October 6, 1999
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.)
Composite of 40 frames of Saturn with 2x barlow. You can see the ring is made of 2 distinct
pieces, but can't make out the Cassini division.
