BAADER ASTROSOLAR CLEARWHITE SAFETY FILM OD 5.1

Baader AstroSolar ClearWhite OD 5.1 Safety Film is highly precise double-metallized solar neutral density filter film and is available in sheet form for DIY construction.

Like the previous OD 5.0 AstroSolar film, this is the only solar film material which does not degrade the optical wavefront, thus allowing high magnification observation without reduction in sharpness or contrast. AstroSolar film produces a natural white solar image without false blue or orange colour.

The film has an optical density of OD 5.1 and reduces the intensity of sunlight by approximately 99.9992%, corresponding to a reduction factor of about 125,000. It complies with the applicable transmittance requirements of EN ISO 12312-2:2015 for filters intended for direct observation of the sun.

Compared to the previous AstroSolar Safety Film OD 5.0, the new ClearWhite version provides an even clearer, whiter solar image along with a slightly higher optical density. Sunspots, granulation, and fine structures of the photosphere can be seen sharply and richly contrasted when used with suitable optical equipment.

The AstroSolar Safety Film is suitable for safe solar observation and photography and is available in a huge range of sizes to fit almost all telescopes, binoculars and telephoto lenses. It comes with a handy template with many common telescope diameters, making it easy to create a perfect-fitting filter.
