Astronomik SII 12nm CCD MaxFR Clip-Filter EOS APS-C for Fast OpticsAstronomik SII 12nm CCD MaxFR Clip Filter EOS APS C 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 Celestrons RASA 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

FMC coating improves color saturation of the image

Webcam / Video (Deep Sky): Suitable if observing OIII objects with heavy light pollution

super emission ability

Optically polished substrate ensures no reduction in telescope performance

DDR3 256M Buffer

Sensor & Imaging Performance

and close-up optical work

Not primarily designed for planetary imaging

allowing convenient operation without needing to interact directly with the radio body

no worry about the cross-frequency with other devices
