This product has been discontinued and is no longer available from the manufacturer. The CFW5C filter wheel is designed for the ST-5C and ST-237/A cameras. It operates the same as the larger CFW8A except that it fits inside the camera head. The filters used in the CFW5C are exceptionally high quality RGB filters designed for parfocal operation at the fast focal ratio of Celestron's Faster optical systems. The band passes are also slightly different from the larger filters to better match the spectral response of the TI CCDs used in these cameras.
