Which optical consequence arises when improperly aligning astrolabe alidade sighting vanes?

💡 Explanation

Parallax causes apparent shifts in positions, because misaligned alidade sighting vanes introduce angular displacement. Therefore, measurements become inaccurate, rather than creating chromatic aberration from dispersion or resolving interference patterns from diffraction.
