This image highlights the region of the Bubble Nebula NGC 7635 (lower), and the spectacular open star cluster M52 to the left. The peculiar Bubble Nebula is thought to have formed from the stellar winds of its massive central star (BD+602522). This exciting region is located in Cassiopeia. A hydrogen alpha filter was used to record the extensive background emission cloud in the region.
