The Explore Scientific 3in 0.7x Reducer - Corrector reduces the effective focal length of a particular instrument by the factor 0.7x (for f/8) and 0.8x (for f/10) respectively. The reducer/corrector not only reduces the focal length but also operates as a very effective field flattener. Although originally developed for the Explore Scientific ED-APOs 127mm and 152mm, the reducer can be used with many telescopes, including the Meade ACF f/8 systems. Maximum free optical aperture is measured at 65mm.  This reducer/corrector comes with 3" barrel,  2 x adaptor for direct focuser thread (M53x0.75 / M57x0.75) and T2- adaptor. Free aperture 65mm, so that it can be used even with cameras that have a large sensor - if the telescope allows for this.

Note: For telescopes which are equipped with 2.5" HEX Focuser the optional adapter Part.No. 0510366 is needed.


Pictured left are the various configurations in which the Explore Scientific 3in 0.7x Reducer - Corrector can be mounted on standard Explore Scientific Triplet Apos.  Simply unscrew the eyepiece holder on the Explore Scientific Apo from the main focuser tube and the supplied ES Flattener/Reducer adapter ring screws on to the exposed ring.


This Reducer Corrector is ideal for large format cameras and imager sensors.  Vignetting is exceptionally well-controlled, due to its large aperture.


Please note: Explore Scientific refractors fitted with the newer 2.5" Hexfocus/Hexafoc focuser will require the additional Explore Scientific Hexafoc 2.5" Adapter for 3" Corrector to fit to their focusers.
