Baader 1.25" (31.7mm) Calcium K-Line Filter sold together with ND=3.8 AstroSolar 200x290mm Photo Film

 

The New Baader Planetarium Calcium K-Line Filter makes imaging of the sun in K-Line accessible to anyone with a telescope and digital camera or webcam. Baader's innovative double-stacked filter uses sophisticated coatings to produce a sharp 8nm wide bandpass, centered at 395nm.

Please note: this filter is intended for imaging only. It will not be safe for visual use. It must also be used with a safe pre-filter and therefore includes A4 sheet of Astrosolar (PHOTO D=3.8).

Never use any eyepiece filter for solar observation without objective front filter!
