Matters needing attention in observing annular solar eclipse:

1. Be careful not to observe the sun directly with the naked eye or any optical equipment (such as telescope). If you look directly at it with the naked eye, the sun's rays will not only blind you, but even burn your eyes. When using optical equipment, the magnifying glass will focus the sunlight on a small point, which will damage the retina of the observer and even lead to blindness.

This is very important, because the retina can't feel the pain, so it won't notice whether it is burnt out. It is best to filter out dangerous light with corrosion-resistant glasses. Observe for about 3 minutes and let your eyes rest. It's safer.

2. Pay attention to the potential dangers of optical equipment. When observing the solar eclipse with optical projection, don't put your hands or flammable objects near the eyepiece. Focused sunlight can easily cause fire or damage. At the same time, the telescope must be cooled from time to time, and prolonged exposure to the sun will lead to overheating and fracture of the eyepiece.

3, pay attention to physical condition, prevent heatstroke, high temperature in summer, stay in the sun for a long time, there is a risk of heatstroke. In addition, prolonged exposure to the sun will delay the blood flow to the head, putting the body at risk of deterioration. Wear a hat, drink a cold drink and rest in the shade from time to time. Protecting your body is the most important thing.
