Focal Reducer Corrector (FRC) 0.9x

Price : $900

Produced in house, the Field Reducer Corrector, flattens the field of telescopic viewing and reduces the focal ratio by .9x: decreasing it from F/7 to F/6.3. It has a back focus extension of 115mm, making it perfect for deep space astro-photography. The FRC is available for all models and fits with the FTF#3545 Starlight Focuser. While it can be used on TEC’s APO200FL F/8 and APO250VT F/8.8, the FRC works best with TEC’s F/7 models.
