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 mo-
ved. 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:
