TS Optics Focuser 2.5" M117 (71596)

The TS Optics 2.5" M117 focuser is designed for refractor telescopes and features a robust rack and pinion drive system. Unlike traditional Crayford focusers that rely on contact pressure and may slip under heavy loads, this model uses ball bearings to secure the draw tube, ensuring maximum stability and smooth, jerk-free adjustment through a helical toothed rack. The clamping mechanism is optimized to hold the focus position securely without pressing directly on the draw tube, providing reliable and precise focusing even with heavier accessories.
