During the Golden Age, which visual distortion affects early telescope designs that use spherical lenses rather than parabolic mirrors?

💡 Explanation

Spherical aberration occurs because spherical lenses fail to focus parallel rays to a single point, therefore blurring images; rather than chromatic aberration which separates colors, thus this becomes a geometric distortion problem.
