Review on 🔭 Enhance Your Celestial Viewing Experience with 10"x10" Solar Filter Sheet for Telescopes, Binoculars, and Cameras by Amy Cosme

Supplied between thick paper for easy trimming. The simple instruction label highlights eye safety and application issues. The inscription "silver sides facing the sun” could be in bold – for asymmetrical designs; (I got lucky with a 50/50 chance)! I cut 1" and 1/2" styrofoam rings, inserted filter material in between and glued them together for small telescopes, binoculars and cameras in preparation for the August 21, 2017 solar eclipse.
