During the Islamic Golden Age, which optical effect limited the angular resolution of astronomical observations using early refractors?

💡 Explanation

When light passes through a single lens, chromatic aberration arises, causing different wavelengths to focus at different points and blurring the image because of variable refraction. Therefore, chromatic aberration degrades the angular resolution, rather than spherical aberration, diffraction, and scintillation, arising from different lens imperfections or atmospheric conditions.
