Astromania Deluxe Solar Filter 100mm Adjustable Metal Cap for Telescope Tubes with Outer Diameter from 70mm To 92mm Aperture 75mm

Baader AstroSolar Safety Film
 

Our complete line of Safety Film Solar Filters feature renowned Baader AstroSolar Safety Film in a sturdy, clear-anodized aluminum cell. The high-quality polymer film material is metallized on both sides with an ion-deposited coating to form a safe barrier against all but 0.0001% of incoming sunlight to provide a clear, crisp view while rejecting harmful ultraviolet and infrared radiation.

With exceptional resolution and superior contrast
 

With exceptional resolution and superior contrast compared to Mylar and other solar filter materials, Astromania Solar Filters display a natural, neutral white view of the Sun's surface, without artificial tinting. Once attached to a telescope, these filters provide sharp, scatter-free views of sunspots, solar eclipses, planetary transits, solar granulation, and even white filamentary faculae - the latter of which cannot be seen with most other solar filters.

Can be used in tandem with various color eyepiece filters
 

Due to their neutral color balance, Astromania Safety Film Solar Filters can be used in tandem with various color eyepiece filters to accentuate certain spectral passbands for telescopic studies of different layers within the solar "atmosphere".
