Connect your SBIG filter wheel or off-axis guider to your telescope focuser’s draw tube or focal reducer/field flattener with this 2.156″ x 24 thread (STL thread) adapter plate. This adapter plate has an inside thread that is compatible with adapters and draw tubes that mate with the common SBIG STL thread size. It is compatible with the 2″ Nosepiece, 2.156 x 24 thread.
It is designed for the FW8S-Aluma, FW8S-STT filter wheels, the StarChaser SC-2, and the OAG-8300 off-axis guider.
This plate is suitable for off-axis guiding with the FW8G-STT or FW8G-Aluma self-guiding filter wheels. This is the largest diameter aperture plate, providing no or very low vignetting of the guide camera.
