These custom-made filters utilise BAADER AstroSolar Safety Film, which combines excellent optical properties and Maximum Safety whilst directly viewing the Sun. The film is held in bespoke mountings to fit exactly over the end of the telescope tube for maximum convenience. This foil is CE-tested and reduces the intensity of sunlight by 99.999% (neutral density 5.0).

Baader AstroSolar safety film is a specially manufactured streak and blisterfree foil and is extremely safe to use.  It attains the optical performance of plane-parallel glass filters.  The base material is not "Mylar"!  The basic development of this film was made in laboratories for nuclear and particle physics.  High density coatings on both sides of the foil ensures a highly uniform filtering.  The image of the sun is extremely contrasty and of almost neutral colour.

WARNING: Viewing the Sun directly without suitable safety filtering can cause instant and permanent eye damage or blindness. Please ensure the filter is fitted securely to your telescope and is free from damage before every use.
