Nice work Ron. I will say the focus looks a little soft to me. Also, I think for all the time you have on this there should be more dust in the areas outside the nebula. I am still working on a bi color version with only 2 hours and Ha and 2 of OIII. You can see it here: https://www.flickr.com/photos/49526053@N04/14600075395/in/photostream/lightbox/

If you want to see an absolutely amazing version, check out Bill Snyder's which won him an APOD.
