Here is a scan of a 30-minute exposure of the veil nebula and Pickering's Triangle that I took at Stellafane. Something is obviously wrong with the scan, and I don't know if it can be fixed by processing or not. The scanner I used probably isn't very good; it isn't a dedicated film scanner. I have had success scanning my black and white tech pan shots, but I have never dealt with color negative scans before.
Thanks and clear skies.
