The ZWO Electronic Filter Wheel Mini (EFW Mini)
The smallest and most lightweight 1.25″ Electronic Filter Wheel in the world, only 300 grams.
The body is CNC machined from a full block of aircraft grade aluminium and is a very thin 20mm thick.
The step motor is the heart of the EFWmini, which is made by NPM from Japan. You can trust its quality and relability.
Supports both 5*1.25″ filters or 5*31mm filters and 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.
So 1.25″ filters won’t have vignetting up to F5 focal ratio scope and 31mm filter won’t have vigentting up to F2 lens
Our new RGBL filters are recommended to work with ASI1600, it will offer nearly 1:1:1 RGB color balance.
