ZWO 5V EAF motorized focuser with USB connection
This motorized focuser allows precise focusing. Remote control can also be done via smartphone or tablet because the EAF supports ASIAIR and ASCOM. It can also be controlled via a PC or laptop.
This advanced version also has a handy box for on-site control. Important: The plug must be firmly inserted, otherwise there will be no contact!
A temperature sensor can also be found in the advanced version, which can be used in conjunction with appropriate software to compensate for focus drift when temperature changes.
Flexible adapter plate allows motor focus to attach to TS Optics, SharpStar, Astro Tech, Starlight Feather Touch telescopes and many more.
The main change to the 5V EAF is that the 12V 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 power and data transfer. This makes cable management much easier.
ZWO is constantly expanding the list of focusers that are directly compatible with EAF motor focus. Here is the link to the extract list on the ZWO website: List of ZWO EAF Compatible Focusers and Connection Methods
The EAF motor spotlight also fits the following TS-Optics items, possibly with suitably large washers:
TSAPO85, TSAPO96, TSAPO106, TSAPO106FF, TSED152F5, TSAPO204
The manufacturer specifies an operating temperature range of -5 to +50 °C. In winter it makes sense to use heating sleeves. Two suitable models are linked in the accessories section below.
