It was shot at about 350UT (March 29) with the 10" at F/32. I resized the image by 1.2x during Registax processing. The moon, Rhea, is seen at about 2 o'clock. A bright spot can be seen in the middle of the disk just under the shadow of the rings.

I'd like to have half of the seeing you had, for me that would be great seeing Yesterday night I tried with the 6" Mak @F36, but the seeing was aprox. 0.1 / 7, very blurry result and the blue channel straight into the waist bin Oh well, the next time ......

Chris Go's recent challenge has me thinking differently. Or maybe just my eyes...

I don't think I adjusted my processing procedure on this image from normal, but I have made a major adjustment on my capture process. With the Skynyx and LuCam Recorder, I would typically set contrast at 1.2-1.4. While it gave better disk detail, it took away from the overall picture. Now I set contrast no higher than 1.05, normally leave it at 1.0. Now I get the crepe ring and better images of moons. Also, I went from 17fps to 10 fps so I can increase exposure time. This allows me to get about 50-60% on the brightness rather than the 30-40% before. Always something to try, huh? **grin** Paul Post Extras:       Pages: 1
