Baader AstroSolar™ filmWith 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 safetyAstroSolar™ 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.

Perfect for homemade solar filter Monday, 27 April 2020 | Philip
Before you do anything READ the intructions and read them again and take heed of all the warnings, they are there for a purpose.
If you plan to make your own solar filter then this paper is essential. Full instructions on how to make a filter are included, there are also other methods available online. You only get one sheet, so in reality if your scope is 127mm or over you'll only get one chance to make a filter. The paper is very fragile so take your time and be very careful not to damage it. It will be worth it though, the views of the sun are stunning. Delivery was very quick and well packaged.

After reading instructions which you must do making the solar filter was very easy I made mine different to the one shown only because I wanted a deeper filter to slide on the OTA so no need for tape or elastic bands.
Great product and fast delivery.
Baader AstroSolar Safety Film Tuesday, 16 April 2019 | Gordon
Recently Purchased a new Sky Watcher Sky Travel 120 in replacement for the 102 I sold, so thought I would turn my attention to our nearest star, the Sun !
The film came at the same time as my new scope so I did my Blue Peter stuff today and made up the Filter. After the glue had dried I hit the
patio taking a look at the sun. WOW - What a sight, and bonus, One huge Sun Spot.
This stuff really works, suggest you get some to add to your abilities to view whats out there.

Solar filters for my Nikon and Canon camaras Thursday, 22 March 2018 | Steven
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 Wednesday, 10 August 2016 | Steven
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!
