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.

Filters for Astro-Video cameras are hard to recommend due to the relatively short exposures involved.
After many tests this gentle filter (1.25″) has shown merit in reducing light pollution and increasing contrast on all objects.
It is effective mainly in areas where the local light pollution is due to Sodium (yellowish) light.
