Which limitation appears when an early astrolabe's alidade corrodes?

💡 Explanation

Corrosion of the alidade degrades its alignment, preventing accurate angular measurements because parallax error increases. Therefore, celestial angles become skewed, rather than affecting time calculations or larger mechanical failures in the rete’s degree alignment itself.
