Quick answer

Install the DirectSync ES30 motor on your Explore Scientific 3" HEX focuser for both manual and motorized focusing. The built-in clutch lets you switch modes without tools.

Why choose the DirectSync ES30 motor

The DirectSync ES30 motor is designed specifically for the Explore Scientific 3-inch Hex Focuser. It features a built-in clutch mechanism and temperature sensor, allowing you to focus manually or automatically with a simple twist of the motor housing. This upgrade eliminates the need to choose between manual and motorized control.

Installation is straightforward, and the motor works seamlessly with the FocusLynx Control Hub for remote or automated focusing. The temperature sensor helps compensate for focus shift during observing or imaging sessions.

Installation and setup steps

  1. Prepare the focuser: Remove the existing manual knob or cover from the Explore Scientific 3-inch HEX focuser. Ensure the focuser drawtube is clean and moves freely. Common mistake: Forgetting to clean the focuser threads can cause binding.
  2. Attach the motor: Align the DirectSync ES30 motor with the focuser's mounting flange. Tighten the retaining screws evenly to avoid misalignment. Common mistake: Overtightening can warp the motor housing or strip threads. Use a torque-limiting screwdriver if available.
  3. Connect the cable: Plug the motor cable into the FocusLynx Control Hub or compatible controller. Route the cable away from moving parts. Common mistake: Pinching the cable in the focuser or mount can cause intermittent connection. Secure the cable with zip ties to prevent snagging.
  4. Test manual and motorized modes: Twist the motor housing to engage or disengage the clutch. In manual mode, focus by turning the housing. In motorized mode, use the controller to autofocus. Common mistake: Not testing both modes before a session can leave you stuck in the wrong mode. Practice switching modes in daylight.
  5. Calibrate the temperature sensor: Use the FocusLynx software to set the temperature compensation parameters. Let the focuser acclimate for 10 minutes before imaging. Common mistake: Skipping calibration can cause focus drift during a long session. Re-calibrate if the ambient temperature changes by more than 10°F.
