Astronomik SII 12nm CCD MaxFR 2'' (M48) Filter for Fast Optical Systems Tripod Mount Clamp and this laser collimator providesAstronomik SII 12nm CCD MaxFR 2'' (M48) MaxFR Astronomik photographic narrowband emissionline filters for fast optical systems. There is an ever growing demand for filters suitable for extremly fast optical systems like Celestron's RASA and the Epsilon Astrographs made by Takahashi. Our novel MaxFR emission line filters are suitable up to very fast focal ratios. The new Astronomik MaxFR series of narrowband emissionline filters is perfect matched to
