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 systems, including the new Meade ACF f/8 systems. This reducer/corrector comes with 3" barrel and adaptors for Nikon and Canon DSLRs. Maximum free optical aperture is measured at 65mm.
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.
Please note: this reducer willl not work with the Explore Scientific f/6 ED80. We recommend the TeleVue TRF2008 for all Explore Scientific 80mm Apos.
