Which mechanism limited the early accuracy of observations using medieval Islamic astrolabes for celestial navigation?

💡 Explanation

When an astrolabe was used, manufacturing imprecision caused parallax error because small variations in component placement shifted the perceived positions of celestial objects relative to the observer's location. Therefore, less accurate navigation resulted rather than refraction which although relevant, could not be compensated and/or incorrect cosmic framework and inaccurate timeline measurement.
