Optical Tube Assembly Clamp Tightening-Knob wrench

To achieve a firm attachment between tube and mount you should completely eliminate the gap between the tube's dovetail bar and the mount's clamp, this is best accomplished by lifting the tube with one hand and tightening the clamp's knob with the other hand. A good amount of torque is needed to correctly tighten this knob, in fact you may need both hands in order to apply enough torque to this knob!.

This wrench is specially machined to snug fit on the arm's clamp tightening knob and will make it a lot easier to achieve a firm attachment of the tube every time on the first try!
Please specify which NexStar mount you intend to use this wrench on, SE or SLT.

This item is one OTA Clamp Tightening Knob Wrench for Celestron Telescopes with SLT or SE arm mount.
CNC Machined from white Delrin material.
