BEHIND THE IMAGE
Notes from the session
Source: Wikipedia
I knew this would be a very difficult target from a city location, but 29 hours of image integration time brought out the nebula from the noise. Unfortunately the bright nearby star Rigel played havoc with internal reflections in my equipment. Most of the time processing this image was to try to remove the reflections.
