Great stuff, I've seen it a few times.
The view of Orion doing a circumpolar type rotation puzzles me.
I first thought, where in the world would you see Orion's belt
do that, seeing as how the belt is nearly Declination zero?
If you were at the north pole, wouldn't Orion sort of just circle the
horizon 360 degrees? Where do you get circiumpolar type time
lapse of the belt? Or rather, how fat north would you have to
go to see this, it's obviously a genuine time lapse...
