Students from Novosibirsk developed a portable device for observing total sun eclipse, which will happen on August 1. The device consists of two lenses with a special light filter for the image to be sharp and have high quality.
Simple paper spectacles with dark lenses allow watching only how dark Moon covers yellow Sun, and special glass of new development reveals all bright colours of the event. Researchers plan to make about 8 thousands of such devices, which can be bought in Novosibirsk before the eclipse.
