The ZWO EFW mini filter wheel is the lightest construction of this type available on the market, allowing the installation of five 1.25 "or 31 mm filters.

The filter wheel is controlled by the software compatible with the ASCOM controller. The wheel can be connected with a USB 2.0 cable to the computer, as well as to the USB outputs located in the camera. The casing is finished in black and is made in CNC technology from the highest quality aluminum alloy used in aviation. It contains a filter wheel drive, the heart of which is a stepper motor from the renowned Japanese company NPM.

This product is characterized by a small distance between the filter and the camera matrix, thanks to which it is possible to avoid vignetting even with high-intensity telescopes (in practice, for the ASI 1600 camera, vignetting does not occur at f / 5 for 1.25 "filters and at f / 2 for filters with a diameter of 31 mm).

Before purchasing a filter wheel, check the required back focus of the camera to work with.
