Astronomik H-alpha 6nm CCD MaxFR 50mm – High Contrast for Fast Optics imx290 camera the filter performs optimally withAstronomik H alpha 6nm CCD MaxFR 50mm 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 Celestron's RASA and Takahashi's Epsilon Astrographs. Our novel MaxFR emission line filters are suitable for very fast focal ratios. The Astronomik MaxFR series of narrowband emission line filters is perfectly matched to the
