ZWO Filter Wheel EFW 5x 2" (88228)

The motorized filter wheel allows filters to be changed directly through the camera control system. This provides convenient, contact-free operation while maintaining precise focus. Filter changes can also be performed automatically, making imaging sessions smoother and more efficient.

Power supply and control are handled easily through the camera’s USB 2.0 hub, minimizing cable clutter and simplifying setup.

The filters are positioned just 10 millimeters from the camera sensor, which prevents edge shading even when used with fast, high-performance telescopes.
