Baader Astro Solar Safety Film 100x50cm Telescope Quality, ND=5.0.

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 coloured 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. We even have sizes large enough for producing full-aperture filters for very large telescopes. 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.

Eye safety:
AstroSolar™ is essentially free from pinholes, since - unlike even the most expensive glass filters - it is coated on both sides, so that the chance of two pinholes overlapping each other is extremely faint. Pinholes do appear, but to 1 out of 10000 only, in optical density 2.5! Baader AstroSolar™ safety film has been approved for eye safety by the National Bureau of Standards in Germany, the PTB. Unlike any other Solar Filter on the market, AstroSolar™ is CE-tested according to EG-Norm 89/686 and EN 169/92 ( notified body 0196). All processes connected to this product have been thoroughly tested. Coatings are inspected constantly for consistency to ensure your eye safety!

*Baader AstroSolar products are appropriately certified for the European Standard for personal eye equipment (EN 1836:2005+A1:2007) and CE certified

The film must be mounted flat and free of any tension - Only this will provide first class optical properties. The quality of this patent pending material is so high that any strain on the film will lead to a very noticeable deterioration of optical quality (it is preferable to have a few mild wrinkles than to place the film under stress from pulling it).
