Bubble NGC 7635

NGC 7635, also called the Bubble Nebula, is an emission nebula in the constellation Cassiopeia. The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow. However, I had been unsuccessful in drawing out detail with the Hyperstar and the C1400. I decided to image a lot longer...60 images of 30 sec. I set up the camera with Maxim DL to do just that, and left for 45 minutes, going home to watch TV/ When I returned, I realized that the scope had tracked to within the edge of my ExploraDome's opening, thus causing a reddish hue to the right side of over half of my images. I decided I wanted the exposure time, so I used Gradient Exterminator to get rid of the coloration. After several manipulations in Photoshop and some cropping, here's the result.
