Across the medieval Islamic world, which instrumental constraint limited astrolabe accuracy during astronomical observations?

💡 Explanation

During crafting, manual engraving processes led to unavoidable graduation errors on the astrolabe's limb, directly impacting angular precision because each division marks a unit of angular measure. Therefore, graduation inaccuracies constrain observation, rather than slippage, corrosion, or thermal which require different manufacturing weaknesses and environmental conditions.
