Wanderer Astro Electronic Tilter ETA M54 (85813)

The Wanderer ETA M54 is a finely adjustable electronic tilt device designed for precise camera alignment without any tilt. This ultra-thin tilt and back focus adjuster is only 5 mm thick, offering maximum precision for optical setups. It is especially suitable for demanding astrophotographers who need remote control over tilt and back focus, eliminating the need for complex manual adjustments.

With its unique structure, the ETA M54 takes up just 5 mm of back focus when directly mounted to an off-axis guider (OAG) or camera using screws. The device weighs only 470 g and features a dual-layer nested design that completely prevents light leakage.

Compatibility with 55 mm Back Focus

When installed alongside a compatible OAG or camera, the ETA M54 maintains the standard 55 mm back focus, ensuring it works with most optical systems.

Three-Point Electronic Tilt Adjustment

Equipped with three independent motors and three high-precision encoders, the system offers:

• Adjustment travel: 1.2 mm

• Motor resolution: 0.005 microns per step

• Positioning accuracy: up to 2 microns

This level of precision is ideal for fast focal ratio telescopes and large-format sensors, providing accuracy far beyond that of traditional manual tilt adjusters.
