• Reducer shortens the effective focal length of Schmidt-Cassegrain telescope optical system by 37%
• Converts f/10 optical system to faster f/6.3 for a significantly wider field of view
• Shortens exposure times for astrophotography by 3 times
• Four-element, fully multi-coated optical design with 41mm clear aperture
• Threads into rear cell and works with any brand and size of Schmidt-Cassegrain telescope with a standard 2" SCT thread

Meade and Celestron both produce exactly the same reducer. Probably in the same factory, the only difference is the branding.

NOTE: Will NOT work with Celestron EdgeHD or Meade ACF telescopes
