Astrolabe (EM)

__NOTOC__
The historical astrolabe was a device used to determine the astron of the sun, the moon, and other celestial objects. Originally, the navigator of a sea-going vessel would locate a relatively stationary stellar object (the North Star, for instance) and find its position. From that reading, the navigator would be able to calculate the approximate latitude of the ship. Since most sea travel was done on an east-to-west axis from common ports, the navigator rarely needed to know the longitude. Simply knowing that the ship was three days out of home port, the navigator would know the approximate number of days left in the voyage. The navigator did need to know how far north or south he or she was from the destination.
A magical astrolabe allows a navigator to know exactly where the ship is, both in longitude and latitude, without having to make exact measurements and precise calculations.
