Reflecting telescope. Computer artwork showing the structure of a typical small reflecting telescope. A reflecting telescope is a type of optical telescope that collects light through a concave mirror that reflects it to a focal point,forming an image. The reflecting telescope was invented in the 17th century as an alternative to the refracting telescope,which,at that time,was a design that suffered from severe chromatic aberration. Most large-scale professional optical telescopes are now reflectors | |
