  1. The sky was mostly clear to partly cloudy and I was fortunate to get a window between 9 and 10 p.m. EST to capture the double shadow transit here from the States. Ganymede's shadow is the larger of the two on the bottom left (moving toward bottom center) and Europa's is on the lower right, approaching the limb. The moons themselves were as follows: Io to the upper left, Europa lower right, and Ganymede bottom right (farthest out). The GRS was also visible making it a pretty spectacular apparition!

    Thanks Reggie, however, I've had a couple of very experience and highly respected planetary imagers review my image and they are not confident to call it, so as @Space Cowboy said, it's tantalising, but maybe not a done deal. Regarding minimum aperture, I'm not sure. @Kon has no issue capturing the polar hood with his 8" dob, but the only images of the rings that I have seen are from 16" and 18" scopes. I think that I should be able to get them with my 14" in excellent seeing, but until I do, then I guess the jury is still out.

    Thanks for the aperture info, Geof. And as long as the jury is still out, we can at least enjoy the possibility of their being the actual rings :)
