High quality objective - filters for observing photographing the Sunspots, Solar Partial Eclipses, transit of Mercury and Venus with binoculars, spotting scope, telescopes and cameraBase 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 filters. 3) Gives neutral white image of the Sun without any colour, against a black background skyAstro-Solar filter is a very flexible substance by nature. When mounted in the filter cell, it will be quite wrinkled. Dont be upset by the appearance because the best resolution is obtained when the material is slightly relaxed or wrinkled
