July 12–19, 2012: Open cluster M18 in Sagittarius offers small-telescope owners nice views, while large-telescope owners can seek out globular cluster NGC 6584 in Telescopium and spiral galaxy NGC 6221 in Ara.

NGC 6221 lies only 25' east-southeast of magnitude 3.8 Eta (η) Arae, so when you view the spiral, be sure to move the bright star out of the field of view. Astronomy: Roen Kelly
