About this product
Part Number: ZWO-EFW-5x2
New ZWO 5x 2" electronic filter wheel (EFW).
The filter wheel body is CNC machined from a single block of aircraft grade aluminium for maximum strength and rigidity. It also features a quality Japanese-made stepper motor.
Only 20mm thickness.
Also available in 7x 2" variant.
- Supports 5x 2" mounted or 50.4mm (+/- 0.5mm) unmounted filters.
- Quality Japanese-made stepper motor.
- Rotates in both directions for faster filter selection.
- CNC-machined from a single block of aircraft grade aluminium.
- Powered by USB - max consumption around 120ma@5v.
- ASCOM driver.
There is no need for multiple cables to power this wheel, just one USB cable will suffice. The maximum power requirement is approximately 120mAh @ 5V, so it can be operated from the Cooled camera's USB2.0 port.
When connected to a ZWO ASI6200, the distance from the filter to the sensor is about 18mm
ZWO recommend their 2″ RGBL filters which work well with the ASI6200MM Pro camera and provide nearly 1:1:1 RGB colour balance.
The requirements shown below must be met if using non-ZWO 2” filters.

Setup was nice and simple Had to make a small adjustment to my train to get back to 55mm back focus. Once that was done I ran into a slight issue in use. I calibrated the wheel and it all seemed ok but I got a message saying "It is detected that carousel is slipping or blocked. There is possibility that the space between motor stalk/shaft might be too loose or too tight or the central fixing screw of the carousel is too tight The answer was in the message. undid the cover plate, in the centre of the wheel is a screw covered in black felt. Remove the felt carefully adjust the screw with a flathead screwdriver. For me it was just a little to tight. Once done I calibrated again, problem solved.
My rig required a re-balance as it adds some weight to the rear of the imaging train.
Very nicely engineered bit of kit.
