The new Baader Solar Continuum filter is designed to enhance the visibility of solar granulation and sunspot details.  By transmitting a specific spectral region around 540nm, free of emission and absorption lines, the Solar Continuum filter is able to boost contrast and reduce the effects of atmospheric turbulence.   With the Solar Continuum filter in place, images snap to focus, and granulation becomes regularly visible.  Details at the limit of visibility become easier to hold, and image motion reduced.

The Solar Continuum filter works well in all types of telescopes, for both visual and imaging.  Users of SCTs and achromatic refractors will find it particularly beneficial, as it completely excludes the red and blue wavelengths, and centers on the peak visual wavelengths where the telescope optics are sharpest and free from chromatic aberrations.  For digital imaging, we also recommend the Continuum filter be combined with the UV-IR Cut filter (to completely cut the defocused far infrared wavelengths). 

IMPORTANT: The Solar Continuum Filter MUST only be used in conjunction with the recommended SOLAR FILTER for your telescope. Failure to do so will result in serious eye damage or blindness.
