Astronomik MaxFR-Filters

Astronomik Narrowband-Emissionline filters optimized for fast optical systems!

The MaxFR coating ensures that the Astronomik Narrowband-Emissionline filters can be used with extremely fast optical systems such as the Celestron RASA and the Takahashi Epsilon Astrographs. Unlike other manufacturers' filters, which often require special “High-Speed” versions, Astronomik’s MaxFR filters maintain their transmission characteristics even with normal optical systems.

Filters with MaxFR coating can be used without restriction on the following instruments:

12nm filters with MaxFR coating: Instruments with aperture ratios from f/1.7 to f/6 and approximately 15% reduced transmission at f/1.4
6nm filters with MaxFR coating: Instruments with aperture ratios from f/2.2 to f/6 and approximately 10% reduced transmission at f/2
4nm filters with MaxFR coating are currently in development.
Filters for even faster optics are available on request.

Furthermore, the Astronomik MaxFR coating offers extremely high contrast, minimized stray light, no halos and needle-sharp stars as well as the best possible blocking across the entire spectral range from UV to IR.
