Become an astrophotography enthusiast's ally with the AstroSolar ECO-Size Safety Film, specifically designed for visual solar observation and high-resolution solar imaging. This premium quality film, measuring approximately 140 x 155 mm, comes complete with do-it-yourself instructions and a cutting template, ensuring a custom fit for your telescopic equipment. Crafted for telescope quality performance, the AstroSolar Safety Film boasts an Optical Density (OD) of 5.0, making it exceptionally safe for visual solar observation when used in conjunction with additional optics, and for capturing stunning solar images. Its high optical density ensures that it blocks out a significant amount of sunlight, providing a safe and clear view of the sun's surface.

The precision of this film is unparalleled, consistently achieving strehl ratios between 94 to 96 percent in interferometric tests. This level of performance is comparable to high-end Fluorite Triplet Lenses from renowned manufacturers like Carl Zeiss or Astro Physics, ensuring that you don't compromise on sharpness or contrast even at high magnifications. With a legacy spanning over 25 years, the AstroSolar ECO-Size Safety Film is the only solar filter material on the market that maintains the integrity of the optical wavefront. This means that even when paired with long-range optics, the film allows for high magnification without degrading the image quality of the solar surface.

This film is crafted from the same high-grade material as the proven AstroSolar Safety Film 5.0 in A4-size. Due to popular demand, it is now available in a more compact and economically priced ECO-size. It's an ideal choice for outfitting small telescopes, finders, binoculars, spotting scopes, and camera lenses with a professional-grade solar filter. Whether you're a seasoned astronomer or a photography enthusiast looking to safely explore the sun, the AstroSolar ECO-Size Safety Film is an essential tool for your observational and imaging arsenal.
