Which observational error increases when selecting distant stars on an historical astrolabe?

💡 Explanation

Precise star selection on historical astrolabes demands careful leveling to minimize observational error. Because *instrument alignment* crucially limits angular accuracy, therefore greater care focusing on stars farther from the zenith, rather than relying on inherent minimal refraction at the lens.
