Explanation: In 1716, English astronomer Edmond Halley noted, "This is but a little Patch, but it shows itself to the naked Eye, when the Sky is serene and the Moon absent." Of course, M13 is now less modestly recognized as the Great Globular Cluster in Hercules, one of the brightest globular star clusters in the northern sky. Sharp telescopic views like this one reveal the spectacular cluster's hundreds of thousands of stars. At a distance of 25,000 light-years, the cluster stars crowd into a region 150 light-years in diameter. Approaching the cluster core upwards of 100 stars could be contained in a cube just 3 light-years on a side. For comparison, the closest star to the Sun is over 4 light-years away. The remarkable range of brightness recorded in this image follows stars into the dense cluster core. Distant background galaxies in the medium-wide field of view include NGC 6207 at the upper left.

A galaxy without a Black Hole..........................yet................
“oh my god — it’s full of stars”

Hey! I was looking for that just the other day! Glad you found it.
I don't know. We had a black hole in the White Hut.
Great Balls of Fire!!!
The only time I’ve ever seen it (ngc 6207), was in our club’s 10” f/13 refractor, with averted vision. That was years ago, when the skies were darker. Now we have a BMX track across the street, and in the summer, everything is lit up like daytime.
Progress…
I had a globular cluster removed last year. It was quite unpleasant.
Nice view from a nearby planet but the radiation would be a killer.
