ZWO EAF Electronic Focusers

ZWO EAF electronic focusers are motors that attach to your existing focuser and drive it from an ASIAIR, N.I.N.A. or other ASCOM software for precise, repeatable autofocus. The collection includes the EAFN and the EAF Pro wireless model.

Brackets fit Celestron C8/C9.25 and C11/C14 SCTs and Takahashi focusers, a temperature sensor lets the software refocus as the night cools, and the EAF Hand Controller allows manual adjustment at the telescope.
