M6 - The Butterfly Cluster 1 & 2

Discovery first recorded by Giovanni Battista Hodierna in 1654

M6 is known as the Butterfly Cluster.  Robert Burnham discribed the cluster as a "charming group whose arrangement suggests the outline of a butterfly with open wings."  The cluster is classified as an open star cluster in the southern constellation of Scorpius approximately 1,600 light-years from the Earth.  The cluster is dominated by bright, blue, B-type stars, however; contrasting with its neighboring blue stars is the giant orange K/type BM Scorpii.
