Ok, Ill see if i can download a trial.  I only needed a very mild application on this one, the grain only was seen at large sizes because the sn was great.

 

Clear Skies,

Hi Chris

 

Beatiful image! Congratulations. I think that the overall balance is a little too red, but I remember that it is like an issue of Supra 400.

 

In your description I saw that you used SGBNR. Give PixInsight LE a try. The SGBNR algorith is optimiced (faster and a bit more accurate). Also working with the CIE L*a*b* channels is most cases returns better results, and it's easier to find the correct paramethers.
