I've changed my processing scheme a little bit. Now I test the sharpness of a frame by using its power spectrum to determine high frequency content instead of the previous RMS pixel/neighbor difference. It agrees much better with what I "eyeball."

Also, I've stopped unsharp masking images and instead am using a method of my own which involves using the image's Fourier transform to emphasize certain spatial frequencies over others. I'll write it up in the processing section when I get a chance.
Good seeing today (and focus, too.)
