reflecting telescope
A telescope that uses mirrors to magnify and focus an image onto an eyepiece or other device, such as an array of charge-coupled devices. Its main advantage is that, unlike a refracting telescope, it doesn't suffer from chromatic aberration. The main designs of reflector in use today are the Newtonian, Cassegrain, and Ritchey-Chrétien telescopes.
