← HistoryWhich visual distortion occurs when using astrolabes improperly calibrated?
A)Elliptical celestial sphere projection✓
B)Spherical aberration of star positions
C)Refraction index of lunar cycles
D)Aberrant scattering of reflected intensity
💡 Explanation
An astrolabe's inaccurate grid creates an elliptical projection rather than correct spatial coordinates. This occurs because errors compound transformations, therefore distortion arises rather than accurate positions due to angular misalignment.
