Read MoreThe Meade 07049 f/6.3 Focal Reducer & Field Flattener is a 4-element multicoated 41mm lens in a metal cell which threads upon the 2.00"-18 rear cell thread of any 8.0-16.0" Meade Schmidt-Cassegrain or Ritchey-Chretien telescope. It also is compatible with Meade's APO refractors and their 7.0" Maksutov-Cassegrains-though not ideal for them, because they don't benefit from the field-flattening influence.
