         Object RCW132 and RCW133
         Comment Located in the constellation Scorpius are the emission nebulae RCW132 (aka Gum 67, Sh 2-12, LBN 1116) and RCW133 (aka Gum 68, Sh 2-13). These nebulae consist of ionised hydrogen excited by the star clusters of NGC6383 and Antalova 1 respectively. The clusters are thought to be in or near the Sco OB4 association. A study performed in 2005 determined that the central star of the cluster Antalova 1 (HD 158186) in RCW133 may be a runaway star ejected from NGC6383, the star cluster at the heart of RCW132. Left of center, the open cluster M6 (NGC6405) more commonly known as the Butterfly cluster. Lower right is NGC6357, the Lobster nebula. RCW132 is approximately 5,500 light years away.
