Use the new Baader Planetarium Calcium K-Line Filter to image the sun in K-Line with any telescope.
Baader’s double-stacked filter uses sophisticated coatings to produce a sharp 8nm wide bandpass, centered at 395nm.
This bandpass provides ample contrast for high-resolution imaging of super granulation, flares, and other features that are prominent in CaK.
Unlike small, dedicated, and expensive CaK telescopes, the Baader K-Line filter works with your existing telescope at a fraction of the cost.
The Baader CaK may be used with virtually any telescope, of any aperture – Newtonian, SCT or Refractor.
A 200mm x 290mm (8″ x 11″) sheet of Baader AstroSolar Photo Film (ND=3.8) is provided with each filter.
