This f6.3 Focal Reducer / Corrector design is a four-element, fully multicoated focal reducer and field flattener. It effectively reduces the focal length of an f10 telescope to f6.3.

It has an SC-thread (Schmidt-Cassegrain thread) at both ends (female and male threads), so can be screwed directly into a Schmidt-Cassegrain or similar telescope. It would work with most Schmidt-Cassegrain telescopes from Meade and Celestron, with Ritchey-Chretien telescopes from Meade and Maksutov-Cassegrain telescopes from SkyWatcher and Intes Micro.



  • F6.3 reducer/corrector (field flattener)
  • Transparent plastic holder for the reducer/corrector


  • Fully Multi-Coated Four-Element Optics
  • High quality metal housing
  • Rubber coating on the reducer's housing
  • Compatible with standard SCT threads
