Which challenge limited astrolabe positional accuracy, compromising celestial prediction?

💡 Explanation

Thermal expansion causes astrolabe metal components to subtly change shape with temperature, therefore decreasing measurement accuracy, because differential expansion causes distortion rather than maintaining proportions, thus affecting alignments.
