move the guide star approximately the width of the screen. If you do see the magenta circle, you should move the guide
star to the circle, like this:
After moving the guide star, click Drift to take another measurement. Before you click Drift, it's OK to nudge the mount to
re-center the star, or to find a different star, or to get back closer to the meridian. Also, you can choose your own guide
star by clicking on it, or just let PHD2 choose. After a short time drifting, you will have another Dec trend line. Did it get
better (closer to horizontal) or worse (away from horizontal)? Make a note to yourself in the "Azimuth adjustment notes"
area of describing how you adjusted azimuth, and which direction the Dec slope moved. You can use this information next
time you drift align so you do not have to guess which way to make the azimuth adjustment. For example, with my setup,
turning the azimuth knob clockwise makes the slope go down. Having the note there reminds me that I need to turn the
azimuth knob counter-clockwise to make the slope go up. Repeat the measurement and adjustment of the mount until
you achieve a good flat horizontal dec trend line, like this:
