Hi Eric;
If you check marked the "Post statistics for each movie to log file"
in the "Stacking Options..." window, then Astro IIDC will print off
statistics and other information on the processing of each movie into
a text file.
That includes the number of frames that were actually stacked (look
for "Stacked x out of x frames", noise levels (i.e Pixel Noise
Percentage: 1.506936) etc. etc.
HTH..

Hi guys,
Well, I've extracted about as much detail as I'm going to for this
composite. I have posted comparison images. On the left, is the
original 415 stacked images composite using 5 alignment points. The
right image is the same number of stacked images (415), but alignment
points were increased to 17. If you look carefully, there is definite
improvement, although mostly subtle:

I was never able to improve the interior craters because the
contrast wasn't enough to cause the software to align on for a stack.
I also ended up using a Win program called Iris to do the 17 points,
although the initial image on the left was aligned in IIDC. I think
the lack of contrast and noise levels caused IIDC to eliminate about
half of the stacked frames.
