The Bubble Nebula (NGC 7635) in the constellation Cassiopeia.

The Bubble Nebula (NGC 7635) in the constellation Cassiopeia. The "bubble" is created by the stellar wind from a massive hot 7.8 magnitude young central star. This image includes the bright nebula NGC 7538 at the top, and NGC 7510 to its right. M52 (NGC 7654) is at the bottom left. I haven't been able to find a name for the nebulosity on the right hand side of this image. [Edit - the Lobster Claw Nebula SH2-157 is nebula on the right side of the image]
