Which limitation to resolution occurred in medieval astrolabes focusing on distant landmarks?

💡 Explanation

Medieval astrolabes used a pinhole for sighting because diffraction limits resolution based on wavelength and aperture size; therefore increased distance blurs the image, rather than chromatic aberration (requiring lenses) or quantum/polarization effects.
