Description

The Astronomik H-Alpha CCD Filter 6nm enables high contrast imaging of emission nebulae, even with full moonlight or in light polluted areas.

The contrasts between objects that glow in the H-alpha light and the sky background are greatly enhanced.

The 6nm H-alpha filter dramatically increases the contrast between hydrogen fog and the sky background.

Due to the combination of low half-width and high transmission of almost 100% in the H-alpha line, the filter delivers a maximum signal in the desired wavelength, but blocks all other radiation and thus ensures an extremely dark sky background.

The half width of 6nm is optimally tuned to the use of CCD and CMOS sensors with very low dark current.

The 6nm filters are the first choice if you are watching from a location with extreme light pollution or generally whenever weak objects in very star-rich areas of the sky are to be recorded.

Thanks to the new MFRF coating technology, it is possible to use the filter on all devices up to an aperture ratio of f / 4.

The Astronomik H-alpha filters are not suitable for solar observation!
