← HistoryWhich lunar observation error increases when an astrolabe's alidade bends?
A)Increased measured star declination
B)Erroneous lunar phase calculation✓
C)Inaccurate time-of-day indication
D)Magnified solar eclipses foreshortening
💡 Explanation
Erroneous lunar phases result when an alidade is bent because parallax compensation depends upon angular accuracy; therefore lunar phase calculations will be inaccurate, rather than altering star positions significantly as that involves separate scales.
