster in Scorpius since it is about one degree away from Messier 4, its better known cousin.

There isn’t much I can say about this one other that that. It has a much lower stellar density than most globulars. I couldn’t find any distance information on it.

This is 16h 40m of RGB data. You can find all the technical details on astrobin.
