Which optical consequence arises during observations through low-quality astrolabe alidades?

💡 Explanation

Chromatic aberration blurs star images because shorter wavelengths refract more strongly due to dispersion caused by imperfect early lenses; therefore, different colors focus at different points, rather than creating a sharp image like modern optics would provide.
