TS-Optics 3" rack-and-pinion eyepiece focuser for Newtonian telescopes
The focuser is intended for self-building or improving existing Newtonian telescopes. Astrophotography is the main focus of this focuser. Large correctors can be screwed on directly via the M82x1 auxiliary thread.

Besides the 360° rotation, a special feature is the built-in tilting. This allows a precise tilting of the focuser in order to perfectly adapt the image field to the camera sensor. Especially large sensors with high resolution can thus deliver their full performance.
