Astronomik OIII 6nm CCD MaxFR 36mm Filter for Deep-Sky Imaging dielectric diagonal Three power supply methodsAstronomik OIII 6nm CCD MaxFR 36mm 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 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 the
