Dark space with red nebulas and a bright star cluster.

3 in 1. The Bubble Nebula is in the middle, the Northern Lagoon Nebula in the lower left, and the open star cluster M-52 is in the lower right. These objects are not physically related even though they are in the same area of the sky. They range between 5000 to 9000 light years away. The "bubble" stands out and is created by strong powerful stellar winds pushing against the molecular gas. The image is compose of 325 stacked frames totaling 5+ hours of data.
