Okulárový výťah TS Optics 3" rack and pinion focuser for Newtonian telescopes - carries up to 6 kg

Teleskop-Service has been supplying and producing telescopes for amateur astronomers and astrophotographers for years now. Our goal is to equip these telescopes with first-class focusers for a reasonable price.
We are pleased to offer you a very good Newtonian focuser, for a first-class price, which will also fulfill demanding astrophotographic tasks. The focuser is suitable for retrofitting and do-it-yourself Newtonian telescopes when larger correctors are to be used, for example with M68 screw connectors.

The advantage - bearing of the drawtube and adjustment are decoupled:
The drawtube is supported on precise bearings. In contrast to Crayford focusers with ball bearings, the drawtube does not give way even under maximum load. The adjustment of the drawtube is achieved via a helical pinion.
The advantage is, on the one hand, very sensitive adjustment even under maximum load, combined with the best possible frictional connection. Even heavy cameras are held well and the field sharpness is maintained.
