Used QHY EFW2-S 5-Position 36mm Filter Wheel

The small version of the QHY Color Filter Wheel is only 15.5 mm (0.61-inch) thick and weighs just 0.8 ounces. The standard carousel for the QHYCFW2-S has five positions and accepts 36 mm unmounted filters.

The filter wheel body has six M3 screw holes on the telescope side that will accept the QHY OAG (off-axis guider), as well as four 3 mm holes on the camera side which can be used to connect a QHY InterCam Series camera.

    • A specially designed filter disk allows you to use unmounted filters with thicknesses from 0.7 mm to 5 mm.
    • The CFW2 motor resides in one corner of the filter wheel for increased work area.
    • USB port support and powered by USB when connected with computer.
