TS 3" Newtonian Crayford Focuser - LINEAR POWER - low profile

... a stable focuser for Newtonian telescopes with base with better illumination

 TS-Optics 3" Newtonian Crayford Focuser - LINEAR POWER - low profile [EN]

 

The 3" LINEAR POWER Focuser is ist optimal for big, fast Newtonian telescopes, where a 2" focuser already would cause vignetting. Through the short construction, a relatively moderate focus position over tube can be achieved. Of course, the focuser has different connecting threads for attaching correctors.

The 3" LINEAR POWER is an improvement of the Crayford principle.

The load does not rest on four - often underdesigned - ball bearings, but on a massively supported and laterally guided stainless steel track at the base. That prevents tilting of the focuser even at high loads. Countering is done via a big thumb screw which presses the inner tube exactly centered on the track. Thus, the load is distributes evenly on the track.

Under loads over 3kg, clamping is achieved with three screws, a central knurled screw and two additional screws. With this clamping, we could not notice any misalignment anymore even under 5kg.

1:10 micro reduction for more accurate focusing ... Of course, the 3" Linear Power also features the reduction.
