Reducers/Flatteners
|  | | | | | Celestron f6.3 Focal Reducer£119.00 This combination focal reducer and field corrector converts the optical systems of f10 Schmidt-Cassegrain telescopes to f6.3 for photographic imaging. Offers a wide field of view with any Schmidt-Cassegrain telescope and reduces exposure time by a factor of 3. Fits both Celestron and Meade SCT telescopes. |

HoTech SCA Field Flattener£189.00 The Hotech SCA system ensures this high quality 2-element multicoated optical flattener is positioned precisely on the optical axis for optimum results. Suitable for f5-f8 refractor telescopes. | | | Meade f3.3 Focal Reducer£127.00 This reducer was designed for use with webcams and similar with 1/2" or smaller sensors. It is not suitable for larger sensors like those fitted to most dedicated imaging cameras. Converts the optical systems of f/10 Schmidt-Cassegrain telescopes to f/3.3 for ultrafast CCD imaging. | | | |

Skywatcher Field Flattener£66.00 New! A high-quality, non-focal-reducing Field Flattener optimised for DSLR imaging on refractor telescopes with focal ratios from f/5.5 to f6.0. Will also provide much improved results on refractors with focal lengths narrowly outside this optimised f/range. | | | Skywatcher Focal Reducers£165.00 These new Skywatcher 0.85x focal reducers are optimised for the Skywatcher Evostar ED PRO series of APO refractors. Effectively reduces the telescope’s focal length by a factor of 0.85x and provides much improved field-edge correction. Use in conjunction with a Skywatcher DSLR-M48 Ring Adapter.
Can also be used with the Equinox 100, 120 and Celestron 80 and 100 APO series when used with a suitable FLO Adapter.
| | | William Optics 0.8x Reducer III (2011)£135.00 This NEW 2011 William Optics 0.8x Reducer/Flattener III is essentially an upgrade of their previous model with superior off-axis performance when imaging with larger sensors.
Optimised for refractors with f-ratios around F7-7.5 |
