Astrolabe Advanced

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. I have included a zip file containing plates for 30-70N latitude. This is more advanced version of the basic astrolabe posted here (https://www.thingiverse.com/thing:3657530).
