The Bubble Nebula
The Bubble Nebula really is a bubble within an expanding molecular cloud, carved out by the stellar wind of an extremely hot and energetic star. It lies about 11000 light years distant in the constellation of Cassiopeia, and is nearby the beautiful open cluster M52.
This image was taken with a Stellarvue SVS130 telescope and an SBIG STL-4020M CCD camera. Hydrogen-alpha was used as the red channel, while the blue and green channels are Oxygen-III. The image was processed in MaximDL and Photoshop, and was upsampled 2x.
