The filter cell that holds the Baader AstroSolar film is constructed from lightweight, 18 gauge aluminum and is powder-coated white. The heavy duty threaded inserts and nylon thumbscrews will insure a secure fit on the front of your telescope's optical tube assembly.
Astrozap Baader Solar Filter for 11" SCT Telescopes
With Baader AstroSolar film, the Sun will appear a neutral white, allowing you to see more detail, especially in the faculae regions, than competing solar films that produce a bluish or reddish image. Due to its 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."
The Astrozap Baader Solar Filter is essentially free from pinholes, since it is coated on both sides. This means that your chance of two pinholes overlapping each other would be extremely faint. 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!

Product QuestionsOne more question: What are the advantages/disadvantages between the front tube solar filter and an eyepiece solar filter. Does the front tube filter somehow obstruct possible solar heat damage to the corrector or mirror?-ThanksQuestion by: Gus Alba on Mar 9, 2016 6:59:00 AMEyepiece solar filters should never be used - period! They are dangerous and focus light at hundreds of degrees C against a piece of glass which could crack at any moment and blind you. Only front mounted filters are safe for obstructed optical systems. Rear solar filters like Herschel Wedges or Ha scopes are safe in smaller refractors, but eyepiece filters are never safe.Answer by: Chris Hendren (Admin) on Mar 11, 2016 4:45:00 PMHi Chris,
Firstly, congratulations on your APOD image - stunning, mate! I'm considering a white light solar filter for my 11" Edge HD. As far as contrast, clarity, etc., would you recommend a full-coverage Baader filter or a 2-3" aperture filter? Appreciate your thinks. Steve S. in ColoradoQuestion by: Steve Solon on Oct 5, 2016 8:01:00 PMHello Steve, thanks! Sorry for the delay in answering this.
I would recommend the full aperture filter. It will give you better resolution on sunspots and surface granulation. You may want to consider a solar continuum filter at your eyepiece or camera for better contrast.Answer by: Chris Hendren (Admin) on Oct 28, 2016 2:12:00 PM
