Photographic Grade Solar Filter
Not for visual use
This AstroSolar material is photo grade, and bright enough for eyepiece projection photography of the sun.
Baader Planetariums AstroSolarTM safety film is a specially manufactured streak- and blisterfree foil. It attains the optical performance of planeparallel glass filters. The base material is not "Mylar"!. The basic development of this film was made in laboratories for nuclear- and particle physics.
High density coatings on both sides of the foil ensures a highly uniform filtering, while neutralizing the occasional miscroscopic holes in the coating. The image of the sun is extremely contrasty and of almost neutral colour.
WARNING - THIS MATERIAL IS FOR PHOTO USE ONLY AND NOT VISUAL. ATTEMPTING TO OBSERVE THE SUN BY LOOKING THROUGH THIS FILTER MATERIAL CAN RESULT IN SEVERE EYE DAMAGE OR EVEN BLINDNESS.
