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.
How to install the filters?
To install 36mm filters:
- Take the back cover off
- Lay the wheel down flat
- Hold the filters by the very edges and lay them on the filter wheel slots
- Lock each filter with a "mask" and a set of M2 screws
- Put the cover back on
To use the filter wheel:
- Install the ASCOM driver on your computer
- Plug in the USB2.0 cable
- On the Ascom options, select ZWO filter wheel (1) or ZWO Filter Wheel (2). There are two options to allow 2 filter wheels at the same time.
