Which risk increases when setting an astrolabe's alidade improperly?

A)Inaccurate star altitude measurements
B)Parallax error becomes negligible
C)Declination calculations remain precise
D)Instrument edge corrosion accelerates quickly

💡 Explanation

Incorrect alidade alignment introduces angular error because the observer's line of sight is skewed relative to the observed celestial body through angular MISREADING, therefore altitude is wrong rather than declination remaining correct under misalignment.
