Re: M20 with Mario's gradient correction process
Following Monday's GAAC photo Zoom, I decided to try the GradientCorrection process Mario explained and demonstrated to us.
I picked my photo of the Trifid- M 20 to redo because it aways suffered from a nasty gradient in an upper corner which DBE could not eliminate.GradientCorrection made it go away. t was then easier to push the stretch of the image. Of course, I also used BlurX and UnsharoMask to bring out the detail.
I was amazed at how much more of the blue reflection nebula was revealed, and (surprise) a "pillar of creation" feature emerged on the lower side of the red emission nebula component. It is pretty obvious when you look at the photo. Also, the stars are true pinpoints now (thanks to BlurX) which was difficult to achieve previously, given the southerly location of this object.

Very nice Phil, great detail and color
One of my projects will be to reprocess some of my images, like I did with m51…
But there always seems to be even newer and better process techniques!

Thanks, Mario,
Processing is certainly accelerating Mario, and I thank you for keeping all of us aware of the progress.So much tedium is gone now (such as using the old standby DBE).I suspect the day will eventually come (for better or worse) when you "dump" your subs into a window and seconds later a finished, impressive image appears.
