ZWO 5V EAF Motor Focuser with USB Connector

This motorized focusing unit allows precise focusing. Remote control can also be done via smartphone or tablet because the EAF supports ASIAIR and ASCOM. The control can also be carried out via PC or laptop. Alternatively, there is also a hand box for on-site control.

The versatile adapter plate allows the motor focus to be connected to TS-Optics telescopes, SharpStar, Astro Tech, Starlight Feather Touch and many more.

The most important change of the 5V EAF in that the 12 V power supply connector has been removed. Now you can connect the EAF directly to your camera, laptop or ASIAIR PRO via the USB 2.0 port and cable for both data transfer and power. This makes cable management much easier.
 

Compatibility

ZWO is constantly expanding the list of focusers that are directly compatible with the EAF motor focuser. Here is the link to the listing of focusers on ZWO´s site: ZWO EAF Compatible Focuser List & Connecting Methods.

The EAF motor focus will also fit, possibly with suitably sized washers, on the following apos from TS-Optics:
TSAPO85, TSAPO96, TSAPO106, TSAPO106FF, TSED152F5, TSAPO204
 

Important note

The manufacturer specifies an operating temperature range of -5 to +50 °C. It therefore makes sense to use heaters in winter. Two suitable models are linked in the accessories section below.
