For those who approach sun observation with caution, the 140x155mm Baader AstroSolar White-Light Safety Film 5.0 offers a reassuring solution. This film is specially crafted to make observing and photographing the sun through telescopes, binoculars, or camera lenses not only possible but also completely safe. It meticulously reduces the sun's brightness to a comfortable level, while also blocking harmful ultraviolet (UV) and infrared (IR) radiation, ensuring your eyes and equipment are protected.

Viewing the sun's surface through this film reveals an array of fascinating details such as penumbral shadows, the intricate pattern of solar granulation, and the brighter areas known as faculae. This enhancement in sharpness and contrast comes with an added bonus: the sun is shown in its natural white color. This is a significant advantage over other filters that may alter the sun's color, potentially obscuring some of the finer details.

Furthermore, the film's broad, full-spectrum bandpass allows for the use of secondary filters. This means you can explore specific wavelengths or focus on particular features of the sun, tailoring your viewing experience to your interests.

In essence, the Baader AstroSolar Film is an invaluable tool for anyone interested in solar observation. It provides a safe, detailed, and true-color view of the sun, enhancing both the enjoyment and the educational value of your observations. Remember, safety is paramount when observing the sun, and this film ensures that you can explore its wonders without any risk.

The patented Baader AstroSolar® Safety Film 5.0 is produced for visual and photographic solar observation at high magnification (with additional optics). AstroSolar® Safety Film is best suited for precision work with all astronomical telescopes and binoculars – just as well as for all photographic camera- and tele-lenses (Patent pending in all European States - voted for "Astro-Product of the Decade" in the USA, and Sky and Telescope's Sept 2000 Review "A New Standard in Solar Filters") Baader Planetarium's AstroSolar®Safety Film delivers white light views of the Sun that are unmatched by any other objective solar filter or material. The views through AstroSolar display fine solar details, including fine penumbral detail, solar granulation, and lighter colored faculae. The disk is set against a dark background, free of the haze and scatter that is common in typical 'mylar' films or inexpensive glass filters. The performance of AstroSolar is even more remarkable when considering its very low cost -for telescopes up to 8".When combined with Baader's tips for a simple do-it-yourself filter mount, anyone can construct a complete low cost - High Quality - white light solar filter for any telescope.

It is possible to further improve the stability and sharpness of the solar image through the use of the Baader Solar Continuum Filter. Views of granulation and faculae are particularly enhanced through the use of this filter, in combination with AstroSolar®. Users of achromatic refractors will be particularly pleased with the performance using this additional filter.

NEW - AstroSolar® Eco size. This smaller 140x155mm size is ideal for smaller refractors (<4.5"), Camera Lenses, Spotting Scopes and Binoculars. Included is a DIY cell that enables you to create a functional hi-resolution filter with simple materials.
