Analysis of GSO Ritchey-Chrétien's Baffling Issues (resold under Orion, TS-Optics, ...)
Ritchey-Chrétien telescopes by GSO, Guan Sheng Optical, are a popular option in the medium price range. They are resold by various retailers, such as Teleskop-Express/Teleskop-Service, Orion, iOptron, Astro-Tech, Apertura, TPO, … . They unfortunately suffer from an optical design problem which limits their use. With the primary mirror baffling issue corrected, they are good telescopes with excellent value (I use an RC myself in my own observatory), but the baffling design flaw introduces significant problems “as-purchased”, especially during bright moonlight.
