If its the native focusser, it seems to be quite solid (no sag evident?).

Thanks Martin.
It's the standard AP 3.5" focuser the 'scope came with.
It shares the same 10:1 feather-touch worm as AP 4" drawtubes.
I've not noticed any sag, but the focal plane needs to orthogonal within 5 micron...hence the application of a little shim stock.
For convenience, I will be installing the feather-touch electronic focus motor. The standard focuser has been designed to be unbolted completely to make way for third party units if required.
