This image captures the area of sky around the super cluster - Westerlund 1. The cluster has attracted a lot of attention from astronomers due to the large collection of super massive stars from which the cluster is comprised. The cluster, and the surrounding areas, appear very red due atmospheric extinction caused by the clouds of dust in the Milky Way. This area of sky is located in the constellation of Ara in near the tail of Scorpius and close to the constellation of Norma. The image makes for nice viewing with the scattering of Ha regions and the distinctive dark nebula running across the image. The dark nebula kind of looks like a sea horse dance across the field of stars.
