Mount drive unit Sky-Watcher Drive in both axes EQ5 SW-4308 (MPN SW-4308)

The Sky-Watcher Drive in both axes EQ5 SW-4308 is a motorized drive unit for equatorial mounts that provides motorized tracking in right ascension and declination. Designed for EQ5-class mounts and compatible setups, this drive unit enables continuous sidereal tracking to follow celestial objects accurately across the sky. It supports visual observation by reducing manual adjustments and also enables long-exposure astrophotography by producing smoother, consistent motion of the mount.

Advantages

This dual-axis drive offers synchronized motion in both right ascension and declination, improving target centering and reducing field rotation during extended exposures. The unit integrates with standard EQ5 mount interfaces to simplify installation and provides reliable motor control that minimizes periodic error when used in typical amateur setups. Its design focuses on steady, low-vibration operation suitable for sensitive observational and imaging tasks.

Suitable for

• Visual observation with equatorial mounts of the EQ5 class
• Long-exposure astrophotography with moderate payloads
• Tracking of planets, stars, star clusters and deep-sky objects
• Amateur astronomers upgrading from manual slow-motion controls

Key specifications

• Motorized tracking in two axes: right ascension and declination
• Compatible with EQ5-class equatorial mounts and similar interfaces
• Enables sidereal tracking suitable for visual use and long exposures
• Low-vibration motor operation designed for stable imaging
• Mount-mounted unit designed for direct integration without major modifications

How to use

Mount the drive unit onto the equatorial mount according to the mount manufacturer’s instructions, ensuring secure mechanical coupling to both right ascension and declination axes. Connect the power and control leads as required by the mount and drive interface. After polar alignment of the mount, engage the drive to start sidereal tracking; use the mount’s hand controller or manual controls to make fine adjustments and centering. For astrophotography, verify tracking performance with short test exposures before proceeding to longer integrations.

Recommendations

For best results, perform accurate polar alignment and balance the payload before use. Check mechanical connections and periodic error characteristics of the mount; combine the drive with autoguiding where higher-precision tracking is required for long focal-length imaging.
