Focal Reducers / Correctors TS Universal 2-Inch Field Flattener for Refractors from f5 to f8 £169.00
The TS Universal 2-Inch Field Flattener for Refractors from f5 to f8 is a flat field imaging corrector for almost ALL refractors with a 2″ focuser, producing pinpoint stars from centre to edge!
The flattener has an optical diameter of 45.5 mm and offers reduced vignetting compared to narrower T2 types. Fitting is M48 at both ends.
For most refractors the optimum back focus distance is around 109mm from the M48 thread to the camera’s sensor.
Experience has shown that the flattener has a large tolerance for deviations from the ideal distance. A 5% deviation does not cause any deterioration of the image quality with an APS-sized sensor.

The SkyWatcher 2″ Field Flattener is a superb quality, non-focal reducing Field Flattener optimised for DSLR imaging on refractor telescopes with focal ratios of between f/5.5 to f6.0.
Will also provide much improved results on refractors with focal lengths narrowly outside this optimised f/range. Integral T-Ring adaptor thread. High quality CNC machined body with gloss black anodised finish.

Revolution Imager 0.5x Reducer, increases field of view and makes low surface brightness and extended objects much easier to find and view.
Works on any C/CS camera with a 1.25″ threaded nosepiece and accepts 1.25″ filters.
Exact reduction ration varies with distance to sensor and can usually be optimised for the camera / scope combination in use – ask if unsure.Sale! -
The Antares f6.3 SCT Reducer Corrector provides a faster f/6.3 system for imaging or visual use when used with an f/10 SCT or other compatible telescopes. This item sold well and feedback suggests this reducer is at least as good as, and probably better than, other leading f/6.3 focal reducers sold on the market for more.

The Antares FR2 0.7X 2 inch Focal Reducer is fully multi-coated and takes advantage of the latest computer aided design techniques to achieve the highest standards of performance to dramatically increase the field of view (FOV) or imaging scale of your telescope / camera. The Antares 2 inch 0.7x focal reducer screws directly to the 2 inch filter threads (M48) found on many eyepieces, camera nose-pieces, extension tubes, star diagonals etc.
