Wanderer FETA M92 Electronic Focuser and Tilt Adjuster

Wanderer FETA M92 Electronic Focuser and Tilt Adjuster

The Wanderer FETA M92 is an innovative electronic focuser and tilt (or back focus) adjuster that allows users to accurately and automatically adjust the camera´s focus, tilt, and back focus.

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

4 mm of adjustment travel with over 236,467 steps per millimeter and an effective positioning accuracy of 0.2 microns. With a maximum body thickness of just 20 mm and a recessed M92 female thread on both sides, with only 15 mm between the two mounting surfaces, the FETA M92 delivers exceptional performance in an incredibly compact form factor - 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, the FETA M92 features an absolute mechanical zero position with automatic zero detection, making it more reliable for unattended and remote operation. The 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 35 mm, making it one of the thinnest focuser-rotator systems on the market.

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 750 g.

Extensive Adapter Options

Optional adapters are available for Moravian C3, C4 and C5 systems, Takahashi Epsilons, and other optical systems, making it easy to integrate the FETA M92 into an existing setup. More mounting solutions are continuously under development.

Software

The WandererEmpire software provides an excellent control and visualization interface for the Wanderer ETA. Automatic tilt adjustment is no longer just a dream, thanks to seamless integration with NINA. An ASCOM focuser driver is also integrated.

Note: Automatic tilt adjustment is only available in NINA and requires the Hocus Focus plugin, along with the WandererEmpire software to control the FETA M92.

Installation

The FETA M92 supports both threaded and bolted connections on both sides. Both sides feature an M92×1 female thread (maximum thread engagement 7 mm) and twelve M3 threaded holes (maximum screw engagement 5 mm) for mounting custom adapters. The connection interfaces on both sides are identical; however, when used as an electronic tilt adjuster, you must still distinguish between the telescope side and the camera side during installation, as labeled on the FETA M92.

Note: due to the limitations of the optical system itself, the FETA M92 can only correct tilt; it does not guarantee perfect star shapes, as results are also affected by the collimation of the telescope.
