Bresser EXPLORE SCIENTIFIC 3 0.7x Reducer/corrector

The EXPLORE SCIENTIFIC 3" 0.7x Reducer/corrector, reduces a compatible telescope's focal length by a factor of 0.7x (for around f/8) and 0.8x (for around 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 Explore Scientific ED-APOs 102mm and 165mm (please note, this will not work on the Explore Scientific 80mm ED Apo refractors though). With certain telescope focal lengths, a slight restriction of the correction at the edge of the image field can be expected when using full-frame sensors. This unit comes with 3" barrel adaptor for direct focuser thread M54x0.75 (the standard focuser thread of the Explore Scientific Essential series of ED Apos) and T2 camera adaptor. This reducer/corrector features a free aperture of 65mm , so that it can be used even with cameras that have a large sensor - if the telescope allows for this.

Note: As previously mentioned, this Reducer/corrector comes with a screw on ring, which fits the standard focuser thread of the Explore Scientific Essential series of ED Apos. For telescopes which are equipped with the 2.5" HEX Focuser, the optional screw-on adapter part no: 0510366 is needed. Other telescopes, not in the Explore Scientific range, with standard 2" push-fit focusers will need the Explore Scientific 2" Adaptor for 3" Corrector - part no: 0510364 to get this reducer correctly fitted.
