The ZWO 7 position filter wheel attaches to the ZWO monochrome camera. It is designed for 2″ mounted filters such as the Chroma LRGB and narrowband filters. As pictured it is populated with Chroma luminance, red, green, blue, Hydrogen-Alpha (3nm), Oxygen-III (3nm), and Sulphur-II (3nm). It works with the 4/3 crop sensor monochrome as well as the full-frame monochrome (possible future)
