Baader AstroSolar Sun Eclipse Glasses [BA-GLASSES]

Baader: Baader AstroSolar Sun Eclipse Glasses
Baader AstroSolar solar eclipse observing glasses are made using the highly regarded Baader AstroSolar™ safety film. This foil is CE-tested and reduces the intensity of sunlight by 99.999%.
Baader AstroSolar™ film

With AstroSolar™ the Sun appears in its real colour - neutral white. Other films and most 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 its neutral colour balance, AstroSolar enables the use of various colour (or interference) filters which allows the observer to concentrate on certain spectral passbands for investigations of different layers within the solar 'atmosphere'.

Eye safety

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! 

Important Never view the Sun without a suitable Solar Filter!  Solar observing is dangerous and can be hazardous to eyesight. Safety is everyone’s responsibility - please read the safety notes supplied with the product carefully.
