Motor Focuser fixing points on an Esprit 150?
Does anyone know the correct mounting points for a motor focuser on an Esprit 150? Looking at the bottom of the focuser there are four slotted screwheads that seem to be set in concrete. Are these the best place? Also how do you get the focuser knobs off. The x10 knob comes off easily by undoing a screw, but there are no obvious screws for the large knobs. Again they appear to be set in concrete if you pull them. The focuser is a Pegasus cube on an L bracket.
