Telescope Solar Filter Sun Film Astronomical Telescope Accessories for Observing Solar Eclipses

Feature: 1. The Essence of Solar Film: It is actually a solar filter, but different from a solar filter. Astronomical telescopes must be equipped with a filtering device to observe the sun. Otherwise, it may damage the eyes and instrument. The brightness of the sun is extremely high, and even with the addition of a solar film, it is easy to find the sun in the mirror. 2. PET Coated Aluminum Foil Film: Defined as the solar film, this type of solar observation film is called the solar film by astronomy enthusiasts, and is referred to as the solar film in the industry. The name solar film only represents a product that can be used for visual observation with the naked eye and also for astronomical photography. 3. 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 taking photos, without being afraid of wind and rain. When the film is dirty, you can easily use a clean cloth or tissue to clean it, and even wash it with water without any problem. 4. Reducing Light and Radiation: While reducing light and harmful radiation, the solar film does not reduce the contrast of the subject. In other words, using the solar film as a solar filter can achieve better image quality and even easily record sunspot activity on the solar surface. 5. Upgraded Solar Film: The second generation solar film is a thin film material with bright silver color on both sides. Made a thickened design for a safe and solid observation experience. The solar filter film that complies with ISO standards can protect your eyes when observing the sun. If there is any pre use leakage of the solar film, please stop using it immediately.
