WebMay 7, 2024 · Both of the latter telescopes use full-aperture corrector plates and hence don't use or need add-on sub-aperture corrective lenses. Because they both use spherical primaries, they are less sensitive to collimation errors than a straight (purely reflective) Newtonian (i.e., they usually don't need to be collimated as often).

WebMar 1, 2024 · Ritchey-Chretien Optics. The f/8 Astrograph is a Ritchey-Chretien telescope which is a variant of a Cassegrain. Unlike other Cassegrains that incorporate both mirrors and lenses, the RC uses hyperbolic mirrors and no lenses within the optical system. Like a Cassegrain, you can build an extremely compact tube while retaining a long focal length. WebDec 5, 2024 · The Omegon Pro RC 203/1624 provides a flat-field of view over a full-frame (36x24mm) camera sensor and requires no front corrector plate like similar-looking Schmidt-Cassegrain telescopes do. In addition, the low-expansion quartz crystal mirrors are fixed in place and avoid issues such as mirror flop that can spoil images from a Schmidt … Web12″ f/8 Carbon Fibre Truss Ritchey Chretien astrograph from GSO.
