EFW-7X2

The ZWO EFW-7x2 filter wheel offers precise electronic control of filter positioning during astronomical imaging. It accepts up to seven 2" threaded filters or 50.4mm unmounted filters with a cell height not exceeding 7mm, and is made of black-anodized aircraft-grade aluminum with a thickness of only 20mm, powered by a Japanese-made stepper motor. The bi-directional electronic filter wheel is powered and controlled through the USB port on your camera or directly via a USB cable connected to your computer, requiring no extra power supplies. Ideal for deep-sky imaging, this filter wheel allows seamless integration of a wide range of astrophotography filters, enabling complex filter sequences and rapid adjustments during imaging sessions.
