Ben Reese it's actually pretty simple (hopefully if I did my job correctly)... The earth rotates and it's axis of rotation just happens to point towards the north star(Polaris) or pretty damn close. You point the hinge towards that star keeping the open end of the hinge towards the East. As the the stepper motor turns the threaded rod the hinge opens at the same rate of the stars moving across the sky keeping the camera pointed at it. As for the rate, smarter people than me have done the math ,but basically the way it's set up 1RPM should be about right. The hard part for me is going to be actually pointing that hinge at the north star. If I don't get that right the rest won't matter. Hopefully the sky's clear up soon and I'll be able to test it out.
