Filter Baader AstroSolar photo film OD3.8 20x30 cm

AstroSolar Photo Film (imaging only) 20x30cm, telescope quality, Optical Density OD = 3.8

Digital solar imaging at highest magnifications and short exposure times. Not suitable for visual observation

This highest precision film consistently produces strehl ratios of 94 to 96 percent at interferometric tests ? thus it performs optically like a Fluorite Triplet Lens by Carl Zeiss or Astro Physics

AstroSolar Photo Film OD 3.8 is only intended to be used by well-experienced Astro-imagers. This material is not intended to serve for protection during visual solar observation.
