Astronomik SII 12nm CCD MaxFR 31mm Filter for Fast Systems visual observing Blocks wavelengths of mercury andAstronomik SII 12nm CCD MaxFR 31mm MaxFR Astronomik photographic narrowband emissionline filters for fast optical systems. There is an ever growing demand for filters suitable for extremely fast optical systems like Celestrons 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 perfectly matched to the
