Hi doodlebun;

Thanks for posting your processing flow.

One thing you can do to save some time and speed up the processing is to use one of the Color channels (Red, Green or Blue) instead of Monochrome. Even thought your using a monochrome camera, QuickTime delivers the image as ARGB32 with Red == Green == Blue for color intensity (basically it populates the R G B with your single Monochrome color). If you choose Monochrome, then Astro IIDC will convert the R G B colors to monochrome, which involves 3 multiplies and 3 adds per pixel to calculate it. If you use Red (or Green or Blue) then Astro IIDC will just extract  the Red (or Green or Blue)  pixels without doing the additional conversion work.

The only reason to use Monochrome is to help with noise suppression for RGB color movies.

Hope that helps..

to some trouble to show the creation steps leading to the final RGB image of Jupiter shown 

on my blog page. Comments appreciated of course.
