Wiliam Optics ZWO EAFN/ Pro Mounting Bracket
The William Optics ZWO EAF Mounting Bracket for EAFN / EAF Pro (2025) provides a compact, precision-engineered solution for adding electronic focusing to compatible William Optics telescopes. Designed for the latest ZWO EAF motors, this CNC-machined aluminum bracket features a smooth belt-drive system that keeps the motor aligned with the optical tube for improved balance and easier storage.
Its built-in clutch mechanism allows quick switching between manual and electronic focusing, making it a versatile upgrade for telescopes equipped with William Optics modular focusers, including WIFD systems.


Wide Compatibility with William Optics Focusers
The William Optics EAF Mounting Bracket is designed for WO telescopes featuring modular focusing mechanisms, with WIFD focusers recommended for the best fit. It supports ZWO EAFN and EAF Pro electronic focusers, providing a convenient solution for automated focusing. Other compatible WO focusers may have slight dimensional differences, requiring additional effort during installation.
Please Note: ZWO EAF electronic focuser and telescope are not included and must be purchased separately.


Built-In Clutch for Easy Manual & Electronic Focusing
The William Optics EAF Mounting Bracket features a built-in clutch mechanism that allows quick switching between manual and motorized focusing without removing the EAF motor. Its smooth, stainless steel oil-sealed design provides precise, reliable adjustments for greater convenience during observing and astrophotography.


Installation Notes for New ZWO EAFN / EAF Pro (2025)
The updated ZWO EAFN and EAF Pro models feature a 4 mm motor shaft, compared to the 5 mm shaft on older EAF models. However, the installation process remains the same.
Some newer EAF units have a flat stainless steel mounting plate that may leave a small gap between the motor and bracket. If any looseness occurs, simply insert the included 0.2 mm aluminum shim between the EAF and mounting bracket for a secure fit.
