Baader Solar Filters

Baader Planetarium solar filters cover safe white-light observing and more advanced solar imaging. AstroSolar film filters fit telescopes, binoculars and spotting scopes, and the Cool-Ceramic Safety Herschel Prism offers a high-contrast white-light view for refractors.

For narrowband work, D-ERF energy rejection filters protect H-alpha systems on larger apertures, while the Solar Continuum and Calcium GEN-II filters bring out granulation and active regions. A Digital Solar Filter OD 3.8 is available for imaging.
