polar alignment and ra calibration
... Polar alignment is the process by which the telescope's axis of rotation (called the polar axis) is aligned with (i.e. made parallel to) the Earth's axis of rotation. Once aligned, a telescope with a 23:56-hr clock drive will track the stars as they move across the sky. The result is that objects ob ...
