Optec TCF 2" to SBIG STL Thread Adapter

This Optec OP-17667 2" to STL Thread Adapter is a 2" to 2.156" x 24 threads per inch male thread Adapter.

This product made by Optec, the model OP-17667 2" to STL Thread Adapter is designed to easily adapt the SBIG and QSI cameras and their filter wheels for the TCF-S focuser.

This OP-17667 2" to STL Thread Adapter by Optec is unique because, by holding tight tolerances (± 0.003") Optec has achieved a slip-fit that is second-to-none. When used with the TCF-S focuser, the OP-17667 with its precision machined dovetail cut exactly matches the three thumbscrews on the focuser's drawtube. By tightening the thumbscrews, the dovetail is drawn tighter to the face of the drawtube completely eliminating flexure.
