The Explore Scientific A4 Visual Solar Filter Film allows you to safely observe the sun with binoculars or even take photos of it without risking your eyes or valuable equipment.
The A4 size foil can be cut to any size you like, or even! You can even cut out a pattern for a small telescope and a pair of sun-viewing glasses. The filter shows the Sun in a slightly warmer orange tone than the Baader filter for the same purpose. You can design your own solar filter for astronomical binoculars, giant binoculars (binoculars), spectra, telephoto lenses.
Use solar filter foil only in front of the telescope, it is forbidden to use it on the eyepieces because it burns out!
