The TEC FRC is optimised for use with all TEC Refractors using the Starlight FT3545 Focuser. It provides a corrected field of 70mm and has a nominal back focus distance of 115mm from the centre of the last element to the sensor
The corrector is designed to mount directly to the Starlight Instruments 3.5" focuser as fitted as standard to TEC Refractors. The camera side of the FRC uses a clamping system that requires specific adaption. To aid connection to the widest range of devices easily, we offer an M68 conversion adapter. The clamp may be removed and replaced with a screw on adapter. If you prefer this option, please contact us for details.
