Electronics aside, assuming the availability of accurate time, along with whichever tables the individual might choose to use for sight reduction, how else is one to obtain an accurate number for the altitude of celestial bodies?
One could use a protractor along with a piece of string and a weight of some sort and get an altitude number for a celestial body, but we then come face to face with ""accuracy"" of some desired level. This can be obtained with a sextant, and for many years has served well. As to doing this sort of exercise without a sextant, what might one use instead? I cannot, off hand, think of a substitute.
