Description

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.
