Here's a new version of m104 with about three hours of grossly oversampled unbinned luminance that nevertheless seemed to work all right. The net result off course is a larger higher resolution image. I also followed Mike's recommendation and rotated it 90 degrees. It does seem to look better this way.
Cheers
