What did Galileo see when he pointed his telescope at Jupiter?

So I was futzing tonight with the ZWO ASI 224 and I tried something a little counter-intuitive. I asked myself "how well would the 224 image Jupiter through the Galileoscope"? The Galileoscope has, at best, jerky focusing, a 500mm focal length, rudimentary gunsight aligning, no tracking and uses a camera tripod as a stand. And the seeing tonight is listed as "poor" with lots of clouds. I was able to get one run in. It took about 20 minutes to set everything up and get the camera in reasonable focus so that I could ID the cloud bands of Jupiter on my monitor. I took 2000 frames and kept the best 30%. The results are below.


Even with my ham fisted editing it's still way better, I suspect, than what Galileo would have seen. :)
