Wanderer Astro FETA M92

Multi-Functional Three-Point Focuser and Tilt Adjuster

• Three points, one precision tool. The FETA M92 uses a three-point independent adjustment mechanism that handles automatic tilt correction and doubles as a high-precision motorized focuser, so one compact unit covers two jobs in your imaging train.
• Tiny footprint, serious travel. With a body just 20mm thick and only 15mm between the two M92 mounting surfaces, the FETA M92 still delivers 4mm of adjustment travel, 236,467 steps per millimeter, and an effective positioning accuracy of 0.2 microns.
• Built for big imaging trains. Rated for an 8kg payload when the center of gravity sits 100mm from the FETA M92, it is ready for most full-frame and medium-format setups.
• Ready for unattended nights. Compared to the Wanderer ETA M54, the FETA M92 features an absolute mechanical zero position with automatic zero detection, so you can trust it during remote and unattended sessions.
• Light-tight by design. A fully enclosed structure with enhanced light-leak prevention blocks direct light from entering the device, keeping your frames clean.
• Engineered to be light. Every detail was analyzed to cut weight without sacrificing rigidity, and the main body comes in at around 750g.
• Threads your way. Both sides feature M92 female threads by default, and two included adapters convert either side to M92 male, M85 female, or M85 male, so the FETA M92 fits a wide range of optical configurations.
• Stacks with the WandererRotator. Paired with the WandererRotator, the total system thickness is only around 35mm, making it one of the thinnest focuser and rotator combinations on the market.
• Adapters for popular systems. Optional adapters are available for Moravian C3, C4, and C5 systems and Takahashi Epsilon optics, with more mounting solutions in development.
• Software that plays well with yours. The WandererEmpire software offers a clean control and visualization interface, automatic tilt adjustment works through seamless NINA integration, and an ASCOM focuser driver is built in.
