Longest time I have spent on an object to date. It was truly an all night imaging session (10pm to 4:30am) and from that a lot of detail in the background is evident for a DSLR. If you look in the top left hand corner area there is a small galaxy (PGC 46922) which TheSkyX lists at magnitude 15.44. Deep Sky Stacker took an entire day working through the 500 frames needed, which made my poor little net book really suffer. In the end I am really proud of this image but really suffered from the lack of sleep.
