Hi David. Don't worry about RA readings. They don't come into the equation at all. Just focus on the Dec readings.
You adjust elevation by selecting a star around 15 deg - 20 deg above the horizon at Dec 0 deg (East or West). And you adjust Azimuth using a star close to the Meridian at Dec 0 deg. You can easily allow +/- 5 deg in either side of 0 deg Dec. The meridian star and the horizon star can be +/- 5 deg also. The closer the better but not essential.
You must be a long way out for the star to drift of the CCD that quickly. Do you use a compass to do an initial rough alignment? Try keeping the star on the screen using your keypad while you make adjustments. Once you get the hang of doing that K3, will make your alignment so much quicker.
