Chromatic aberration is a problem specific to refracting telescopes and is caused by the inability of the lens to focus all colors of light to the same point. A small diameter objective would exacerbate this issue. In addition, a low light-gathering power suggests that the telescope does not have a large objective lens or mirror to collect light, which could be the case for a small diameter refracting telescope.
