2017solar.com - First issues DO NOT try to use any kind of optical magnifying device to view the photo voltaic eclipse. Binoculars and telescopes pointed on the solar and seen by the human eye may cause instantaneous blindness. Professionals who use optical devices which have special filters which permit them to view the occasion via their instruments.
Joe Citizen, then again, has a couple of low cost choices that may be just as fun. I will briefly describe the most popular methods. Photo voltaic eclipse glasses purchased from an astronomy store, a homemade pinhole viewing field or the cardboard projection method.
Safe photo voltaic eclipse glasses are made from a scratch resistant, optical density 5, black polymer material. They can take away practically all the infra purple, extremely violet and 99% of the harmful seen mild spectrums. These special Walgreens Solar Glasses permit you to see the eclipse as an orange image. They're low cost, lightweight, and a few manufacturers supply the flexibility to print promoting data if your organization would like to give them away or promote them as promotional items. Even though these glasses are safely rated, specialists still advice not to view the solar via them for prolonged lengths of time. So, use common sense and watch the eclipse for only brief lengths of time.
If you can't find a set of Walgreens Solar Glasses, then your finest guess is to make a pinhole viewer. A pinhole viewer is an indirect method of viewing the eclipse. It is a lot safer than any kind of glasses or filter as a result of in order to use it, your again is to the sun. (It is onerous to burn your optic nerve that way) To make a pinhole viewer, simply take a medium sized, rectangular field and poke a small hole within the center of one of many brief sides. While standing together with your again to the solar, put the field over your head with the pinhole side dealing with the sun. You will note an inverted picture of the eclipse projected on to the opposite side of the box. (CAUTION: Do NOT look via the pinhole under any circumstances. It may possibly trigger rapid blindness)
One other safe method is to make use of two items of cardboard in the identical way that the field was used above. Merely take one piece of cardboard and poke a hole in it. Maintain the piece with the opening up to the solar and allow the light from the pinhole to challenge an image of the eclipse on to the opposite piece of cardboard. Once more, DO NOT look via the pinhole on the solar for ANY reason. Unprotected direct viewing of the photo voltaic eclipse may cause permanent blindness.
