สาย Sky-Watcher slow motion control cable sets สำหรับ EQ3 EQ3-2 mount
Intended primarily for Sky-Watcher EQ3 and EQ3-2 and Celestron equivalents but will fit other similar mounts. Also known as 'Slo-Mo' cables, they assist the manual centring and smooth tracking of targets.
This pair of flexible slow-motions lets you comfortably move the two axes of your mount. It makes tracking an astronomical object in the right ascension axis enormously easier due to the shaft's flexibility and its large control knob.
