Baader Solar Continuum Filter, 10nm / CWL 540nm
- A must for owners of achromatic refractors. This filter cuts the spectral range transmitting a specific spectral range around 540nm, completely cutting out blue and red wavelengths in an area of the lens system that where the optics are at their sharpest.
- Enhances contrast and reduces the effect of atmospheric turbulence.
- Planeoptically polished, non-ageing sealed coating edges.
Please Note: For safe use, the Solar Continuum filter must be used in conjunction with a primary solar filter (ie, Baader AstroSolar Film). It must be placed after the primary filter, and cannot be used alone, or permanent eye and equipment damage will result.
