Baader Planetarium Astrosolar Photofilm ND3.8 (20x29cm)

The Astrosolar ND3.8 film is designed for photographic use and provides shorter exposure times of up to 1/1000 sec. It is important to note that it should not be used without an additional neutral density eyepiece filter.

The Astro Solar film has a homogeneous construction, comparable to the optical performance of high-quality plane-parallel glass filters, minimizing light scattering. The double-sided metal coatings ensure uniform density and good color balance across its surface.

• Safety film composition that does not break easily.
• ND-5 absorption factor, allowing only 1/100,000 of visible light to pass through.
• Reflects 99.999% of unwanted light and absorbs all ultraviolet radiation.
• Certified safe for direct solar observation by the German National Station Service.
• Dimensions: 20x29 cm.

The AstroSolar BAADER filters are CE certified and guarantee safe and clear observation of solar activity.
