Smart, precise and easy to use
The built-in iPolar electronic polar finder makes alignment easy - even when the North Star is not visible. Just plug in your laptop or PC, and the software does the rest. The internal cable system keeps everything neat and prevents cable breakage. The large clamps, even with gloves on, allow you to easily unlock the axles.
The Universal Self-Centering Saddle Works with both Losmandy and Vixen swallowtails, so you can switch between telescopes without any problems.
Quiet power and high precision
The quiet stepper motors track smoothly and accurately without disturbing noise - perfect for balcony observations.
The high-resolution encoders on both axes provide tracking accuracy of less than 0.25 arc second. Thus, in astrophotography you no longer need to use guiding - the mount corrects itself in real time.
