Place
a pair of binoculars in an open window in the direct path of the sun’s rays.
Stand
a mirror in front of one eyepiece so that it throws an image of the sun on to
theopposite wall of the room. Adjust the mirror until the image is sharp, and
darken theroom.You would risk damaging your eyes if you looked directly at the
sun throughbinoculars, but you can view the bright disc on the wall as large
and clear as in themovies. Clouds and birds passing over can also be
distinguished and. if the binocularsare good even sunspots. These are a few hot
areas on the glowing sphere, some so bigthat many terrestrial globes could fit
into them. Because of the earth’s rotation, thesun’s image moves quite quickly
across the wall. Do not forget to re-align thebinoculars from time to time onto
the sun. The moon and stars cannot be observed inthis way because the light
coming from them is too weak.
