Aurora R. ★★★★★

The M117 to OPTEC-2400 threaded adapter finally let me attach my TCF-S focuser to the AT10RC without any wobble. The threading was precise and snug, exactly what I needed for repeatable focus.

Leo I. ★★★★★

This adapter solved my spacing issue perfectly when I swapped focusers on my 12-inch RC scope. The M117 x 1mm threading matched up precisely, so no wobble or play at all. Feels solid and well-machined.

Hannah ★★★★★

Threaded straight onto my TCF-S focuser without any wobble, and the 1mm pitch matched perfectly. Held collimation through a whole night of imaging the Rosette. Finally got my AT12RC rig dialed in.
