Baader 7,5nm Solar Continuum Filter (540nm)

Baader 7.5nm Solar Continuum Filter (540nm) (various versions available)

Neue Baader Solar Continuum Filter – now with 7.5nm FWHM

Compared to the previous model with 10 nm half-band-width, the new Baader Solar Continuum Filter has a half-band-width of only 7.5 nm, which once again significantly increases the contrast. This replaces both the previous 10 nm Solar Continuum filter and, for the first time, the stacked 1¼" filter #2458392.

  • Baader 7.5 nm Solar Continuum Filter, CWL 540nm
  • A must for owners of achromatic refractors. This narrowband-filter cuts the spectral range where lens optics draw sharpest and contrastiest. The Baader Solar Continuum Filter lets you use the full power of your telescope.
  • Enhances contrast and reduces the effect of atmospheric turbulence (in combination with white light solar filters)
  • Enormous contrast gain in monochrome photography even on apochromatic systems
  • Important note: The Solar Continuum Filter must be used ONLY with additional filtering (e.g. Baader Herschel prism or AstroSolar Safety Filml)
  • Der Baader Solar Continuum Filter darf NUR mit zusätzlicher Filterung (z. B. Herschelprisma oder AstroSolar Sonnenfilterfolie) eingesetzt werden.
