True axis feedback. Power delivered at the saddle.
Servo Direct Drive and high-resolution absolute feedback at the final RA axis provide precise, responsive motion control. Dual USB-C power ports place flexible power delivery close to the camera and accessories, creating a cleaner and more convenient imaging setup.
Servo Direct Drive. True Axis Feedback. Individually Verified.
WD-20EP adds two intelligent USB-C power outputs directly at the saddle, bringing power closer to the telescope, camera and compatible accessories.
This reduces the need to route multiple long power cables around the moving axes, helping create a cleaner installation with fewer loose cables to manage during tracking and slewing.
