Increasing the diameter of a telescope increases its light-gathering power, allowing it to collect more light from faint objects, and increases its resolving power, enabling it to see finer details by improving its resolution. However, the magnifying power of a telescope is primarily determined by the eyepiece used, not the diameter of the telescope. Chromatic aberration is more related to the material and design of the lenses rather than the diameter of the telescope, especially in the context of reflecting telescopes which use mirrors.
