About this product
Part Number: ZWO-EFW-7x36-II
ZWO V2 7x 36mm EFW (Electronic Filter Wheel)
This new larger version of the ZWO 36mm EFW features additional screw holes on the covers, making connecting it to ASI cameras easier.
CNC-machined from aircraft-grade aluminium, this ZWO filter wheel weighs 400g and is only 20mm thick!
It makes automating your setup and switching filters easy.
- Supports 7x 36mm unmounted filters.
- Only 20mm thick.
- Quality NPM Japanese stepper motor.
- Rotates in both directions for faster filter selection
- CNC machined body from a block of aircraft-grade aluminium.
- Powered by USB (max consumption around 120ma@5v).

Compared to the original 36mm EFW, the new EFW is larger. The screw holes on the front and back covers enable direct connection to ASI cameras, positioning the filters closer to the camera sensor. They also enable it to be matched to a ZWO M68 OAG.
All ZWO 36mm filters fit perfectly in the new 36mm EFW. If you use filters from third-party manufacturers, please ensure the filter's thickness is between 1.5mm and 3.0mm (the thickness of the filter frame is 1.8mm).

This EFW just works, which is what you want. NINA and SharpCap recognised it straight away and i've had no problems with it.

Got this for my 183MM and after speaking to Alex at FLO he suggested I went with the 36mm as I said I would like to add the 2600MM later on. A bit more expensive to start with but means I can just use one filter wheel and one set of filters with the 183MM and the larger 2600MM sensor.
