About this product

The TS 2.5" Rack and Pinion Focuser is a high-quality 2.5" focuser with a max payload capacity of 4kg

Telescope side connection - M117x1 female thread:

The TS 2.5" rack and pinion focuser is attached to the telescope via an M117x1 female thread adapter. 360° rotation is also included -  with no tilting. The connection fits directly to the 10" StellaLyra Ritchey Chretien and Cassegrain telescopes.

Camera side/eyepiece side connection:

The TS 2.5" rack and pinion focuser has an 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 StellaLyra Ritchey Chretien telescopes. 

In addition, a 2" eyepiece adaptor is included (compression ring with three screws), and a 2" to 1.25" adaptor is also included. 

This focuser does not use ballbearing supports, which can tilt. Instead, it uses a  Teflon support, guaranteeing a complete lack of play when used with heavy loading. The draw tube's motion is separated, offering the best possible stability and smooth movement.
