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.

Suitable for: Newtonian telescopes with 230-250mm tube diameter.
Connections on the camera side: 2" male and M82x1 female thread
Micro reduction: present
Minimum height to M82 thread: 83 mm from base
Minimum height up to the 2" connection: 99 mm from the base
Distance of the holes at the base: 100 mm lengthwise - and 83 mm crosswise to the tube (circumference)
Required screws for adaptation to the tube: M5
