CFW3 Large 7 Position Filter Wheel - 2"/50mm

The QHY CFW3 Large 7 Position Filter Wheel is a compact, third-generation electronic filter carousel designed for 2" mounted or 50mm unmounted round filters up to 10mm thick. Featuring an ultra-thin hybrid stepper motor with bi-directional direct-drive operation, it takes the shortest path between filter positions to minimize rotation time, while a friction drive system eliminates backlash for precision positioning. With a slim 21.5mm profile and dual control modes (USB or 4-pin QHY camera connection), this filter wheel integrates seamlessly into imaging trains while maintaining critical back focus, and is ideally suited for use with QHY600M series cameras and similar astronomy systems.
