Tecnosky Precision 2" S high precision focuser

Tecnosky Precision 2" S high precision focuser. S (short) version with 35 mm focuser drawtube extension.

The Tecnosky Precision 2S is a rack an pinion focuser that deliver high precision positioning. This is the S (short) version with 35 mm focuser drawtube extension.

The focuser is CNC machined and the motion is delivered throuch a rack & pinion system, helped by 8 ball bearings . This allows to minimize any play or flexure, a very important feature for serious astroimaging.

There is also a 1:10 demultiplicated knob for fine focusing.

The focuser accepts 2" barrels and you have 3 knobs that acts on a brass retaining ring. There is also an M63x1 thread for direct coupling, e.g. cameras and so on.

On the telescope side there is a conical attacgment 77.9 mm wide directly compatible with the GSO newtonians. Other flanges for other instruments are optionally available (SCT, RC GSO, Skywatcher refractors, ...).
