- The latest EFW (Electronic Filter Wheel), larger than the previous but still low on weight. Only 400 grams (14 oz)!
- The body is CNC milled from an aircraft graded aluminum block.
- Very thin design, where it measures only 20 mm on the wheel body.
- The heart of our EFW comes from NPM, Japan, whose the manufactor for the stepmotor and the quality is trustful and reliable. Guaranteed long life.
- The Electronic Filter wheel can be rotated in both counter clockwise or clockwise direction for filter selection.
- There are 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’s USB hub.
- The distance between the filter and sensor is around 10mm when you connect it to ASI1600. So 1.25″ filters won’t have vignetting up to F5 focal ratio scope and 31mm filter won’t have vignetting up to F2 lens.
