Liller 1, Sh2-13, RCW132 and M6

This region of Scorpius lies on the galactic equator.  At the upper right is the small red emission nebula Sharpless-13.  The much larger pale orange nebnula at the center of the photo is RCW132.  To the left of this nebula is the open star cluster M6.  At the lower (southern) tip of RCW132 is the invisible (in this photo) globular cluster Liller 1.  William (Bill) Liller discovered this globular cluster from the Cerro Tololo Interamerican Observatory in Chile.  At that time he was on the faculty of the Astronomy Department of Harvard University.
