What is the maximum height that Rigel will attain on any given night?
To answer this question, rotate the rete until Rigel is on the meridian (see below). Rigel is a little more than halfway between the 30 and 40 degree almucantars (the scale is written on the meridian.) A good estimate might be 37 degrees above the horizon. Thus Rigel will never be more than 37 degrees above the horizon in Stevens Point, Wisconsin.
