Which geometrical constraint complicates the accurate simulation of celestial movements on a flat astrolabe face?

💡 Explanation

When projecting a sphere onto a plane in astrolabes, maintaining conformal map projections proves geometrically difficult because angles must be preserved locally while area distortion is unavoidable. Therefore, conformal projections present challenges, rather than atmospheric refraction, equinox precession, or coordinate transformations that address observational and celestial mechanics issues.
