The Baader Solar Continuum Filter is practically a narrowband photosphere filter for solar observation in white light and provides the highest contrast.

• Baader 7.5 nm Solar Continuum Filter, CWL 540 nm, in cell with 1.25" screw-in thread
• A must for owners of achromatic refractors. This narrowband-filter cuts the spectral range where lens optics draw sharpest and contrastiest. The Solar Continuum Filter brings power back to you.
• Enhances contrast and reduces the effect of atmospheric turbulence (in combination with white light solar filters)
• Enormous contrast gain in monochrome photography even on pure color systems - see second and third image
• Important note: The Solar Continuum Filter must be used for purely VISUAL solar observation ONLY with additional filtering (e.g. Baader Herschel prism or AstroSolar Safety Filml)
