In an equatorial telescope mounting located in California the axis to which the sidereal drive is attached must point toward the horizon or zenith or north celestial pole or ecliptic?
PleaseandThankYou
East to west.
First answer by N4CUZ1.
To clarify, the sidereal day is the time it takes the earth to complete one rotation. i.e. One Day. So, depending on your telescopes mounting, equatorial primarily, the drive should rotate in the opposite direction of the earth's rotation to maintain an object in your view finder. Hence, west to east.
Cheers.

∙ 13y agoSince the motion of any object in the sky centers around the Celestial Poles, and the
purpose of the telescope's sidereal drive is to cancel that motion so that the object
being observed appears motionless, the sidereal drive's axis must point toward the
Celestial Pole. In California, the one on which to align your equatorial mount is the North
Celestial Pole, since that's the one that's visible from anywhere in the northern Hemisphere.
