TEC 0.9x Field Corrector-Reducer
Produced in house, the TEC 0.9x Field Corrector-Reducer, 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. It covers full-frame cameras. The FRC is available for all models and fits with the FTF#3545 Starlight Focuser. The FRC can be used for any TEC telescope. However, one FRC is not universal, each one is constructed specifically for the telescope it will be used with.
