Astronomik H-alpha 12nm CCD MaxFR 31mm – For Fast Optical Systems planetary astronomy camera you have the possibility toAstronomik H alpha 12nm CCD MaxFR 31mm MaxFR Astronomik photographic narrowband emission line 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 for very fast focal ratios. The new Astronomik MaxFR series of narrowband emission line filters is perfectly matched to
