This 2.5" focuser offers a real alternative to high end brands like Starlight Instruments. Unlike many low cost focusers this 2.5" Rack and Pinion design offers smooth and tilt free operation with 1:10 fine focus control and focus lock. The focuser easily copes with loads up to 3kg. It will not tilt or extend on its own.
Internally the draw tube has 92mm of travel is baffled to prevent stray light. The visual back has a self centering 2" clamping mechanism.
If the rear clamp is unscrewed, this reveals an M68 thread allowing easy fitting of accessories such as a 2.5" Flattener. We keep many other adapters and parts that fit the M68 standard so other correctors including the APM Reducers are also easily fitted.
For motorised control of the focus we can also offer the Lunatico Seletek Focus kit for 2.5" R&P which is supplied with a specific bracket for this focuser.
The thread size for screwing directly to a refractor tube is M95
