Feature●The essence of the solar film: it is actually a solar filter, but different from a solar filter. Astronomical telescopes must be equipped with a filter device to observe the sun. Otherwise, there may be damage to the eyes and instrument. The brightness of the sun is extremely high and even with an additional solar film, it is easy to find the sun in the mirror.●PET COATED ALUMINUM FOIL FILM This kind of solar observation film is called "solar film" by astronomy enthusiasts and referred to as solar film in the industry. The name solar film is merely a product that can be used for visual observation with the naked eye and also for astronomical photography.●Advantages of solar film: the solar film looks at the red and yellow sun. The advantage is that the solar film is not easily damaged and is suitable for long-term use in natural environments, especially when photographing, without fear of wind and rain. If the film is dirty, you can easily clean it with a clean cloth or tissue and even wash it with water.●REDUCTION OF LIGHT AND RADIATION While the solar film reduces light and harmful radiation, it does not reduce the contrast of the subject. In other words, by using the solar film as a sun filter, you can achieve better image quality and even record the sunspot activity on the suns surface easily.●Upgraded Solar Film The second generation solar film is a thin film material with bright silver color on both sides. Thickened design for a safe and solid observation experience. The sun filter film complies with ISO standards can protect your eyes when observing the sun. If there are leaks of the solar film before use, please stop using immediately.Description
