Here
            is a comparison of the Planet Saturn in both visible light and
            ultra violet wavelengths. The upper image was a filtered tri
            color RGB sequence, each color a stack of the best of 1000 frames.
            Seeing was average, and varied from 5 to 10 arcseconds. The blues
            in the polar regions was very interesting. The lower frame was
            taken with the schuler UV filter, isolating the methane band.
            Not much for belt detail. The UV filtered exposures were 100x
            longer than the RGB images!
