Hi Jim,

A very fine result - though I think not at the limit of your 8" aperture... sorry, you can't retire yet! 8^)

I was disappointed in the seeing conditions last night after seeing the glorious forecast on CSC, but I did enjoy the rotation of the GRS and the approach of Europa and Ganymede through my 10" scope and binoviewer.

Thanks for sharing,

Alan

Last night the seeing was very nearly perfect and I was able to capture the dual transit of Ganymede & Europa from 11 PM until 2 AM by taking an image every 20 minutes. Jupiter shows lots of good detail at I suspect the limit of my 8 inch aperture and its 30 degree altitude and even Ganymede is visible as it travels across the disc of Jupiter.

I am now officially retired from imaging Jupiter for 2009.
