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 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 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 Baader MPCC Mark III now improves image quality in reflectors down to F3.5.
Fits 2″ focusers and has rear 48mm and T threads, covers up to 35mm format.
Available in Photo and Photo / Visual versions.
The 2nd generation NextGen MAXfield NGM 0.33X Telecompressor Lens is perfect for AstroVideo / EEA with camera sensor sizes up to 11mm diagonal. It’s supplied with adaptors to most C / CS mount cameras such as those from Mintron, Watec, SX, Mallincam, AVS, QHY & ZWO
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.
