WARPDRIVE WD-20E Mount
Precision, measured at the axis.
The WD-20E is a new member of the WARPDRIVE EC Series, combining our proven belt-free Servo Direct Drive architecture with high-resolution absolute feedback at the final RA output axis.
The servo motor drives the strain-wave reducer directly, while the output encoder measures the movement of the axis that carries the telescope. The result is a complete RA drive built around direct response, true position feedback and consistent performance.
Servo Direct Drive. True Axis Feedback. Individually Verified.
More control, right in your hand.
The new Advanced Hand Controller combines a 2-inch OLED touch display, precise Hall-effect joystick, built-in GPS and wireless connectivity in one compact interface. Essential mount controls are now faster, clearer and always within reach.
