A 16th century nautical device that determined latitude by taking the altitude of the sun, moon and stars, thereby helping with navigation. Team 5 of Series 6 retrieved an astrolabe from Ariadne's lair for Captain Nemanor of the Cloudwalker, who then helped them proceed.

Not to be confused with an Astro Farm.
