Astrozap Solar Filters made with Baader AstroSolar™ film feature mount rings constructed from lightweight 18Ga. aluminum and powder coated white. Heavy duty threaded inserts and nylon thumbscrews insure a secure fit. Baader AstroSolar™ film is CE / ISO certified: conforms to and meets the transmission requirements for eye safety: EN ISO 12312-2:2015.

With AstroSolar™ the Sun appears in neutral white. Other films and some glass filters produce a blurry bluish or reddish Solar image, thereby cutting part of the spectrum. Especially with an orange sun, it is very hard to see faculae regions which are visible predominantly in the blue wing of the spectrum.

Due to it's neutral color balance, AstroSolar enables the use of various color (or interference) filters which allows the observer to concentrate on certain spectral passbands for investigations of different layers within the solar "atmosphere".

AstroSolar™ is essentially free from pinholes, since - other than with 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!

Please follow the following safety precautions:
1. Never point your telescope at the sun without a proper filter. 2. Always inspect the filter before placing it on your telescope prior to observing to ensure that there are no defects (scratches or pinholes) that could damage your eyes or equipment. If you discover any defects, do not use the filter. 3. Only use the filter mounted on a telescope.
