M15 is the second object as part of my imaging with pneumonia series. I was not planning to image with pneumonia - I took this last week when I thought I had a small nasal infection. It was taken after I completed NGC 6934 while waiting for Andromeda to appear. I captured the red and 10 green subframes on 10/13 and finished on 10/14. I was not planning on imaging this although my last image of M15 was a 30 minute exposure from three years ago. Needless to say this image is much better. Like NGC 6934, I was happy how the background turned out. I have never been truly satisfied with my images of globular clusters possibly because I have such a small aperture telescope so I am always happy to get a good background. So far I could not be any happier with my new camera. Also, for those who notice orientation, it is not E-W or N-S because I have my camera set approximately 25 degrees off in order to capture Andromeda and Triangulum when I get to it. I haven't touched my camera so I can easily image over days or weeks.
