Advantages of a Ritchey-Chretien Telescope: Disadvantages of a Ritchey-Chretien Telescope: The most common reflector telescope we use today was invented by Isaac Newton, which is why you'll hear this type of telescope also referred to as a Newtonian reflector. Wearing glasses keeps your eye further away from the telescope eyepiece, and if the eyepiece does not have good eye relief - the distance from the lens to where the image comes to focus - you may not be able to see the object very well, if at all. Since the Ritchey-Chretien telescope uses mirrors to gather light it is technically a reflector, but unlike the more common Newtonian, the RC - short for Ritchey-Chretien - has a Cassegrain configuration. On the high end, RCs are more expensive because they use a hyperbolic primary mirror design. After all, a telescope is often a one-time purchase, and unless we do some targeted research, we are not apt to see advertisements for telescopes like we do cars or washing machines. We will go into each of the questions in greater detail further down the page, so scroll down if you need more information. These are the largest optical/IR telescopes in the world.
