Explore Scientific 3" 0.7x Reducer/Corrector for Apos, ACF, ...
Reduces the focal length 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 flattens the field. Although originally developed for the Explore Scientific ED apos 127 mm and 152 mm, the reducer can be used with many systems. For example with the ED apos 102 mm and 165 mm. Here, a slight restriction of the correction at the edge of the image field can be expected when using full-frame sensors. Comes with 3" barrel, adaptor for direct focuser thread M54x0.75 and T2 camera adaptor. Free aperture 65 mm, 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.
