Almost all large research-grade astronomical telescopes such as space telescopes and spacecraft imaging devices are reflectors because mirrors have some advantages over lenses in terms of cost and the absence of chromatic aberration. However, like any other optical instrument, reflecting telescopes do not produce perfect images, though they do utilise parabolic shaped mirrors or correcting lenses to reduce these imperfections. Some users may also find reflecting telescopes harder to maintain due to their open tube designs.
Wondering what Newtonian reflector telescopes are? They are actually named after Isaac Newton, who has been widely credited for building the first ever reflecting telescope in 1668. The Newtonian reflector telescopes on our website refer to the telescope's optical configuration that he popularised, although many advancements have been made since the 1700s that have resulted in today's Newtonian telescope.
