Astrolabe Basic

The astrolabe is a multi-function calculator of the Real Old school. It can help you find the time, day or night, quite accurately. It can do basic surveying, determining distance, depth and height. This is a working model of a basic, fairly common set of options. I have included a zip file containing plates for 05-70N latitude.
