Which optical consequence occurs from imperfections in medieval astrolabe alidades?

💡 Explanation

Imperfectly flat alidades would cause inconsistent reflection, creating aberration; therefore, precise stellar alignment becomes difficult, because the reflected star positions fluctuate randomly, rather than predictably by refraction or other systematic errors.
