Short description:

Description:
The Tecnosky Precision 2" L is a heavy-duty focuser with a long 60 mm travel and low 44 mm profile, designed for deep-sky imaging where rigidity and stability are essential.

Its drawtube is supported by 8 ball bearings moving along a precision-machined rail, offering smooth and stable motion even when fully extended.

A fine bronze rack with transverse teeth drives the movement, powered by two large knobs. A third 1:10 fine focusing knob ensures micrometric adjustment, while a side screw locks the drawtube axis.

Eyepiece side: M63x1 thread with brass compression ring and 3 locking screws.
Telescope side: 77.9 mm machined cone compatible with GSO Newton bases. Optional adapters allow use on RC GSO, Sky-Watcher refractors, SCT tubes and more.
