About
An Ultra High Contrast filter passing the OIII and H-beta lines at near 100% while blocking sodium and mercury street lighting and natural airglow, lifting gaseous and planetary nebulae out of the sky background. The XT version is coated on a very thin substrate to keep stars sharp into the corners with wide-angle lenses. Clip-in for Canon EOS APS-C bodies.
