To observe the Sun directly during the partial phases of an eclipse, either with the naked eye or an optical instrument, it is vital to use adequate filters that are designed for solar observation.
Unless you are familiar with these filters, the Planétarium suggests that you project the Sun’s image onto a screen instead. This method offers a considerable advantage: It allows several people to see the eclipse simultaneously. However, no matter which method you choose, children should only observe the Sun under an adult’s supervision.
