Editing Polar Alignment (section)

==== Altitude adjustment ====
Once azimuth movement is minimized or stopped, point the telescope toward a star in the eastern sky (the western sky will work too, just reverse the directions given here). As with the azimuth adjustment if the R/A axis is not sufficiently angled the star will appear to move through the field of view.

If the star moves '''south''' in our field of view the R/A axis is pointed too '''low'''. As with the azimuth adjustment the path of the star moves according to the earth's rotational axis. In the image below you can see how the path of the star (black) moves through our field of view (red). Adjust the mount to increase the angle of the R/A axis until movement slows or stops.

If the star moves '''north''' in our field of view the R/A axis is pointed too '''high'''. Adjust accordingly until movement stops.

Once alignment is dead on the mount will be able to track the star without it moving in the field of view. See in the image below how the earth's rotational axis and our mount's R/A axis are aligned, therefore the tracking can follow the star.

And now we're hopefully done with drift aligning! If you're unable to get movement to stop completely in your first run through, you can repeat the process several times until you're happy with it.
