max up to 300M in the open area
improved contrast
Brightness can be adjusted to match observing conditions
looking at the photons of other wavelengths that we do NOT want to record makes the effect of the filter clear: The combination of very good blocking of all unwanted light from UV up to the IR and the narrow bandwidth of the filters reduces all unwanted signals on the sensor

Astronomik SII 12nm CCD MaxFR 2'' (M48) Filter for Fast Optical Systems refractor telescope diagonal max up to 300M inAstronomik 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
