From the 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.”
