The TS Universal 2-Inch Field Flattener for Refractors from f4 to f9 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.
The Celestron 0.7x Focal Reducer for 8″ EdgeHD reduces the focal ratio and increases field of view, whilst maintaining the scope’s excellent image quality.
The SkyWatcher 2″ Field Flattener is a superb quality, non reducing Field Flattener optimised for DSLR imaging on refractor telescopes with focal ratios of between f/5.5 to f6.0.
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 ratio varies with distance to sensor and can usually be optimised for the camera / scope combination in use – ask if unsure.
The SkyWatcher f4 Aplanatic Super Coma Corrector is Optimised for f4 imaging Newtonians, delivering stunning wide-field views with pinpoint stars to the edge of the flat field. Magnification remains unaltered. Features a 4 x element design with one element made from FPL51 ED glass.
TSRCFlat2 a 2″ corrector for f/8 RC telescopes – no effect on focal length
Suitable for all GSO RC telescopes from 6″ to 16″ and for all other F8 RC telescopes. Covers sensors up to full frame.
The SkyWatcher 0.77X Reducer/Flattener for Esprit-150ED is perfectly suitable for image formats up to APS-C, but can also be used for full frame format.
