Know before you buy
No, this is strictly the mounting bracket and hardware. You will need to purchase the ZWO EAF electronic focuser unit separately.
This bracket is custom-engineered for the Celestron C8, C9.25, and RASA 8 Schmidt-Cassegrain telescopes. It is not designed to fit other telescope series.
Installation is straightforward and designed to be user-friendly. The package includes all the necessary mounting hardware, and the bracket is built to align precisely with the existing focus assembly on your compatible Celestron telescope.
Aluminum is used to ensure maximum rigidity and stability. A secure, non-flexing connection is essential for automated focusing to maintain accuracy during long-exposure astrophotography.
Once installed, the ZWO EAF replaces the manual focus knob. The electronic focuser provides the necessary torque to move the mirror, so you will rely on the EAF software for all focusing adjustments.
