NGC 7635--The Bubble Nebula--in Cassiopeia
NGC 7635, otherwise known as "The Bubble Nebula," is located in the direction of the constellation Cassiopeia. The bubble is formed by the solar wind of a large--about 15 solar masses--central star. It is somewhere between 7000 and 11000 light years from earth and the bubble is about 3-5 light years in diameter. The data for this image was captured at the General Nathan Twinning Observatory (GNTO) in Belen, New Mexico on 10-10 and 11 of 2015 using a Celestron 11" HD Edge with f/7 focal reducer on a Losmandy G 11 mount. The camera was an SBIG ST4000XCM one-shot color camera operated at -10 C. Guiding was done using the in-camera guide chip and CCDSoft. Two hours and forty minutes of exposures were combined in DSS and processed in Photoshop.
