ZWO EFW 8 x 1.25″

 

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


The heart ofEFW 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.

Our new RGBL filters are recommended to work with ASI1600, it will offer nearly 1:1:1 RGB color balance. 

How to install the filter? 

1.25″ filters required to be: threaded  shorter than 3mm in length,  without threads less than 7mm in height 

  1. Take the back cover off
