    Baader Solar Continuum 1.25" 7.5nm Filter CWL 540nm

    The new Baader Planetarium 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 is 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. As a monochromatic filter, the filter is best to use on monochromatic cameras and can even provide a tremendous gain on pure color systems

    Please note, the Solar Continuum Filter may be used for purely VISUAL observation ONLY in conjunction with the Baader Herschel Prism or with the Baader AstroSolar Safety Film OD 5.0. For photography, you must use AstroSolar Photo Film OD 3.8.
