Explore Scientific 3" 0,7x Reducer/corrector

Explore Scientific 0.7x focal length reducer / image equalizer for ES APO lens telescopes.

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 127mm and 152mm, the reducer can be used with many systems. For example with the ED-APOs 102mm and 165mm. 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 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.
