text: A catadioptric telescope is an optical system that is optimized for producing images of objects at an infinite distance, and which incorporates both refractive type optics (lenses) and reflective optics (mirrors).
text: After the initial alignment, their optical system is more resistant to misalignment than the reflector telescopes.
text: There are not reflections or interruption of the light path, there is near permanent optical alignment, minimum maintenance, and long focal ratios can mean the use of longer focus, simpler and eyepieces, Refractor telescopes are rugged after the initial alignment their optical system is more resistant to misalignment than the reflector telescopes.
text: A telescope consists of an optical system (the lenses and/or mirrors) and hardware components to hold the optical system in place and allow it to be maneuvered and focused.
