Gee those explanations confused me and I used circles on my last scope. If you have your circle aligned to true north - being zero, then turning it Clockwise reaches 90 degrees after a quarter turn and your now pointing East. South is at 180 degrees, and West is at 270 as you continue around clockwise. My magnetic declination was 12.3 degrees here near Newcastle. It helps yo have a good compass that has a rotating bezel so that you can set it to point to True North when the needle is pointing at magnetic. Maybe this is easier if your shown how to do it.
My degree and altitude co-ordinates always work with the various sky software Alt-Azimuth co-ordinates. So if 0 is True North the Azimuth numbers go up as you rotate the scope clockwise - its that simple.
