Sky-Watcher SynLink Universal Astroimaging Controller

6 USB Ports and 4 Power Outputs: A Unified Hub for Your Rig

The SynLink is engineered to eliminate cable clutter by providing all necessary connections in one compact box. It features four high-speed USB 3.0 ports for modern imaging cameras, two USB 2.0 ports for guide cameras and accessories, and a versatile USB-C input. Four 2.1mm DC outputs can supply 5 amps each (up to a 10 amp maximum draw) to your gear, while two independently controlled RCA ports manage your dew heaters, preventing frost from forming on your optics during long, cold nights.

The SynLink App: RK3566 CPU Control for Alignment and Autofocus

At the core of the system is the RK3566 processor and the free SynLink app, which runs on Android, iOS, Windows, and macOS devices. The app provides a full suite of tools for modern astrophotography, including guided polar alignment that uses plate solving for precise correction. It also manages multi-star guiding, plate-solved GoTo slewing, and automated autofocus routines, replacing multiple pieces of software with a single, unified interface.

64GB of Onboard Storage for Unattended Imaging Sequences

With 64GB of internal eMMC storage, you can run entire imaging sessions without relying on an external drive or laptop. The SynLink's sequencer allows for fully automated, unattended imaging nights. An "Easy" mode gets you started quickly, while a "Pro" mode unlocks advanced scripting for dithering, autofocus triggers, automated meridian flips, and cloud recovery protocols. When the sequence is complete, you can program the SynLink to park your mount and shut down all connected equipment safely.

1 Serial Port for Sky-Watcher and USB for All

While designed by Sky-Watcher, the SynLink is a universal controller. It supports cameras, focusers, filter wheels, and mounts from many major astronomy brands, automatically recognizing most devices upon connection. For supported Sky-Watcher mounts, a dedicated serial port and included cable provide a direct, reliable connection. For all other gear, the standard USB ports ensure broad compatibility, allowing you to integrate the equipment you already own into the SynLink ecosystem.

SynLink Controller vs. ZWO ASIAIR Plus

The SynLink enters a field dominated by the ZWO ASIAIR Plus, offering a compelling alternative with key hardware advantages. While the ASIAIR is deeply integrated into the ZWO ecosystem, the SynLink provides more flexible connectivity for multi-brand setups.

• ZWO ASIAIR Plus Advantage: The ASIAIR offers seamless, plug-and-play operation with ZWO's full line of cameras and accessories, a mature software platform, and a large user community.
• SynLink Controller Advantage: The SynLink features four USB 3.0 ports compared to the ASIAIR's zero, providing faster data transfer for high-resolution cameras. It also includes 64GB of internal storage as standard and is built from the ground up to support main imaging cameras, focusers, and other devices from a wide variety of manufacturers, not just one.
