ZWO-EFW-MINI

ZWO filters wheels make it incredibly easy to rotate between different filters through an astrophotography session. You can even program your filter change routing with the ASIAir.
  • The step motor is the heart of the EFWmini, which is made by NPM from Japan. You can trust its quality and reliability.
  • The Electronic Filter wheel can be rotated in both counter clockwise or clockwise direction for filter selection.
  • Only one USB Cable is enough to power up the EFW, the max power consumption is around 120ma@5V, so you can connected it form the USB2.0 hub of our cooled cameras.
  • The distance between the filter and sensor is around 10mm when you connect it to ASI1600.
  • Very thin design, 20mm and only 300g. Smaller than your hand!
  • The body is CNC machined from a full block of aircraft grade aluminium.

Quick little wheel

It does what it says on the tin. I paired it with a set of LRGB filters also from ZWO and the kit is great.

Switching filters goes much faster than I'd expected, so that's a nice perk.

A must for remote operation

I’m surprised at how quiet and precise the ZWO EFW mini is. Easy to set up. It has one job.. to give the the filter you want when you want it - without having to go to the telescope.

I had originally bought the mini manual

I had originally bought the mini manual. After using that for about a year a half, I figured I would upgrade to the automatic version so that I didn't accidently nudge the telescope every time I changed the filter. This did the job without issue.
