Connect your SBIG filter wheel or off-axis guider to your telescope focuser’s draw tube or focal reducer/field flattener with this M48x0.75 adapter plate. This adapter plate has an inside thread that is compatible with many telescopes with a metric 48mm outside thread.
It is designed for the FW8S-Aluma, FW8S-STT filter wheels, the StarChaser SC-2, and the OAG-8300 off-axis guider.
The Adapter plate provides a M48x0.75 thread, the same as found on many DSLR and Mirrorless digital camera adapter rings. (Sometimes erroneously called a “Wide-T” ring).
When you are ready to step up from a consumer digital camera, this adapter plate makes it easy to attach your new SBIG equipment.
This plate may possibly vignette when off-axis guiding. It is preferable to the T-thread plate for this purpose.
