Astronomik H-Alpha 12 nm CCD XT Clip Filter EOS M XL - Extra Thin


For deep sky astrophotography with full-frame Canon EOS M camera models under light-polluted skies, this Astronomik H-alpha 12 nm XT Clip-Filter EOS M XL (8h11j0) is an excellent choice! With a 12 nm FWHM and extra thin 0.3 mm carrier substrate, this powerful clip-filter gives you the freedom to use fast optics down to f/3. Crafted to Astronomik's exacting standards, this filter is scratch-resistant, unaffected by high humidity, and does not break down over time.

Please note: this filter must NEVER be used for solar observing or imaging! Doing so will cause permanent damage to your eyes.

Astronomik H-alpha 12nm XT Clip-Filter At a Glance

  • Guaranteed transmission of more than 90% at the H-alpha line (656nm)
  • Mounted on a carrier substrate that measures only 0.3 mm in thickness
  • Enables desired H-Alpha emissions to pass while obstructing nearly the entire rest of the visual spectrum including IR

The Astronomik H-alpha 12nm XT Clip-Filter EOS M XL (8h11j0) is ideal for imaging hydrogen nebulae from light-polluted and dark observation sites. This filter provides total suppression of emission lines from artificial sources such as mercury and sodium-vapor from street lamps, making it an excellent light pollution filter! Thanks to the high optical quality of the Astronomik MFR substrate, this extra thin clip-filter delivers sharp and crisp star shapes all the way to the edge of the frame. This filter is made to Astronomik's exacting standards and is guaranteed to provide 90% transmission or more at H-Alpha (656nm). The exact transmission ratings may vary between each filter, and the specific T-Max will be listed on the filter case.

Astronomik XT Clip Filter System
The new Astronomik XT-Filters are specifically designed for astrophotography with wide-angle lenses, delivering sharp and crisp star images all the way to the edges of the image, even when using very short focal length lenses. The new Astronomik XT-Filters are coated on an extremely thin substrate of only 0.3mm thickness, significantly reducing aberrations and correcting stars shapes in the outermost corners of the image. Despite the reduced thickness, the Astronomik XT-Filters maintain the highest optical quality: they are finely polished, free of any striae, residual stresses, and bubbles, and are suitable for the most advanced imaging applications. The Astronomik XT-Filters are manufactured using the same durable coating technology as all Astronomik filters. They are extremely scratch-resistant, unaffected by high humidity, and do not degrade over time.
