TS 2.5" Rack and Pinion Focuser for Telescope Self-Construction and Telescope Upgrade

This focuser is superior to conventional Crayford focusers because bearings and adjustment are decoupled from each other. This allows a sensitive adjustment with a good bearing arrangement, even with maximum load.

Rack And Pinion Adjustment:

A conventional Crayford focuser works with contact pressure. The weaker the pressure, the smoother the focuser, whereby there is always the risk of slipping, because adjustment and bearing are combined. This focuser is quite different:
The draw tube is solidly supported by slide bearings. The bearing arrangement is optimized to achieve maximum rigidity. The adjustment of the draw tube is achieved via a helical toothed rack. The advantage is an absolutely smooth adjustment.
The clamping of the focuser position is also optimized. No clamping screw simply presses on the drawtube, but the position of the adjustment is fixed. The focus position is thus maintained at 100%.

Easy adaptation to your telescope via the M90x1 connection thread:

The focuser has an M90x1 female thread as connection on the telescope side. In addition, you can rotate the complete focuser by 360 to always have a comfortable focusing position. We are also happy to manufacture individual transition adapters for your telescope. Please note, however, that the clear aperture on the focuser of your telescope must be at least 74 mm. This is the diameter of the draw tube with the rack.
