Nope, mine is a stack of frames taken from a video recording. There is free software out there that will analyze video, then stack the best % of frames into a single image. In my case since I was using a mono camera with filters, I took three 24 second videos (one for each RGB filter). Stacked the best 50% for each filter. Then combined them in editing software to make the rgb image.
There is free software that will do this. I used a program called AutoStakkert. An other one is called registax. They both stack video. Then you would use a photo editing program for post processing.. like sharpening, boosting saturation, pulling out faint details, etc. For stacking single exposures, DeepSkyStacker is another free program that I've used for deep sky objects (Nebuals, Galaxies, etc).
You could do the same with your camera.. except you just need one video file. Jupiter's rotation is pretty fast so you'll want to keep the recording under 2 mins.
The moons are probably there in the 1/30th image. With editing software you can mask Jupiter to protect it, then boost the brightness by stretching the histogram to pull the moons out.
When I'm not pulling the trigger I'm out taking pictures of the night sky
