ZWO EAF Bracket for Celestron C8 and C9.25 SCT Telescopes

ZWO EAF Bracket for Celestron C8 and C9.25 SCT Telescopes

Key Features & Benefits

• Designed specifically for Celestron 8-inch and 9.25-inch SCT/EdgeHD optical tubes. Compatible with C8, C9.25 and also works with larger models depending on bracket variants.

• CNC-milled from aircraft-grade aluminum for high precision, durability and lightweight installation.

• Provides a direct mount for the ZWO Electronic Automatic Focuser (EAF) onto Celestron SCTs without needing additional adapters like the Feather-Touch focuser.

• Secure mechanical coupling ensures stable and repeatable focusing — essential for astrophotography workflows where fine focus changes matter.

• Optimised design for imaging setups: minimal flex, high positional repeatability, ideal for camera + filter wheel + OAG train on SCTs.

• Easy installation on compatible OTA; supports integration with ZWO’s autofocus system (via ASIAIR, Sesto Senso, software) or manual motorised focuser setups.

Ideal Use Cases

• Amateur and semi-professional astro-imagers using Celestron 8″ or 9.25″ SCT or EdgeHD telescopes who want to motorise or automate focusing with the ZWO EAF system on their optical tube.

• Visual-observers who occasionally switch to imaging and want a robust mounting solution for a focuser motor on their SCT.

• Users upgrading to motorised focus control (for example to use autofocus routines) and needing a quality bracket to integrate ZWO’s EAF onto their C8/C9.25 OTA.
