Happy Mole Day! Here is the results of 2 1000frame vids captured through my 203mm f/4.9 Orion reflector and 2x Barlow. Each video was captured in 5x crop mode in BYEos and stacked in registax6. The best 200 frames was picked.
I might try restacking these using a different reference frame in an effort to tease out more detail in the clouds.
Theoretically, you could use a 5x barlow and go for f 30 if your seeing is really nice. My point is that you could get more detail by magnifying image and capturing more frames. An f4.9 newtonian reflector is pretty fast for planet imaging.
