Product Details

  • The Astronomik 6nm H-alpha filter (a.k.a. Astronomik H-alpha 6nm CCD Clip-Filter EOS APS-C,) is an extremely narrow emission-line filter for CCD photography. The filter lets the H-alpha light of emission nebulae pass and blocks nearly the whole remainder of the spectrum where the CCD is sensitive. The Full Width at Half-Maximum (FWHM) of 6nm is optimized for maximum contrast between the (H-alpha emitting) object and the background. The contrast gain is much higher than with our 12nm emission line filters but you won't see as many stars in the resulting images. The design of the transmission curve makes it possible to use the filters with instruments from 1:3.75 to 1:15.  

    This is an EOS APS-C Clip filter.

    The Astronomik H-alpha-CCD (6nm version)increases the contrast between objects, in this case between the H-alpha emission line and the skyglow background in the same way as the 12nm version. The gain in contrast is much higher due to the smaller FWHM. The 6nm H-alpha filter is the right choice for extremely dim objects, even in the Milky Way, and for observations from heavily light-polluted places. The Astronomik 6nm H-alpha-CCD completely suppresses the emission lines of artificial lighting (mercury (Hg) and sodium (Na)) and skyglow. Transmission losses and chromatic distortions, which arise with other filters, only occur with Astronomik filters when extremely bright aperture ratios come into play.

    Using the Astronomik 6nm H-alpha together with the 12nm H-alpha gives you the ability to have a maximum contrast in the Hii objects and to keep the stars in the final image. The Astronomik 6nm H-alpha filter may NOT be used for solar observation. If you plan to do (false-)color imaging with other emission line filters, you should get the matching filters with 12nm FWHM. Images taken with filters with differing FWHM are very difficult to combine into the final image.

    About the Astronomik Clip-Filter System:
    The patented Astronomik Clip-Filter System is black anodized aluminum and laser-cut on state-of-the-art modern machines. It can be inserted within seconds directly into the EOS camera body. There are no changes necessary and all lens functions (focus, screen, image stabilization) remain functional!

    Almost all Canon system lenses (with the exception of the EF-S series) and all M42 and T2 lens adapters, can be used with the Astronomik Clip-Filter System. The Clip-Filter System also acts as an outstanding dust shield, which prevents the possibility of dust settling on the sensor during long time exposure (The MC-Clear filter does not have a filter effect and only acts as a dust shield.)

    Note 1:For Photographers interested in daylight IR-Photography an "MC-modification" is possible for some cameras. If you are interested in this, please send us a short mail. We will give you more details. The "MC-modification" gives you no advantage for normal astrophotography!

    Note 2: The Astronomik Canon EOS clip is not suitable are cameras offered before 2003 and all varieties of the Canon EOS 1D and Canon EOS 5D or 6D.
