Baader AstroSolar Safety Film

This Baader AstroSolar Safety Film is A4 sized, measuring 200mm x 290mm. It's a specially manufactured streak-and-blister-free foil, without Mylar! 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. The performance of AstroSolar is even more remarkable when considering its very low cost - only $36 for telescopes up to 8". We even have sizes large enough for producing full-aperture filters for very large telescopes (see the huge 40" filter as shown above!). When combined with Baader's tips for a simple do-it-yourself filter mount, anyone can construct a complete low cost - High Quality - white light solar filter for any telescope.

It is possible to further improve the stability and sharpness of the solar image through the use of the Baader Solar Continuum Filter. Views of granulation and faculae are particularly enhanced through the use of this filter, in combination with AstroSolar. Users of achromatic refractors will be particularly pleased with the performance using this additional filter.

This precision film was made in laboratories for nuclear and particle physics, and - due to its absolute homogeneity - the foil attains the optical performance of high quality plane-parallel glass filters.
