Jon, I can't seem to figure out how to stack images in Picture Window that 
I have aligned in Regi Star, if that is possible.

As I said, I'm a novice.  Actually I compared several variations of stacked 
images just to see if one could gain any benefit from stacking that 
many.  There was a noticeable difference between 3 image stacks and 4 image 
stacks.  I went with the 7 image stack with the assumption that there would 
be yet some further gain in the S/N ratio because I wanted to sharpen up 
the image a bit using the unsharp mask in Photoshop.
