AiryFD R51 Focuser Drive for WO RedCat51 EAF Basic version

Looking for the high-resolution version? This way: https://airysc.com/short/airyfdr51highreseaf

A focuser drive dedicated for WO RedCat 51. With elegant structure, high resolution, and perfect integration, your RedCat 51 is upgraded to a powerful weapon for automatic astronomy observation.

Outstanding Design

AiryFD R51 is made of robust aluminum alloy and CNC machining. It upgrades your RedCat 51 to a whole new observation level with a continuous variable speed control. Even so, we still keep some of the convenient functions of RedCat 51! Invertible dew shield, Cat saddle bar installation, and maintaining the mechanism height are some examples. A Picatinny Rail is also included to make more possibilities happen!


We reserve the invertible dew shield function to make it easy for carrying (for RedCat51 I only).

The integration between motor and dovetail maintains the original height of the structure.

Picatinny Rail design provides more extension possibilities.

WO Cat Saddle Bar can be used with AiryFD R51 installed.

EAF Control Box

With the ZWO EAF control box, you can directly control it with your ASIAIR to perform automatic and precise focusing.

The resolution of this combination is 10000 steps/rev., convert it into focusing distance is RedCat51: 1094 steps/mm, RedCat51 II: 825 steps/mm, and the total travel is RedCat51: 32812 steps, RedCat51 II: 28750 steps.
