The iOptron Electronic Automatic Focuser (iEAF) is designed to work with Crayford and Rack-and-Pinion focusers and is powered by a 5V USB port.
The focuser allows for precise focus control for deep-sky and planetary imaging. And while the iEAF simplifies focuser control, the convenience of automatic focusing is probably more appreciated during freezing winter nights or hot summer nights when you might otherwise be fighting mosquitos while focusing the telescope.
The iOptron Electronic Automatic Focuser is ASCOM compatible and will work with most planetarium and imaging software. It offers a very quiet operation, has zero backlash and position memorizing during power off. It is lightweight at only half a pound and has a payload capacity of 11 pounds. The focuser can be controlled manually and includes a built-in temperature sensor.
Included in the package is the electronic automatic focuser body, a mounting plate, four adapters for 5 mm, 6 mm, 7 mm, or 8 mm focuser shafts, three Allen wrenches/hex keys (2 mm, 3 mm, 4 mm), a USB2.0 cable for power and focuser control, two M5x10mm socket head screws and washers and two M4x8mm socket head screws and washers.
