This family of solar filters is made in the most elaborate way. AstroSolar must not be put under stress, neither during mounting of the film, nor during any temperature change. For this reason the ASTF-Filter features a temperature compensated cell. The film itself is repeatably cemented onto an injection molded ring, whereas the substrate of that ring has the same thermal expansion like the AstroSolar Filter material itself. This free floating film-carrier ring is held onto the aluminum frame with the help of another holding ring made of fiber reinforced plastic – for a maximum of security against breakage of the cell. This temperature compensated cell enables the AstroSolar filter material to retain its excellent optical quality at any temperature – be it -30°C or +50°C
NOTE: SCT Users must only mount the filter to the Outside of the Tube (the limited depth of the SCT front ID prevents adequate engagement of the centering bolts)

After 15 years of offering AstroSolar film sheets as a DIY-product, this system of Baader Solar Filters™ is designed to retain the true optical quality of the diffraction limited AstroSolar Safety Film.
Baader Solar Filters provide a professional and secure solution to observe and image the Sun using AstroSolar Safety Film. Many ready-made filters stretch the filter material like a drumhead in order to make it look like a piece of glass – this absolutely estroys the image quality, rendering the film useless for high magnification work. AstroSolar must be mounted entirely stress free in order to perform like a high precision planeoptical window. It sounds like a contradiction with the traditional perception of quality, but AstroSolar must show slight ripples! When the film is put under stress by an improper cell mount its optical quality is degraded and it tehn performs just like a common coated glass-filter made of untreated floatglass.
With AstroSolar™ the Sun appears in it’ s real color – neutral white. Other films and most glass filters produce a blurry bluish, yellow-orange, 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.
Baader Solar Filters are available in 3 types; ASTF - AstroSolar Telescope Filter, ASSF - AstroSolar Spotter Filter, and ASBF - AstroSolar Binocular Filter. With a total 21 sizes, there is a Baader Solar Filter available to fit practically every Telescope, Spotting Scope and Binocular.
