Sky-Watcher SynGuider Autoguider Camera

Sky-Watcher SynGuider Autoguider Camera


Autoguiding - the easy way. The Sky-Watcher Synguider Autoguider is a revolutionary low-cost fully integrated guiding solution which actively helps you achieve pin-point star images while taking long-exposure photos.

Dispense with clumsy laptops, imaging cables, and setup time - simply plug the Synguider into the guide scope, 12v DC, and attach the ST-4 compatible control cable, and you're ready to go.

The built-in LCD screen gives you real-time information on the guide star as the Synguider keeps your stars on-target. The wired hand control allows configuration of the autoguider settings.

You can easily calculate the angular resolution in arc-seconds using the following formula:

  • Resolution(X) = 2261/FL
  • Resolution(Y) = 1962/FL

Where FL is the focal length of the guide scope in millimeters
