Jupiter with G11...is this the best I could do?

I tried to capture Jupiter with my G11....Optical Zoom all the way, ISO 400, 4.5 at 4 seconds. Manual Focus to 1 tick shy of Infinity, IS off, on tripod

This is a 100% crop and the original below.

I see that I got the moons, but Jupiter is just a white blob.

I think these are great, but curious if there was something I could do with the G11 to get this shot even better. Without Stacking.

Straight from the camera and only a crop.

Cropped

You've got Jupiter way over-exposed; it's next to impossible to get both the planet and the moons to both be well exposed. Try something like 1/30 to 1/60 ss to get the planet, but you'll lose the moons.

Jupiter is a white blob because it's over exposed. Speed up the shutter some. To get the moons and jupiter 2 exposures is needed (one for the moons and one for jupiter) then combine them in photoshop. I know you did say without stacking but i think this is the only way...
