Using Astro-Physics, Takahashi, Televue or Borg:
For owners of AP and Takahashi refractors with 2.7" and 4" focusers, there are now available replacement knobs in both 2" and 3" sizes. Finer focuser control is required when viewing the planets and for CCD work. Large Knobs offer that extra control. Finished aluminum knobs are made of 6061-T6 alloy with a fine knurl and polished finished. To install, just remove your old knobs and slip your new knobs onto the focuser shaft and then tighten the brass tipped set screw provided. Large Knobs are supplied in either 2" size for $ 100.00 or 3" size for $ 140.00. Shipping additional.
