Without a telescope or guiding. Canon 40D and Canon 400mm 5.6 lens @ 1", f/5.6, iso1600, cropped. Taken at 8:16pm, Chicago, March 15th. I shot some others with the 1.4x TC, but the shorter exposure without the TC had a little less drift and the same IQ.

I think there are at least three moons visible in the pic, along the equator. Io, Europa, Ganymede and Callisto are likely candidates. Anyone know which ones I got in the pic, and in what order?

David,
You most likely have Ganymede, Callisto, Io, and Europa in order from the top. Unfortunately with Jupiter, you have to blow out the planet to get the moons. If you wanted planet detail in your image, you would have to expose for a much shorter time, something in the range of 1/30 second. You will lose any moons. To have both, you would have to make a composite image.
