The Moravian Instruments EFW-2S-7 is a 7 position filter wheel designed to hold conventional 2" threaded or 50mm round unmounted filters. It is intended to be fitted to a Moravian G2 series camera, typically the G2-8300. This camera requires use of a 2" filter minimum when used with an external filter wheel.
The filter wheel is not available as a separate item. it must be ordered with a G2 camera. The filter wheel will then be supplied fitted to the camera by the factory.
A 7 position wheel allows Red, Green, Blue, Ha, OIII, SII and a clear Luminance or CLS filter to be combined at the same time.
