Description
- AstroSolar Photo Film (imaging only), 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.
