← HistoryWhich outcome occurs when aligning an astrolabe vertically?
A)Visual zenith is more accurately found✓
B)Parallax error of starts increases
C)Solar altitude measurements become imprecise
D)Declination of planetary objects is wrong
💡 Explanation
Precise vertical alignment minimizes errors due to the mechanical properties of the device; therefore, accurate zenith alignment increases, rather than misalign planets because gravity defines the reference, unlike horizontal adjustments using fluid or other methods.
