#17667 - 2-inch to 2.156"x24tpi male thread Adapter.
The 2-inch to STL thread adapter was developed to easily adapt the SBIG and QSI cameras and filters wheels for the TCF-S focuser.
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 #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.
