Introducing 5V EAF, the upgraded version of the original ZWO EAF. This electronic focuser enables precise, dynamic focus control for planetary and deep-sky imaging.
Compared to its old version, the main change of 5V EAF is the elimination of the 12V power supply port. Now you can directly connect the EAF to your camera, laptop or ASIAIR PRO via the USB 2.0 port & cable for both data transmission and power supply. This would not only make the cable management much easier, but also effectively reduce the supply pressure.
5 kg Capacity, ASCOM & ASIAIR Supported
The ZWO EAF works with all capture software supported by the ASCOM platform. The focuser also completes the ASIAIR WiFi imaging and control system. Now control your entire imaging runs from a smart phone or tablet, even from indoors.
Beautiful Design and All Metal Construction
The EAF is constructed from an all-metal housing in an attractive red color that matches our cameras. The innovative pattern on the EAF is inspired by the changes of Airy disk during focusing and the focusing curve, which makes it clear at a glance how this focuser works.
Features:
- Highly integrated design
- Support ASCOM platform and various ASCOM-compatible third-party software
- Support INDI
- Support original software such as ASIAIR and ASIStudio
- Support automatic focusing for DSO imaging
- Support hand controller and manual focusing
- Support temperature sensor
- USB HID device and drive-free
- Stable and durable
There are two variants of the 5V EAF:
Standard Version (This item): EAF body, flexible coupling, motor bracket, USB2.0 cable.
Advanced Version (Sold separately): EAF body, flexible coupling, motor bracket, USB2.0 cable, hand controller, temperature sensor.
You could purchase the standard version first, and then buy other accessories to upgrade.
The casing of the hand controller uses environment-friendly ABS material. It has a 3.5mm female socket. You will have a very comfortable grip when you touch its ergonomic design!
The hand controller provides an easy method of focusing the telescope, featuring IN and OUT buttons, a 2-line display, slow and fast speed rate control.
A “must-have” option for EAF users!
