Where lots of frames can help is it effectivly does "superresolution" e.g. pixels moved a fraction of there width, and can technically allow them to act as if they are larger pixels, but it still needs contrast to make that process possible at the end, so your generally just making the image bigger, but not more detailed past dawes limit.
/ 1.80 = 0% contrast (Dawes Limit - Stacking Detail)
/ 1.48 = 9% contrast (Rayleighs Limit - Single Sub Detail)
/ 0.68 = 50% contrast (MTF50 - Apparent Sharpness)
/ 0.29 = 80% contrast (MTF80 - Imaging Times)

Ryan,
Do you have any of your planetary images to compare and demonstrate the details of your findings above ?
I’m most interested
Cheers
Martin
