TS-Optics 3" Rack and Pinion Focuser - holds accessory to 6 kg - 110 mm travel

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 focuser end we choosed to use todays standard threads of available accessories like field flatteneres and reducers/flatteners to save you money purchasing expensive adapters. Together with experienced amateur astronomers we designed a new rock solid focuser operating ultrasmooth.

Our focusers does not use ball-bearing supports which tend to tilt, our focusers using teflon support which guarantee a complete lack of play due heavy loading.


Connection to the telescope

The focuser has on the telescope side an adapter with M117x1 female thread. With special adapters, you also can connect the focuser to other telescopes, like apo refractors.




More stability and precision - Rack and Pinion System:

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

Question:
Is it possible to switch the dual-speed gear knob to the other side of the focuser?

Answer from Teleskop-Service:
Changing the dual-speed gear knob to the other side, for example for left-handed users, is possible. However, we recommend having this conversion carried out by Teleskop-Service, as the play between the focusing shaft and the rack must also be adjusted.
