Not the best Jupiter, but *my best so far

We had good seeing in Melbourne tonight (jetstream dead still!), but I still have some tube current issues to deal with, even with the fan. A baffle is the next thing, I guess, or a side fan to break up the envelope of slightly warmer air coming off the mirror. It had been cooling all day as it's stored outside, but still chasing that temperature differential once the sun goes down, I guess.

I used EP projection (3.5mm Pentax XW)
16" GSO Dob (no tracking, just letting the planet drift through frame)
Canon 5dMk4 in 4K mode, 1/200, ISO3200
PIPP, Registax and Photoshop

I was pretty happy with what I got considering it was EP projection on a scope that is not tracking. I may be able to improve it with different approaches to the data.
