Knobs, Handles & Upgrade Kits

Small parts often make the biggest difference in daily use. A carry handle on the tube rings, a larger azimuth knob that works with gloves on, a Dobsonian brake that stops the tube drifting, or a handle bar that lets you lift a refractor without touching the focuser. This collection gathers those practical upgrades and replacement parts.

You will find Orion Optics UK Dob brakes, radius blocks and CNC mount knobs, Software Bisque Paramount knobs, Baader and William Optics handles, Askar handle bars, PrimaLuceLab PLUS spacers, iOptron and Sky-Watcher brackets, and RB Focus tripod hooks.

Popular Upgrades

  • Carry handles: Make it safer to lift a telescope on and off the mount in the dark, and give a place to mount a finder or guide scope.
  • Larger adjustment knobs: Much easier for polar alignment with winter gloves.
  • Dobsonian brakes: Add adjustable friction so the tube stays put when you change eyepieces.
  • Spacers and radius blocks: Raise rings or accessories to clear focusers and finders, or match curved tube surfaces.
