NGC 7635 - the Bubble Nebula is a ghostly emission nebula in the constellation Cassiopeia. It is approximately 10,000 light years away from us.
I wanted to add more exposure to my Aug 5/6 session on this nebula at the DAO and the dark skies on Monday night Aug 13 at Cypress Hills following the star party provided the opportunity. The attached is the result of combining exposures from both sessions. The extra exposure resulted in more subtle detail and lower background that I had from the first session alone. This version has been reprocessed using PI.
