Our latest EFW (Electronic Filter Wheel), larger than the previous version but still low on weight. Only 400 grams (14 oz)!

The body is CNC milled from an aircraft graded aluminum block.
We decided to make it thinner - it measures only 20 mm on the wheel body.

The heart of our EFW comes from NPM, Japan, who is the manufacturer for the high quality stepper motor. Guaranteed long life.

This filter wheel has 7 positions for 36mm filters

The Electronic Filter wheel can be rotated in both counter clockwise or clockwise direction for filter selection.

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

The distance between the filter and sensor is around 10mm when you connect it to an ASI1600.

1.25″ filters won’t have vignetting up to an F5 focal ratio scope and 31mm filters won’t have vignetting up to F2

Our new RGBL filters are recommended to work with the ASI1600; they will offer nearly 1:1:1 RGB color balance.
