Sky-Watcher SynScan Kit EQ3-2 GoTo System — Dual-axis hand controller for mount control (MPN SW-4250)

The Sky-Watcher SynScan Kit EQ3-2 GoTo System dual-axis hand controller is designed to operate the EQ3-2 equatorial mount, enabling computerized slewing, target selection and basic tracking functions. The compact controller connects to the mount and provides a SynScan interface for selecting celestial objects, executing automatic slews and improving pointing convenience during visual observing and entry-level astrophotography sessions.

Advantages

The hand controller centralizes mount control with a clear menu-driven SynScan interface, reducing the need for manual adjustments and enabling faster target acquisition. Its dual-axis design allows independent control of right ascension and declination axes for precise positioning. The controller supports automated slewing to catalogued objects and incremental guiding adjustments, which helps improve usability for both visual observation and basic imaging workflows.

Suitable for

• Visual astronomy sessions with the EQ3-2 equatorial mount
• Beginner and intermediate astrophotography requiring computerized slewing and basic tracking
• Educational demonstrations and observational outreach using a GoTo-capable mount
• Field use where compact, portable mount control is needed

Key specifications

• Control type: Dual-axis hand controller with SynScan menu interface
• Functions: Computerized slewing, target selection, basic tracking and incremental guiding control
• Compatibility: Designed for use with the EQ3-2 equatorial mount family
• Physical: Compact, hand-held form factor for portable operation
• Connectivity: Wired connection to mount for command and control

How to use

Attach the hand controller to the EQ3-2 mount using the mount’s dedicated controller port and power the mount according to the mount manual. Use the SynScan menu to enter location and time data, then perform an alignment procedure as described by Sky-Watcher to calibrate the mount. After alignment, select targets from the SynScan object catalog or input coordinates manually, then command the mount to slew. Use the directional controls for fine positioning and the tracking functions to follow objects during observation or imaging.

Recommendations

For best pointing and tracking performance, perform a proper polar alignment and complete the mount alignment routine before slewing to targets. Keep controller cables secured to avoid strain on connectors, and consult the EQ3-2 mount documentation for recommended power sources and alignment options to achieve consistent results.
