This is a precut sheet of Helios Solar Film that is safe for direct solar viewing. It allows only .001% of sunlight to pass through it therefore has a neutral density of 5. It can be used under magnification and is therefore safe to use with any telescope, refractor, binoculars, view finders, spotting scopes or cameras. Use it for direct viewing or to make your own eclipse viewers and solar filters. It can be used to view the sun with the naked eye. Only one layer is needed and can be cut with scissors or a sharp razor. The material is .002 thick and is very sturdy and easy to work with. A natural yellow-orange image of the sun is viewed through the film. You will be able to see sun spots, surface granulation, eclipses, and planet transits when magnified. Before looking through the film at the sun be sure there are no pinholes, scratches, or tears.
