Found out I had a collimation issue and fixed it.
Wanted to try it out on Saturn. While waiting for the scope to cool down,
I checked where the moons were and saw that a Tethys transit was in progress,
so I started capturing 20 mins earlier than I had planned.
This is a 3 video derotation- I tried derotating all 7 but lost the moon somehow.
It would make a good animation if I knew how to do them properly.

I thought I was finished capturing, but as I watched Saturn drift off the screen
I noticed a small dot following which was Titan.
So I changed the cut out box size and did another 3 videos, this from just
one of them with both Tethys and Titan:

Nicely done.  That assymetric ghosting on Saturn's disk and Titan (7 o'clock) suggests that you still didn't quite get your collimation dialed in all the way.
