Star Drift Method for Polar Alignment of Equatorial Mounts

I explain how to polar align an equatorial mount using the star drift method. This is the spoken text: This video illustrates the principle of the star drift method for polar alignment of an equatorial mount. A rough alignment is first performed by pointing the RA axis of the mount towards Polaris. The up-and-down tilt of the RA axis is called the altitude adjustment and the left-right adjustment [is called] the azimuth adjustment. We will illustrate here the azimuth adjustment for the northern hemispher
