Sunspots : An hour before total solar eclipse on 21.08.2017...
This was taken on 21.8.2017 on a fine day at the football ground of Brigham Young University in Rexburg, Idaho, USA. This was the final testing of equipment and settings before the total solar eclipse. A Baader AstroSolar Safety Foil was put before the lens. This foil is CE-tested and reduces the intensity of sunlight by 99.999% (optical density 5.0).
