Here is a link to Jupiter shot last night (3/30/04). Seeing was decent, but nothing to write home about. I found out that my Powermate 2.5x is giving me about F/22. I added a 1" extension before the barlow and it raised my efl to F/23. That is how I shot this image. I enlarged the final image 25% and there is little image drop-off. The weather here is supposed to get unsettled by the weekend, but we'll do what we can.

Hey Paul, how do you determine your f-ratio? I have a 3X barlow that I wonder about.

Paul,

Thank you for posting your excellent image of Jupiter. I too have noted the angulating rift within the South Equatorial Belt (SEB). Please keep up the good work imaging the planets.
