SFFX-1 Field Flattener with built-in spacers configured for an SVX102T refractor. 

The focuser end of this SFFX-1 has a draw-tube extension with 75mm male threads that will thread directly into a 3 inch Fealther Touch Focuser.  The draw-tube extension can easily be removed to reveal 68mm male threads that will thread directly into a 3 inch StellarVue focuser. 

The camera end of this SFFX-1 flattener is equipped with 48mm male threads that thread directly into a camera/camera adapter with 48mm female threads.  If your camera has a different size female threads, an alternative camera/camera adapter may be available from StellarVue.  StellarVue designed this version of the SFFX-1 field flattener assuming the standard 55mm backfocus intrinsic to the camera.
