Chromatic aberration is a common issue with refracting telescopes due to the different wavelengths of light refracting at slightly different angles when passing through the lens. A small-diameter refracting telescope would also have a low light-gathering power, making it the most likely choice. Reflecting telescopes, on the other hand, use mirrors instead of lenses to gather and focus light, and are not as susceptible to chromatic aberration. Large-diameter telescopes would have greater light-gathering power than small-diameter telescopes. Infrared telescopes use a different wavelength of light and are not affected by chromatic aberration, but they generally have specialized uses and are not necessarily known for low light-gathering power.
