I used winjupos to assemble a full rotation of the planet. The raw input was obtained during two nights.
Seeing, not handled by stacking
One might think that a planetary image, through stacking, lacks major distortions. Nope, those distortions are still there. Below are two successive videos, 1:40 each. ASI 224MC, TSO ADC, N250/1200, HEQ5

ASI 224MC, TS Optics ADC, Barlow, N 250/1200, HEQ5 – the usual.

All with the usual gear: ASI 224MC, TS Optics ADC, Barlow, N 250/1200, HEQ5

Jupiter – 2015-02-12, that great night
It was a great night. The best seeing and conditions I have ever recorded a planet, to date. And it was when Io cast its shadow onto Ganymede, making the moon go partially dark.

Jupiter-nostalgia, 2015-02-12
Perhaps the best seeing of my amateur astronomer life, Jupiter very high up on the sky, and Io eclipsing the Sun from Ganymede. With a … webcam, N 150/750 on an EQ3. Remember, jovial dance.
Jupiter’s family 2019-05-11
During this morning, Ganymede played hide and seek, emerging from Jupiter’s shadow, just to disappear again, behind Jupiter’s limb. I used my usual planetary setup, ASI 224MC, TS Optics ADC, Barlow, N 250/1200, HEQ5 installed in my balconic-balcanic improvised observatory. The seeing was, this time, good to very good, with Saturn’s Cassini gap visible on the live view images, and Jupiter GRS also obvious on the live view. It’s mostly not the case, I must add. The moons are Io, Ganymede and Europa. Ganymede was part of the original recording (it was in the ROI selected for the planet), while Io and Europa are composited onto the image.
Saturn’s family, 2019-05-09
I dug out Saturn’s moons, from a longer expo series of images, and composited it with the lucky imaged Saturn. Below’s the process. There is also a random star photobombing the frame.
