NGC 7635- Bubble Nebula

NGC 7635 - Bubble Nebula

The Bubble Nebula is created by the force of a  stellar wind of a massive central start.  Next to the nebula is a large molecular cloud.  The cloud gets blasted by the high energy of the star and is pushed out to form this bubble and glows.  The Bubble is thought to be about 10 light years in diameter and is located in the constellation of Cassiopia.  I took this photo in October of 2007.  We had a week of clear weather.  I was able to continue to photo each night and accumulate about 26 hours of exposure through narrow band filters.
