NGC 6193 (also known as Caldwell 82) is open cluster containing 27 stars in the constellation Ara, visible to the unaided eye.

[1] 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.

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.
