TS-Optics 2.5" Rack and Pinion Focuser - supports up to 6 kg - travel 95 mm

Since years, Teleskop-Service has looked for an alternative to high-end focusers for an affordable price. Now we can offer a very good high end focuser for an incredible price.

At the camera side we choosed to use today´s standard threads of available accessories like field flatteneres and reducer/flatteners, to save you money purchasing expensive adapters. Together with Images we designed a new rock solid focuser operating ultra-smooth.

Telescope side connection - M90x1 female thread:

The TS 2.5" rack and pinion focuser is attached to the telescope via an M90x1 female thread adapter. A 360° rotation is also included - guaranteed without tilting. The connection fits directly to the RC astrographs of GSO and AstroTec.

For DIY construction, an 81 mm push-in barrel connector is included.

We also offer individual adaptations to your telescope, just ask us.

Camera side / eyepiece side connection:

The TS 2.5" rack and pinion focuser has a M63x1 connection thread on the camera side. This allows direct screwing of corrector systems like the TS 2.5" full-frame flattener for refractors or the Riccardi M63 reducer for refractors and RC telescopes.

In addition, a reduction to 2" receptacle (compression ring with 3 screws) and a reduction from 2" to 1.25" are of course included in the scope of delivery.

More stability and precision - rack and pinion system:

Our focusers does not use ballbearing supports which tend to tilt, our focusers use teflon support which guarantee a complete lack of play due to heavy loading. The transport of the draw tube is completely seperated. This offers best possible stability and smooth movement.
