"Baader Planetarium's AstroSolar Safety Film delivers white light views of the Sun that are unmatched by any other objective solar filter or material. The views through AstroSolar display fine solar details, including fine penumbral detail, solar granulation and lighter colored faculae. The disk is set against a dark background, free of the haze and scatter that is common in typical 'mylar' films or inexpensive glass filters. Note: This foil is intended for solar viewing with optical instruments (telescopes, binoculars, cameras). AstroSolar Safety Film 5.0 is not authorized to be used for naked eye solar observation or production of solar viewers.
