WebA Ritchey–Chrétien telescope ( RCT or simply RC) is a specialized variant of the Cassegrain telescope that has a hyperbolic primary mirror and a hyperbolic secondary mirror designed to eliminate off-axis optical errors ( coma ). The RCT has a wider field of view free of optical errors compared to a more traditional reflecting telescope ... WebNewtonian is a good instrument, but probably it is harder to handle (collimation and balancing above all). Also the edge HD is a good instrument, but I'm not sure that the …
WebCollimation and coma in a Newtonian telescope By far the most common reason for non-round stars in a Newtonian telescope is poor collimation. This produces an optical aberration called coma. Some examples of the appearance of coma in images can be found in the diagram to the right. Keep in mind that coma may be combined with other optical … WebFeb 29, 2024 · Ritchey-Chrétien is commonly abbreviated RC. How Ritchey-Chrétiens Work RCs are a type of Cassegrain telescope, meaning they use a folded optical design like the more familiar Schmidt-Cassegrain telescopes (SCTs). However, they are an all-reflective system, using only mirrors and no lenses. Instead of the mirror being supported on the ...
