COMPUTERIZED MOUNT FEATURES
- All-new design. Sturdier and more rigid with quicker dampening time
- Increased load capacity to 55 lbs.
- Improved motors provide more torque, better slewing and tracking under heavy loads
- Heavy Duty belt-drive system minimizes backlash while providing smooth motor operation under heavy loads
- The spring-loaded brass worm wheel and stainless steel worm gear reduce friction and provide optimum gear mesh
- Internal cabling for worry-free remote operation. Power input and accessory ports remain stationary while the mount slews to avoid snags
- Internal hard stops for both axes prevents cable tension and tripod strike
- Internal optical sensors on both axes for simple and safe remote operation
- Home sensors allow the mount to always start in the index position regardless of orientation before a power reset
- Limit sensors automatically shut off slewing or tracking before reaching the hard stop fail safe
- Brand new control software developed in conjunction with PlaneWave Instruments for professional level control operation and imaging
- The software includes multi-point mount modelling for extremely precise pointing accuracy and many more additional features for remote astroimaging
