Which optical consequence limits the astrolabe's accuracy at steeper viewing angles?

💡 Explanation

Increased spherical aberration reduces observation accuracy because rays passing through lens edges focus at different points rather than a perfect point; therefore, image quality and resolution reduce considerably at steep angles, rather than merely affecting atmospheric refraction uniformly.
