    One would have to remove a knob on the focuser which is what other Stepper motors do then attach the unit to be able to then control the Focuser, So in fact the EAF is a Stepper motor in a metal housing as others on the market with the exception it will be controlled with ASIair via Tablet / Smart Phone – Laptop ,which is what makes it unique to us who wait for its release!
