ZWO EFW Electronic Filter Wheel 7×36

Description

Introducing the new ZWO EFW Electronic Filter Wheel 7×36

The latest EFW (ZWO EFW Elektronic Filter Wheel 7×36) from ZWO, larger than the previous one, but still low in weight and thin. Only 400 grams and 20 mm thick.

The body is CNC machined from an aircraft aluminum block.
ZWO has decided to make it thinner, where it measures just 20mm on the wheel body. Ideal if you have little back focus.

The heart of our EFW comes from NPM, Japan, whose stepper motor manufacturer and quality is reliable. Guaranteed a long life.

We have two variants

• TYPE1: 8 positions/slots, 1.25 inch or 31 mm filters can be used.
• TYPE2: 7 positions/slots, 36mm filters can be used.

The electronic filter wheel can be turned clockwise or counterclockwise for filter selection.

Technical information

Multiple cables are not needed to power this wheel, just one USB cable is enough. The power consumption of this EFW is approximately 120 mAh @ 5 V, which can be controlled from the USB hub of the Cooled CCD. The distance between the filter and the sensor is about 10 mm when you connect it to the ASI1600.
So 1.25″ filters have no vignetting up to F5 focal length and 31mm filters have no vignetting up to F2 lens.
Our new RGBL filters are recommended to work with ASI1600, it provides almost 1:1:1 RGB color balance.
