Which lunar observation error increases with astrolabe 's declination-based angular measurement?

A)Parallax error is magnified
B)Instrument mounting instability forms
C)Tidal force computation fails
D)Alidade bending stress intensifies

💡 Explanation

Increased declination amplifies parallax error measurement because of spherical projection inaccuracies in the astrolabe's stereographic projection, increasing perceived displacement. Therefore, parallax increases, rather than issues in alidade stress; these are separate instrument errors.
