ZWO Filterrad EFW 7x 2" (88229)

ZWO Filter Wheel EFW 7x 2" (88229)

The motorized filter wheel enables convenient filter changes directly through the camera control system. This allows for contact-free operation while maintaining precise focus. Filter changes can also be automated, ensuring smooth and efficient imaging workflows.

Control and power are supplied easily via the camera’s USB 2.0 hub, reducing cable clutter and simplifying installation.

Because the filters are positioned only 10 millimeters from the sensor, edge shading is effectively prevented—even when using fast, high-performance telescopes.

Software Compatibility and Design

• Fully compatible with ASIAIR, ASIStudio, ASCOM, and the ZWO SDK, providing flexible control across different platforms.

• True plug-and-play functionality with a driver-free design, meaning no additional driver installation is required.
