Hi all,

I had some decent seeing on the evening of March 28 and got the following Saturn image. 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.

Now that's a really nice image Paul, lot's of detail
and very sharp.
I'd like to have half of the seeing you had, for me
that would be great seeing :crazy:
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 :bawling:
Oh well, the next time ......

Well done! Did you change your processing routine at all?? Chris Go's recent challenge has me thinking differently. Or maybe just my eyes...

Great work,

Thanks!! 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**
