Mounting of the autofocuser is different on each telescope or better said each focuser. Our 3D printed adapters work best with belt driven autofocusers - the flexibility of printed adapter works as belt tensioner, providing good traction on the focuser knob. It is compatible with the Nema 14 L bracket, which is shipped with the autofocuser. We will develop adapters for aditional focusers in the future. If you wish to order only the adapter and L bracket without the autofocuser unit (in case you happen to have your own solution with Nema 14 stepper motor), contact me.
