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.

There is also a hand box for on-site control included in this Advanced Version. Important: The plug must be inserted firmly, otherwise there is no contact.!

Included in this Advanced Version is also a temperature sensor which can be used together with suitable software to compensate the focus drift during temperature changes.

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.

Question:
The focus motor does not work properly with the hand box, what could be the cause??

Answer from Teleskop-Service:
The cause was (almost) always an incorrectly plugged in cable. This cable is a bit tight, so make sure that it is really plugged tightly in all the way.
It doesn´t matter which end is plugged in where (it has a straight and an angled plug).



Question:
How can I remove the coarse wheel of the focuser of my TS102 Imaging Star??

Answer from Teleskop-Service:
The coarse wheels have two setting screws 90° apart. After loosening the first screw, rotate the wheel by 90° in one or the other direction. Then you find the second screw. After loosening it, the focus wheel can be pulled off.

Remember: You need to remove the single wheel, not the coarse adjustment wheel at the side with the fine adjustment wheel.

"I couldn´t test it for a lot of time, but for the short time I had to use it, it works totally fine and the temperature probe delivered with it is accurate. It was very easy to install on my telescope even without a user manual delivered with it. It provides accurate focus and is very easy to use. Literally plug and play material, here. The hand controller is very light and easy to use as well. "

"Perfect EAF from the ZWO eco-system"

Written by Ralf Schäfer

"Das EAF Motorfokussystem von ZWO-Optical funktioniert sehr gut an meinem Refraktor (TS 115/800 F7 Triplet-APO). Mit Leichtigkeit ließen sich die Madenschrauben auf der Unterseite vom Fokuser am Okularauszug sowie das Rändelrad vom Fokuser abschrauben. Danach erfolgt die Anbringung vom EAF. Es gibt mehrere Adapter je nach Dicke der Welle vom Fokuser. Alles passt, der Sitz ist fest und der EAF hat ein hochwertiges Finish. Danach erfolgt die Fokussierung per Handbox und kleiner USB-Stromversorgung via 5V USB-A-Kabel. Oder der EAF wird via USB-Kabel an die ASIAIR-Box angeschlossen. Dann kann man via APP ferngesteuert über sein Smartphone den EAF fokussieren. Autofokus ist dann möglich und funktioniert auch sehr gut. Der EAF ist sehr empfehlenswert. Eine Anleitung wird hier angeboten."

Der ZWO EAF Motorfokus stabil und gut verarbeitet. Die Montage war eine kleine Fummelei.
Bei meinem 2,5" Hexafoc Fokussierer mit längeren Schrauben 4x20 mm passte dann alles super.
Funktionstest super. Nun wird auf eine sternenklare Nacht gewartet.
