When observing the solar eclipse, you should choose sunny areas as much as possible and pay attention to the safety of your eyes. Because the sun's light is one million times stronger than moonlight, it can't be seen directly with the naked eye or through a telescope without dimming equipment, otherwise it will easily cause retinal damage and even blindness. It is safer to wear a pair of eclipse observation glasses during the partial solar eclipse. When observing the solar eclipse with a telescope, you must add a filter in front of the eyepiece or detector to avoid burning your eyes. During the total solar eclipse, you can watch it directly with the naked eye. Before shooting with a telescope, you should take a dimmer or filter.

You can also take the following methods:

1. Look with welding goggles.

Welding goggles should protect your eyes in strong light, so you can wear them to look at the sun directly.

Advantages: it can be used.

Disadvantages: it's hard to find, but it's still heavy and easy to get tired.

Look at it in a basin.

Drop a proper amount of ink in the basin and turn it into black water. Watch the eclipse by the reflection of the sun.

Advantages: simple and safe.

Disadvantages: the water will fluctuate, and the viewing effect is poor. You need to find pots and ink.

3. Small hole imaging method

Two pieces of white paper, one with a neat round hole, one facing the sun, the other behind the hole, let the sunlight image on the other piece of white paper through the hole.

Advantages: simple manufacture.

Disadvantages: holding the image by hand is unstable and inconvenient to observe. It is recommended to support two pieces of hard paper with brackets.

4. Shadow observation method

During the solar eclipse, the gaps in the shade will become natural holes, and the small bright spots in the shade will be imaged by the small holes in the sun. During the solar eclipse, you can see those small bright spots from round to deficit, and each small bright spot is a small solar eclipse image. On the ground, on your arm, on the dog walking beside you, these small eclipse images are all there.

Look at it with eclipse glasses

There are many total solar eclipse glasses on Taobao. Among them, Bader membrane is the best.

6 telescope projection method

Don't shake your hands, or the shadow of the sun will run back and forth. Never look directly at the sun with a telescope. If you look at the sun directly with a telescope, you must use a filter.

Observe with a camera

Note that if there is no filter, observing the solar eclipse directly from the viewing frame will also hurt your eyes. Don't try. It is best to use a tripod when shooting. If you want to get a clear image of the solar eclipse, you need a telescope.

8. alternative method: listen to the solar eclipse with your ears

Because the ionosphere of the earth will change greatly during the solar eclipse, the solar eclipse can be "heard" through the change of signal intensity of short-wave amateur radio stations. You can also "listen" to the eclipse through the general radio: listen to the short-wave radio in the eclipse area and "listen" to the eclipse. Ideally, it is the BPM standard time standard frequency signal from Pucheng, Shaanxi Province, with frequencies of 2.5MHz and 5.0MHz, and its sound will suddenly increase or decrease before and after the solar eclipse. But ordinary people are not interested in this method, and professionals will not use it.

PS: Never take the exposed film to see it, because there are many tiny unexposed spots on the exposed film. During a partial solar eclipse, strong sunlight will directly shine on people's retina through these spots, which may cause permanent damage to eyes! ! !

Baking black glass is not advisable either!

Remember, remember! ! !
