Galactic Nebula NGC 6820: Close to the Dumbbell Nebula M27 is this not very often photographed emission nebula. Typical for a star generating region is the huge trunk-like structure within the nebula which is created by the strong radiation and star winds of the young Open Cluster NGC 2623 in the center.
