The ZWO 7 x 2" filter wheel is a larger version of the ZWO 5 x 2" wheel that allows for the installation of seven 2" or 50.4 ± 0.5 mm filters.

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

This product is characterized by a short distance of the filter from the camera matrix, which makes it possible to avoid vignetting even when using high-power telescopes.

Before purchasing a filter wheel, check the required back focus of the camera that will work with it. Examples of connecting the filter wheel are available on the manufacturer's website: astronomy-imaging-camera.com/tutorials/best-back-focus-length-solutions-55mm.html
