  skos:definition "The Danjon astrolabe is a type of portable solstitial armillary, modified for stellar observation. Suspended by a small hook or eye, the instrument consisted initially of a single ring that hung in a vertical plane. Pivoted at the center of the ring was a rod equal in length to the ring diameter, carrying sights at either end. When aligned on a star or planet, an angular scale inscribed on the armillary ring showed the object's altitude.
