Used ZWO 5-Position EFW (5x1.25") w/ZWO LRGB filters installedThis is a ZWO 5 position filter wheel that has unmounted 31mm ZWO LRGB filters already installed, leaving one more slot open for the filter of your choice. The filter wheel and filters are in excellent shape, with clean ZWO LRGB filters, and only some minor marks on the filter wheel housing that won't affect its function or use. Comes as you see it in the photos; no cord, no box (except for a box for the already installed filters). The Next Generation
