Astronomy Specialist
The new ZWO Electronic Filter Wheel 7 x 36mm features a larger body and newly-added screw holes to give you a more flexible way of connecting ASI cameras such as the ASI2600MM Pro.
The EFW 7 x 36mm is CNC machined and has an optical thickness of only 20mm. High quality stepper motors from NPM Japan make this a very reliable solution. This model can take 7 x 36mm unmounted filters.
The power absorption of the EFW is only 120mAh @ 5V so any USB cable can power it up.
