Swan Nebula, reprocessed

Hi,

With the help of IIS members, I have reprocessed the existing 17 hours LRGBHa data using PI. Star colors are somewhat more natural, the nebula is still a little washed out, every attempt I've made to reduce brightness also removed surrounding red hue, turned it into blueish, so I left as it is.
The bottom 5th appears a tinge blue, I am not sure where it came from, more likely from cloud or FOV hitting dome edge during blue filter frames.

About 10Mb hi-re link: http://www.astrobin.com/full/51331/?mod=none

The attached image was taking from the screen with screen capture program, heavily cropped to fit allowable 200Kb. What would be the best way to save or create the attach image balancing size and quality?

Thanks
David
