Wanderer FETA M92

Wanderer FETA M92 Motorized Focuser and Tilt Corrector

Designed to combine two essential functions of high-precision astrophotography within a single mechanical system, the Wanderer FETA M92 provides both motorized tilt correction and automated focusing.

Its three-point independent adjustment mechanism allows each axis to move separately for tilt correction. When all three mechanisms operate synchronously, the same system functions as a high-precision motorized focuser.

This architecture makes it possible to manage both sensor orthogonality and focusing from a single device while keeping the imaging train mechanically compact.

Multi-functional

Thanks to its three-point independent adjustment system, automatic tilt correction can be performed without direct mechanical intervention.

When operated synchronously, all three mechanisms move together to provide motorized focusing.

This dual-purpose design adds considerable flexibility when building an imaging train and reduces the need for multiple separate mechanical components.

New Patent

With 4 mm of adjustment travel, more than 23,000 steps per millimeter and an effective positioning capability of 0.2 micron, extremely fine mechanical movement is available for both focusing and tilt correction.

Despite these capabilities, maximum body thickness is limited to only 20 mm.

Recessed M92 female threads are incorporated on both sides, reducing the distance between the two mounting surfaces to only 15 mm.

This combination of precision and compactness reflects WandererAstro's focus on minimizing optical-train length.

High Payload

With a specified payload capacity of 8 kg, calculated with the center of gravity positioned 100 mm from the FETA M92, the system can support most full-frame and medium-format imaging trains.

This capacity makes it suitable for configurations using substantial imaging cameras and accessories.

More Reliable

Compared with the Wanderer ETA M54, an absolute mechanical zero position is incorporated into the FETA M92.

Automatic zero detection allows the system to recover a defined mechanical reference, making it particularly useful for unattended, automated and remote installations.

Additional attention has also been given to preventing light leaks.

A fully enclosed structure prevents direct light from entering through the mechanism and reaching the optical train.

M92 and M85 Interface

Both sides of the FETA M92 feature M92 female threads as standard.

Two standard adapters are included, allowing either side to be converted into different interfaces:

• M85 male
• M85 female
• M92 male

This modular approach provides flexibility when integrating the system into different optical configurations.

WandererRotator Stackable

When combined with the WandererRotator, total system thickness remains only around 35 mm.

This makes it possible to combine rotation, motorized focusing and tilt correction within an exceptionally compact mechanical assembly.

All other equipment shown in the manufacturer's illustrations is for demonstration purposes only and is not included with the Wanderer FETA.

Professional Design

Every mechanical detail has been engineered to reduce weight while maintaining the structural rigidity required for a precision imaging train.

With the main body weighing only around 750 g, the FETA M92 limits the additional load placed behind the telescope while retaining a structure designed for substantial payloads.

Extensive Adapter Options

Optional adapters allow the FETA M92 to be integrated with several existing imaging systems.

Available solutions include:

• Moravian C3
• Moravian C4
• Moravian C5
• Takahashi Epsilon

Additional mounting solutions are continuously under development by WandererAstro.

Software

Designed for the control and visualization of WandererAstro equipment, WandererEmpire provides a dedicated software interface for system operation.

Thanks to seamless integration with N.I.N.A., automatic tilt adjustment can become part of an automated astrophotography workflow.

An ASCOM focuser driver is also integrated, allowing the motorized focusing function to operate with compatible software.

Multi-functional

The three-point independent adjustment mechanism enables both automatic tilt adjustment and synchronized operation as a high-precision motorized focuser, offering greater versatility for a wider range of applications.

New Patent

4mm of adjustment travel with over 23,000 steps per millimeter and an effective positioning ability of 0.2 microns. With a maximum body thickness of just 20mm and a recessed M92 female thread on both sides, with only 15mm between the two mounting surfaces, FETA M92 delivers exceptional performance in an incredibly compact form factor. This is a true showcase of WandererAstro’s uncompromising industrial design.

High Payload

With a payload capacity of 8 kg, calculated with the center of gravity located 100 mm from the FETA M92, it is capable of supporting most full-frame and medium-format imaging trains.

More Reliable

Compared to the Wanderer ETA M54, FETA M92 features an absolute mechanical zero position with automatic zero detection, making it more reliable for unattended and remote operation.

FETA M92 also features an enhanced light-leak prevention design with a fully enclosed structure, blocking any direct light from entering the device. 

M92 and M85 Interface

Both sides feature M92 female threads by default. Two standard adapters are included, allowing either side of the FETA to be converted into an M85 male thread, M85 female thread, or M92 male thread interface, providing flexibility for different optical configurations.

WandererRotator Stackable

Even when stacked with the WandererRotator, the total system thickness is only around 35mm, making it one of the thinnest focuser rotator systems on the market.

**All the other equipment shown are for demonstration purposes only and are not included with the Wanderer FETA.

Professional Design

Every detail of the Wanderer FETA has been carefully engineered and analyzed to maximize weight reduction without compromising structural rigidity. The main body weighs only around 750g.
