Here is an image of Saturn and its 8 largest satellites, all captured using a single exposure setting on a stacked video. Saturn is overexposed (with ring structure evident in the diffraction spikes). Canon EOS 600D, 12" SkyWatcher Dobsonian, ISO 6400, 4fps, 1/4sec exposures.
From faintest to brightest:
Hyperion Mag 14.9
Mimas Mag 13.3
Enceladus Mag 12.3
Iapetus Mag 11.5
Dione Mag 10.9
Tethys mag 10.7
Rhea Mag 10.1
Titan Mag 8.9
The stars are 12/13th magnitude
My previous attempts have captured 7 satellites max, so I'm happy with this.
Janus is as bright as Hyperion but too close to the planet and the next brightest is Phoebe at Mag 16.9 currently about half a degree away, so this is probably as good as it will get for my set up.
Thanks for looking,
Tom
