Not at all familiar with the camera you are using. 6FPS is painfully slow though, you should still be looking to capture more than 200 frames, as you do at least 180 second imaging runs (1000+) frames. the imaging scale for Jupiter looks too big to me, which would focusing even harder as well. Saturn looks a bit overexposed.
As for focusing i follow the same process every time. Firstly i don't stand to close to the monitor, i then experiment inwards and outwards slowly making smaller movements in each direction, until i think i am somewhere close to the point of focus. I then watch the image for a period of time to see what it looks like at the better moments, as the focus tends to come and go depending on the seeing conditions on the night.
