← HistoryWhich outcome occurs when astrolabe plate misalignment introduces parallax error during observations?
A)Incorrect star position measurements✓
B)Inaccurate shadow length calculations
C)Reversed celestial sphere projection
D)Fractured instrument alidade component
💡 Explanation
When an astrolabe plate is misaligned, parallax error occurs because lines of sight don't accurately represent the celestial coordinates, skewing angle measurements in angular measurements. Therefore, incorrect star position measurements result, rather than shadow length, celestial sphere projection, or structural failures, requiring alternative mechanisms.
