TS-Optics 3" Dual Speed Rack and Pinion Focuser - Holds Accessory up to 6kg - 110mm Focus Travel
The TS 3-inch Rack and Pinion Focuser is perfect for astrophotography. Perfect to upgrade or build Refractor telescopes
- The TS 3" R&P Focuser offers much more stability, than typical Crayford focuser. The draw tube travel is 110mm
- Connection on telescope side - M117x1 female thread with 360° rotation
- Connection on camera side - M68x1 female ZEISS Level thread, M78x1 female thread, 2" and 1.25"
- More stability and precision through Rack & Pinion transport of the draw tube
For many years, Teleskop Service have 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 Reducer/Flatteners, to save you money purchasing expensive adapters. Together with experienced amateur astronomers we designed a new rock solid focuser with ultrasmooth operation.
Our focusers do not use ballbearing supports which tend to tilt, instead our focusers using teflon support which guarantee a complete lack of play even under heavy load.
We at 365astronomy also use one of these focusers with our TSAPO130Q refractor telescope. Although the TSAPO130Q comes with a similar focuser, it has got a built-in reducer/flattener and so by using this focuser (TSFOCR30) we can now use it with a non-magnifying flattener at its original focal length, which fits better when imaging smaller deep sky objects.
Connection to the telescope
On the telescope side the focuser has got an adapter with M117x1 female thread. With special adapters, you can also connect the focuser to other telescopes, like APO refractors.
More stability and precision - Rack and Pinion System:
These focusers do not use ballbearing supports which tend to tilt, instead our focusers using teflon support which guarantee a complete lack of play due heavy loading. The transportation of the draw tube is completely seperated. This offers best possible stability and smooth movement.
