How to observe a solar eclipse, how to see a solar eclipse The correct way to watch a solar eclipse

Yes, even wearing sunglasses is risky.

1. Pay attention to several wrong ways to observe a solar eclipse (or sun) and tell others to keep them safe. The eclipse should never be seen through binoculars, telescopes, glasses of any kind, sunglasses, smoked glass, space blankets, CDs, polarizing filters, or colored film. They do not protect the eyes.

While they block wavelengths of light that are visible to the naked eye, it is light that is invisible to the naked eye that harms the eye. Ultraviolet and infrared rays still pass through these objects, causing as much damage as visible light.

2. Use a sun filter. If you choose to look at the sun directly instead of projecting it onto other objects, you need to place a solar filter in front of your eyes. While it may be possible to observe a total solar eclipse without any precautions during a total eclipse, only an experienced observer will be able to determine exactly when it is appropriate to see with the naked eye and when to immediately block the solar filter before the sun reappears.

Most solar eclipses are partial solar eclipses, and most observers are novices, so it's best to only look through a solar filter**, which is safer. A flash of sunlight can also damage your eyesight, so even if % of the sun is obscured, it is dangerous. There are sun filters for a variety of observation devices (cameras, binoculars, and monoculars) on the market.

3. Make a solar eclipse projection device or a small hole instrument. They are easy to do, and are the easiest and safest way to observe a solar eclipse, with little to no money other than a few posters. The disadvantage is that the projection image of the sun is very small, but it is suitable for children and teenagers who enjoy the process of making and using the small orifice instrument.

4. Observe the eclipse with a projection device. Projecting an image of a solar eclipse through binoculars or monoculars is also another safe way to observe a solar eclipse indirectly. However, it is only safe to project with a telescope, rather than directly observing the eclipse.

Don't look at a solar eclipse directly through a telescope projecting the sun!

5. Use goggles for electric welding. Through the welder's goggles with shading number 14, you can observe the sun with the naked eye. This is the most affordable and readily available filter.

The goggles must completely cover both eyes for the entire duration of the observation. You can also place it in front of the binoculars objective. You have to cover all the lenses with goggles, and if you can only cover one, then cover the other lens with a cover.

6. Install the filter. This method is more expensive and is mostly used by enthusiastic astronomy amateurs, or those who have a similar hobby and are willing to spend money on expensive equipment. There are monoculars and binoculars with their own solar filters on the market, but they are very high.

Unless you're watching the heavens as a lifelong hobby, consider buying one. You can also just buy filters and mount them yourself on monoculars and binoculars.

1. Do not use the naked eye or optical equipment to observe directly, **Total solar eclipse, first of all, pay attention to one point: never use the naked eye or any optical equipment (such as telescopes, etc.) to look directly at the sun! This is not just a suggestion, but a very serious warning.

If you look directly at Pipsqueak with the naked eye, the sun's rays will not only make it impossible for you to observe at all, but will even burn your eyes. When the optical device observes, because the magnifying glass in the optical device focuses the sunlight to a small point, the energy of this point is considerable, which may damage the observer's retina, and even cause blindness in both eyes. The retina does not feel pain, so it is especially important to note that you will not notice it even if it burns out.

When observing, it is best to use eclipse glasses that filter out dangerous light. Observe for about 3 minutes and let your eyes rest, which is safer.

2. Be aware of the potential dangers of optical equipment, and do not place your hands or any flammable objects near the eyepiece when using the optical projection method to observe the eclipse. Focused sunlight can easily cause fire or damage. At the same time, the telescope must be cooled down from time to time, and the eyepiece may be too hot and the lens may crack when working in the sun for a long time.

3. Pay attention to your physical condition to prevent heat stroke, the temperature is high in summer, and you are at risk of heat stroke if you stay outdoors in the sun for a long time. In addition, if you keep looking up at the sun for a long time, the blood flow in your head will lag, and your physical condition may deteriorate. Prepare a hat and cold drinks when observing, and rest in the shade from time to time, etc., the most important thing is to protect your body.

Ways to observe a solar eclipse:

1. Look with a filter. The material used to make the filter can be waste film, or it can be made of broken computer floppy disk core.

2. Look at it with black glass. Candles are used to blacken pieces of glass, which can be used to watch a solar eclipse.

3. Look at it with a basin. Drop an appropriate amount of ink in a basin of water, make black water, and watch the eclipse through the reflection of the sun.

4. Small hole imaging. Using two boards, dig a small hole in one of the boards and let sunlight shine through the small hole in the hood and onto the other board.

5. Shade observation method. During a solar eclipse, the gaps in the shade of the trees will form small natural holes, and the small bright spots under the shade of the trees are all images of the sun's small holes.

6. Look with eclipse glasses. There are special eclipse glasses** on the market.
