Which error is magnified when using an astrolabe with a small diameter to determine distant star azimuth?

A)Parallax error from near objects
B)Spherical aberration in alidade sight
C)Mechanical tolerance in degree markings
D)Atmospheric refraction on horizon

💡 Explanation

When astrolabe diameter is small, the mechanical tolerance in degree markings corresponds to a larger angular error, because the same physical distance represents a coarser angle. Therefore mechanical tolerance dominates, rather than parallax, aberration or refraction, minimized under different conditions.
