Sky-Watcher Wave 100i Strain Wave Mount

Built around a Strain Wave harmonic drive system, the Sky-Watcher Wave 100i combines substantial payload capacity, precise tracking and compact dimensions for portable astronomy and astrophotography.

Weighing only 4.3 kg, the mount head provides a 10 kg payload capacity without counterweights. Using the optional counterweight kit increases the payload capacity to 15 kg.

The Wave 100i can operate in both equatorial and alt-azimuth modes. Its 0–90° latitude adjustment range provides considerable flexibility when setting up the mount.

The drive system combines belt-driven stepper motors with harmonic reducers. This architecture provides an excellent payload-to-weight ratio while minimising mechanical backlash for applications requiring precise tracking.

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, while an optional SynScan handset can also be used.

Strain Wave Drive

The Wave 100i uses a harmonic reduction drive architecture.

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 15 kg

Without a counterweight, payload capacity is 10 kg.

With the optional counterweight kit, capacity increases to 15 kg.

The counterweight kit is available separately.

Only 4.3 kg Mount Weight

The mount head weighs 4.3 kg.

Its payload-to-weight ratio makes it particularly suitable for portable and transportable astronomy systems.

Equatorial and Alt-Azimuth Modes

The Wave 100i can operate in:

• Equatorial mode
• Alt-azimuth mode

It also features R.A. and DEC 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.

Two 45 and 75 mm Saddles

The Wave 100i is supplied with a dual-fit saddle compatible with:

• 45 mm dovetail bars
• 75 mm dovetail bars

A second 45/75 mm dual-fit saddle is also supplied.

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.

This helps maintain control of the R.A. axis if electrical power is removed.

R.A. Lock Function

A right ascension lock function is provided to simplify 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.

Wi-Fi and Bluetooth Control

The Wave 100i 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.

Astronomy Software Compatibility

The mount is also compatible with:

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

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

Integrated Connectivity

The mount provides:

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

Precision CNC-Machined Body

The Wave 100i features a precision CNC-machined body.

This construction contributes to its compact mechanical design.

Carrying Case Included

The mount is supplied with a foam-lined carrying case.

This protects the mount head during storage and transport.

Power Requirements

The Wave 100i requires:

• 12 V DC
• 2 A
