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 ... WebJan 7, 2024 · Short focal length telescopes – especially Newtonian reflectors – exacerbate this problem, but field curvature is present in most telescopes to some extent. The exception to this is with refractors employing an optical design known as a ‘Petzval’, in which there are four lens elements, the front pair correcting chromatic aberration and the rear pair …
WebFeb 29, 2024 · So an 8" f/6 Newtonian has curved field with a radius of 1200mm, while an 8" f/4 has a field curvature radius of 800mm. Therefore the faster (f/4) telescope has greater field curvature (a more strongly curved field). In more complex optical systems, there is often not a direct relationship between focal length or focal ratio and WebWhether you are new to astro-imaging or a seasoned expert, we have you covered.
