From Wikipedia:
The
Wild Duck Cluster (also known as
Messier 11, or
NGC 6705) is an
open cluster in the
constellation Scutum. It was discovered by
Gottfried Kirch in 1681.
Charles Messier included it in his catalogue in 1764.
The Wild Duck Cluster is one of the richest and most compact of the known open clusters, containing about 2900
stars. Its age has been estimated to about 220 million years. Its name derives from the brighter stars forming a triangle which could represent a flying flock of
ducks.
