The most important reason to make telescopes large is light-collecting power. Larger telescopes can gather more light, allowing astronomers to observe fainter and more distant objects. This is particularly important for studying objects such as galaxies and quasars, which emit very little light and can only be observed with large telescopes. Atmospheric seeing, chromatic aberration, and magnification can all be improved with better telescope technology and design, but light-collecting power is the primary reason for making telescopes larger.
