Description
Offering ready access to the filters needed for monochrome astrophotography, the Electronic Filter Wheel from ZWO is lightweight and simple to operate. The aluminum-housed EFW employs a stepper motor from Nippon Pulse Motors of Japan and can be rotated clockwise and counterclockwise. The wheel consists of seven positions for 50mm square unmounted filters and comes with the necessary adapters for mounting to a telescope back or a camera. Power comes from the supplied USB cable plugged into a computer, USB hub, or camera with power outputs. With the ASCOM driver installed, the EFW can be operated through many astrophotography programs.
