Thousand Oaks Optical BP-6X6 6 inchx6 inch Solar Filter Sheet for Telescopes, Binoculars and Cameras

Black polymer is the most common filtering material for observing sunspots and granulation, through telescopes and binoculars. Make a filter on your own for any telescope / binoculars / camera, and for a fraction of what factory made filters cost. The sun will appear in a natural orange color when viewed through your telescope using this filter. WARNING: ALWAYS MAKE SURE THE FILTER IS WELL ATTACHED TO THE TELESCOPE/BINOCULARS, USING STICKY TAPE, TO KEEP IT FROM FALLING WHILE OBSERVING! International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.
