ZWO EFW7 - 7-Position Electronic Filter Wheel
for 36mm Filters

The ZWO EFW7 can hold up to seven (7) 36mm unmounted filters.

The EFW7 body is CNC machined from aircraft-grade aluminum and is black anodized. It is sturdy and reliable, yet weighs just 14 ounces and 20mm thick. Inside, a NPM stepper motor (made in Japan) is used to rotate the carousel either clockwise or counter-clockwise. The EFW7 is powered via USB, and includes a cable that can be plugged into the USB2.0 hub of ZWO cooled cameras.
