Chinese (Synta) 2' focuser, with all the Chinese grease replaced with
silicone and adjusted so it is reasonably smooth with no play or wobble. Comes with a mounting plate to fit inside the tube of a
Celestron/Vixen 4" refractor or Skywatcher 120mm refractor. (Both have tubes that are about 112mm i.d.)
Price: $45 shipped in continental USA. If you need a 1.25" adapter,
add $10. If you would like alumimun focus knobs made by FocusKnobsDotCom pre-installed, add $15 (These are $24.50 shipped new)
Thanks for looking, Bob.
