This is probably the most important part of this website. Never view the Sun with the naked eye or by looking through optical devices such as binoculars or telescopes! This is critical! You may have taken a magnifying glass out into the sun and burned leaves with it. So understand this: you have a lens just like that in your eye.
This literally burns your eye, causing permanent eye damage or blindness. In additional, there are no pain sensors inside your eye—so you won't even know it's happening! If you are now completely terrified about looking at the Sun, good! If not, go back and re-ead the warning above. Called totality , it lasts from a few seconds to a few minutes. The instant the moon begins to move off the Sun's face, you must go back to using safe viewing techniques.
There are safe ways to view the sun. The simplest requires only a long box at least six feet long , a piece of aluminum foil, a pin, and a sheet of white paper. The length of the box is important: the longer the box, the bigger your image of the sun will be.
To estimate how big the image will be, multiply the length of the box by 0. For example, if your box is six feet 72 inches long, your solar image will be 72 x 0. Find or make a long box or tube. If you can't find a long tube, you can tape together two or more shorter ones.
Two triangular shipping tubes, taped together, make a good solar viewer. Cut out the cardboard at one end of each tube and tape those ends together with duct tape, so that light can travel the length of the tube. Cut a one-inch hole in the center of one end of the box.
Tape a piece of foil over the hole, then poke a small hole in the foil with a pin. At the other end of the tube, cut a good-sized viewing hole in the side of the box. Put a piece of white paper at the end of the box, right inside the viewing hole. This is the screen where your projected Sun will appear.
To use your viewer, point the pinhole end of the box right at the Sun. If you have trouble aiming your viewer, look at the shadow of the box on the ground. Move it until the shadow is as small as possible—that is, until it looks like the end of the box, and the sides are not casting a shadow. Do not look through the pinhole at the Sun! Look only at the image on the paper. Use two pieces of cardboard. In one, cut a one-inch hole, then tape a piece of foil over the hole. Now make a pinhole in the middle of the foil.
Use the other piece of cardboard which should be white for best viewing as a screen. With the Sun behind you, hold the pinhole cardboard as far from your screen as you can. The farther the pinhole is from the screen, the bigger your image will be. Use your hands. Hold up both hands with your fingers overlapping at right angles.
The holes between your fingers make pinholes. Use a tree. If you have some shade trees in your location, try looking at the images of the Sun coming through the holes formed by the leaves. Use a piece of white cardboard to capture the images for a great viewing session! Pinhole images are pretty dim and small. Firmly attach the binoculars to a tripod, eyepieces facing down. You can do this with duct tape—what else? Make a Sun shield from a piece of cardboard.
Cut a hole for one of the lenses. Then tape the shield to the front of the binoculars with the lens sticking through the hole. Use duct tape to seal any holes that leak light past the cardboard shield. Point the binoculars toward the Sun while holding a piece of white cardboard about one foot beyond the binoculars. It will take a little effort to find the Sun. Once you do, you can focus the binoculars to bring the Sun to a sharp image.
DO NOT put your hand or anything flammable near the eyepiece. The concentrated sunlight exiting there can cause a nasty burn or set something ablaze! Now you can watch a beautiful, bright, magnified image of the sun as the eclipse proceeds. You will have to adjust the tripod periodically to account for the Earth's rotation. A warning: give your binoculars a cooling break now and then. The eyepiece may become overheated and the lens elements may separate if you leave it pointed at the Sun for too long.
If you feel you must look directly at the Sun, be absolutely sure that you have the correct filter. Just because a filter makes the Sun seem dim does not mean that it's blocking the dangerous, invisible infrared or ultraviolet radiation that will damage your eyes. Do NOT use sunglasses, polaroid filters, smoked glass, exposed color film, X-ray film, or photographic neutral-density filters.
Make sure that the supplier of your eclipse filter is reputable and reliable—a few are listed below. You can purchase them online, and usually at science museum stores in areas where an eclipse is visible.
If you want to use a filter on a telescope, use only the filter supplied by the manufacturer or by a manufacturer who makes the filter specifically for the instrument you are using.
The manufacturers of some inexpensive telescopes supply a welder's glass filter that screws onto the eyepiece. It may heat up and crack as you are looking through the telescope. A proper solar filter always goes on the front end of the telescope, blocking the sunlight before it enters the optical system.
Thanks to the Orion Telescope Center for the loan of this unsafe filter. Orion does not sell these! They just had one around as a bad example. They are good and knowledgeable people. By following the instructions above and using a modicum of good sense, you will be able to enjoy solar eclipse after solar eclipse.

Solar-eclipse-viewing glasses. Thomson Reuters On August 21, the total solar eclipse will race across the continental US for the first time in 99 years.

See the solar eclipse using nature’s pinhole camera, tree leaves
By Anne Buckle and Aparna Kher. One of the easiest ways to safely watch a solar eclipse is to use 2 sheets of cardboard and make your own simple pinhole projector. Never look directly at the Sun without proper eye protection. You can seriously hurt your eyes and even go blind. The simplest and quickest way to safely project the Sun is with a projector made from only 2 pieces of card or paper. A box projector works on the same principles, it requires a little more time and a few extra items to construct, but it is more sturdy. Topics: Astronomy , Eclipses , Sun.
