Fully Metal 2" 1:10 Dual Speed Focuser for Reflector Telescope w/ 1.25'' Adapter

Description:
This dual-speed focuser is a great to use,focusers eliminate the annoying backlash and image-shift that plagues. You will experience very smooth and precisely controlled focuser motion.
The 2" focuser features a brass compression ring and can accept standard 2" refractor-type diagonals and other accessories. Also included is a 1.25"-2" adapter with brass compression rings and threads to accept standard 2" filters.
This model features a 360-degree rotatable ring that allows you to orient the focuser (and hence your diagonal/eyepiece) to the most comfortable viewing position.
Detachable drive block assembly is reversible for right hand or left hand fine-focus operation and for attaching the Steeldrive motorblock onto Diamond-NT-Steel Tracks for newtonian telescopes.
Shortest possible mechanical design achieves optimum balance between focuser height (backfocus) and rigidity requirements. Zero shift locking knob to precisely stop any movement without affecting optical axis adjustment.
