Product Overview
Specifically designed for photographing and viewing the sun and solar eclipses through an optical device such as telescopes, binoculars, or camera lenses, this 7.9x11.8" sheet of Baader AstroSolar White-Light Safety Film 5.0 from Alpine Astronomical filters the sun's intense light to a safe level and blocks harmful ultraviolet (UV) and infrared (IR) radiation. Viewing through the film reveals solar surface details including penumbral detail, solar granulation, and lighter-colored faculae. The film improves sharpness and contrast while showing the sun in its proper white color, instead of the orange/red or blue tint common with broad-band filters which filter a portion of the visible spectrum and inhibit observing fine details. Also, since the entire spectrum is being passed through, the use of secondary filters is possible to selectively observe specific bands or highlight targeted solar features.
Use of this filter is intended only for the front apertures of telescopes, binoculars, spotting scopes, and camera lenses, and shouldn't be used without an optic for direct solar observation. Learn how to fabricate custom filter mounts at the manufacturer website.
SAFETY FIRST: Observing the Sun without the proper protection may result in serious personal injury, including permanent eye damage and blindness, and/or damage to equipment. Never point an optic at the sun without an approved solar filter on the front of the optic. For direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder, ensure your filter is ISO 12312-2 (also written as ISO 12312-2:2015) certified. Never use photographic neutral density filters for direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder.
