Filter Baader AstroSolar safety film A4

With the Baader Astro Solar Foil ND 5,0 - 20x30cm, you can watch and capture the sun with full contrast. It offers also better protection against UV rays than simple glass filters. With the bypacked manual, everyone can build hisher own filter for the astronomical telescope within minutes. The Baader Astro Solar Foil has been awarded as the astro product of the decade in the USA. The following characteristics have made this possible: Optimal protection:The foil is covered on both sides with a filter layer, not only on one side. Every layer can contain micro-holes that bypass UV rays. With a layer on both sides, this is not possible any more. Exceptional optical quality:The Astro Solar foil as an optical performance that is superior to e.g. Mylar foils. This is proven by an independent test. Compared with glass filters, the Baader foil is superior, too - in every section, it has a diffraction-limited performance. What is more, the foils is colour neutral. It does not give a green or yellow colour. Very rigid:A glass filter may break and a foil may rip. But the Baader Astro Solar Foil is, becaus of its special molecular structure, extremely rigid. The colour of the sun through the foil The sun is depicted in a neutral cool white tone. It is a tale that the sun would appear in blue. The neutral tone allows views full of contrast and is described by many observers as 'very pleasant'. Especially at higher magnifications, this allows successful observations.Some astronomers prefer a warm orange or yellow colur. This colour does not represent the reality and is - from our point of view - not optimal for maximum contrast and finest details, but in combination with this neutral-colour foil, one can experiment with differnt colour filters and can choose the best. Thus you are not fixed to one colour. ?
