Another shot at processing the Great Nebula

The issue is that I am working with a stack of only 3 images for a total of around 150 seconds of exposure--a very small amount of data.  I did some more reprocessing of the image I posted earlier, reducing noise and manipulating levels.  This is the new result.  I think the center of the nebula is improved tremendously.  The rather grainy nature of the outer area is caused by insufficient data due to the relatively short exposure time,
