NGC 6193 (also known as Caldwell 82) is open cluster containing 27 stars in the constellation Ara, visible to the unaided eye. NGC 6193 lies at the center of the Ara OB1 association, which extends over a square degree. The cluster is associated with (and provides the energizing radiation for) neighboring regions of the nebulosity NGC 6188.
Cluster members NGC 6193 is dominated by two O class multiple star systems within 10" of each other at the centre of the cluster, and a probable binary B0 giant. There are at least 20 other early B stars in the cluster, of 9th and 10th magnitude.
