Which limit was addressed when creating universal astrolabes?

💡 Explanation

Planispheric astrolabes are latitude-specific, limiting their utility; the universal astrolabe addresses this through stereographic *projection*, deriving horizon lines applicable across latitudes. Therefore, navigators could use one instrument across geographic ranges, rather than switching by latitude because latitude projection differs.
