Modern Nautical Astrolabe

A "Nautical Astrolabe", as some might name. The name "Astrolabe" relates to an ancient cartographic instrument more similar to a dish with a stick... It's function was simple "how to locate yourself in the map, with just the stars". In this case, I made the modern version of this instrument ("Modern", when a thing is from 1750, and compared with 500 B.C thing...), rightfully name "Nautical sectant". When you look at it from the spyglass, you will see two images, one from below, and one from above. Here, you try to aling the horizont with the sun, in a way the sun almost touch the sea. Knowing the time and some trigonometry, you will know you location, or if you know you location, you will know the time. Complex but simple. I hope you enjoy.
