With a total of 125 minutes of exposure, the result overcomes the limitations of light pollution in many respects. The worst problem I had to deal with was the lack of a flat field - I only had the camera three days and never got a flat to cover this filter combination. With light pollution, good flats are essential. I did some quick adjustments manually in Photoshop, but the image really deserves a more careful manual flatting for optimal results. That will have to wait until I have the time!
