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.

Solar filters for my Nikon and Canon camaras

I bought this solar film to make my own filters for my camaras for taking photos of the sun.
The film is very easy to cut to size, with care not to crease and keeping fingers off the silver side once the backing has been removed and also making sure you dont damage with scratching or pin holes not good for your eyes or camera Viewing the sun looks pure white. My order was delivered with in two days and was well packed and protected from getting bent in the post. . 5 stars
Works very well, good instructions

Follow the instructions carefully and you'll have a great filter. My first viewing showed up sunspots very clearly. The neutral-white sun contrasts well with the black 'sky'. Make the most of the rare sunshine of the UK!
