Sky-Watcher Wave 150i Strain Wave Mount

Built around a Strain Wave harmonic drive system, the Sky-Watcher Wave 150i combines substantial payload capacity, precise tracking and compact dimensions for astrophotography and portable astronomy.

The mount head weighs only 5.8 kg while providing a 15 kg payload capacity without counterweights. Using the optional counterweight kit increases the payload capacity to 25 kg.

The Wave 150i can operate in both equatorial and alt-azimuth modes. Its 0–90° latitude adjustment range provides considerable flexibility for different setups.

The drive system combines stepper motors, belt transmission and harmonic reducers. This architecture provides precise tracking with minimal mechanical backlash while maintaining an excellent payload-to-weight ratio.

Wi-Fi and Bluetooth are built directly into the mount. Control is available through the Sky-Watcher SynScan PRO app for Windows, iOS and Android. An optional SynScan handset can also be used.

Strain Wave Harmonic Drive

The Wave 150i uses harmonic reduction gearing.

This design provides a compact mount capable of carrying a substantial payload relative to its own weight.

The transmission combines:

• Stepper motors
• Belt drive
• Harmonic reducers

Harmonic specifications are:

• R.A. axis : 17-100
• DEC axis : 14-100

The reduction ratio is 300:1 on both axes.

Payload Capacity up to 25 kg

Without a counterweight, payload capacity is 15 kg.

With the optional counterweight kit, capacity increases to 25 kg.

The counterweight kit is available separately.

Only 5.8 kg Mount Weight

The mount head weighs 5.8 kg.

Its payload-to-weight ratio makes it suitable for both permanent and transportable astronomical systems.

Equatorial and Alt-Azimuth Modes

The Wave 150i can operate in:

• Equatorial mode
• Alt-azimuth mode

Both R.A. and DEC axes also feature Home positions and axis limit functions.

0–90° Latitude Range

Latitude adjustment covers the full 0–90° range.

A latitude scale is integrated into the mount.

Red LED Illumination

The latitude scale and bubble level feature red LED illumination.

This makes them easier to read during night-time setup.

Dual-Fit 45 and 75 mm Saddle

The Wave 150i is supplied with a dual-fit saddle compatible with:

• 45 mm dovetail bars
• 75 mm dovetail bars

Maximum Speed of 10° per Second

Maximum slewing speed is:

• 2400x
• 10° per second

This allows rapid movement between different areas of the sky.

R.A. Power-Off Braking

The right ascension axis features a power-off braking function.

R.A. Lock Function

A right ascension lock function simplifies counterweight installation when the optional counterweight kit is used.

Home Positions and Axis Limits

Both R.A. and DEC axes feature Home positions.

Axis limit functions are also provided for both axes.

Cable Management Function

The Wave 150i features integrated cable management to simplify installation of equipment connected to the mount.

Wi-Fi and Bluetooth Control

The Wave 150i can be controlled wirelessly through:

• Wi-Fi
• Bluetooth

It is compatible with the Sky-Watcher SynScan PRO application for:

• Windows
• iOS
• Android

A SynScan handset can also be used but is available separately.

Software Compatibility

The mount is compatible with:

• Stellarium
• SkySafari
• Cartes du Ciel
• ASCOM
• INDI

This enables integration with a range of astronomy and astrophotography control environments.

Integrated Connectivity

The mount provides:

• USB-B port
• Autoguider port
• SynScan handset port
• Power input

Precision CNC-Machined Body

The Wave 150i features a precision CNC-machined body.

Carrying Case Included

A foam-lined carrying case is supplied.

It protects the mount head during storage and transport.

Power Requirements

The Wave 150i requires:

• 12 V DC
• 2 A
