What do you need to prepare to watch the solar eclipse?

To watch a total solar eclipse, you need to use special filters or solar eclipse observation glasses to prevent the sun from burning your eyes.

If you want to observe a solar eclipse through a telescope, you must install a Bard film at the front of the objective lens to reduce light. Never point a telescope directly at the sun. Products such as solar eclipse observation glasses or Bader membranes can be purchased at online shopping malls (such as Xinbao or Zoudong). It is recommended to prepare them in advance.

Tips for observing the solar eclipse using the pinhole imaging method:

1. Pinhole imaging-shade observation

Sunlight will pass through the gaps between the leaves. The pores form a mottled pattern, which is the most common small hole imaging, but usually the spots are round and do not attract people's attention. During a solar eclipse, a small bright spot under the shade of a tree shows the incomplete shape of the sun.

2. Small hole imaging - paper tube/cup drilling projection

Cover one end of the paper tube with translucent plastic, open a small hole at the other end, and face the hole toward the sun. The longer the length, the more obvious the effect. You can also use potato chip tubes to make it.
