There is no need for multiple cables to power this wheel, 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.

 

The distance between the filter and sensor is around 10mm when connected to the ASI1600 camera.
