Not sure if something like this could be done with the Polarie?

Jo maybe a slight variation on the theme - since the Polarie does not have a x2 tracking rate (although it does have a 1/2 rate). Perhaps 1 minute with 1/2 speed guiding, 4 minutes at full speed and 5 minutes unguided? What do you think?
