← HistoryWhich mechanical consequence arises when an astrolabe's alidade is misaligned with the rete during celestial observation?
A)Inaccurate altitude measurements of stars✓
B)Distorted representation of ecliptic plane
C)Biased calculation of planetary positions
D)Incorrect determination of local solar time
💡 Explanation
When the alidade and rete are misaligned, parallax errors are introduced because the angular readings taken from the alidade do not accurately correspond to the intended celestial object on the rete, leading to skewed altitude recordings. Therefore inaccurate positional measurements result, rather than a distorted ecliptic, biased planetary positions, or localized time, all of which depend from different instrument errors.
