High-quality objective - filte for observing/photographing the Sunspots, Solar / Partial Eclipses, the transit of Mercury and Venus with binocula, spotting scope, telescopes, and camera. Specially CE-tested safety film with high-quality optical characteristics reduces the intensity of sunlight by 99.999%. Astro Solar safety film is a specially manufactured streak and blister-free foil only 0.012mm thick and attains the optical quality of plane-parallel glass filte. The base material is not Mylar. The highly uniform molecular structure of this material is the result of nuclear elementary particle physics. The coating is subject to constant quality control. It?s the reflective property of over 99.999% has been the German Republic Bureau of Standards and Conformity with EU norm 89/686 is certified with CE symbol. It reduces the intensity of sunlight by a factor of over 100,000. The coating on both sides of the foil ensures highly uniform filtering. While neutralizing the occasional microscopic holes in the coating (which are also much more present n glass filte). One layer of this foil is sufficient for the construction of a safe, high-resolution solar filter. The quality of the solar image is immeasurable, better than what can be achieved by using a so-called Mylar ?rescue blankets? or similar materials, which must be used in several laye. Base Astro - Solar is extremely clear and homogenous. It is specially treated 1) To absorb internal reflections (reducing haziness present in other films). 2) To reduce internal stresses which dramatically improve the optical performance over Mylar and similar filte. 3) Gives a neutral white image of the Sun without any color, against a black background sky. An Astro-solar filter is a very flexible substance by nature. When mounted in the filter cell, it will be quite wrinkled. Don?t be upset by the appearance because the best resolution is obtained when the material is slightly relaxed or wrinkled.
