ZWO EFW 8-position Filter Wheel for 1.25" and 31 mm Filters

Inside the CNC body of the ZWO EFW 8 position filter wheel you will find that you can install either 8 1.25" mounted filters, or 31mm unmounted filters.  ZWO supplies screws and washer to hold the 31mm unmounted filters in place.

The aircraft grade aluminum body is light, yet strong.  At only 20mm thick it won't eat up much of the image train and at 14 ounces it is quite light.

There is no need for multiple cables to power the EFW, just one USB cable does the trick.The power consumption of this EFW is approximately 120mAh @ 5V, which can be operated from the Cooled CCD’s USB hub.
