Which effect limits astrolabe accuracy when sighting distant objects?

💡 Explanation

Diffraction limits resolution because light waves bend around the edges of the alidade sighting holes in the astrolabe, resulting in a blurred, larger spot size, therefore, precision decreases, rather than merely distorting the image.
