Bubble Nebula and M52 Open Cluster

The Bubble nebula or Caldwell11 (bottom right) was discovered in 1787 by William Herschel. Located  in the constellation of Cassiopeia its about 11,000 light years away and totally unrelated to M52 (top left). The bubble is caused by the stellar wind from a massive, very hot, young star which disturbs the giant molecular cloud that surrounds it, making it glow. It seems to sit in a fan shaped void.
M52 or NGC7654 was discovered in 1774 and is about 5,000 light years away. Its relatively young at 35 million years and contains 200 stars with a diameter of just 19 light years. It also contains another very small cluster HIP115521 and a white giant star HIP115542.
The image is rich with stars as the view is through our own galaxy, the Milky Way
The image was generated from 20 light frames, 10 dark 10 Flat and 10 Bias frames. exposure was at ISO 1600 for 150 seconds giving 50 minutes. Scope was an ED80 @ 510mm focal length. I'm really please with this image as its very faint and small, taken with an unmodified old dslr.
