Astronomy labs usually happen in the middle of the night on some rooftop on the outskirts of town, away from the pink undertones of city lights. Setting up shop in the middle of campus on a Wednesday afternoon, as students crisscross the library lawn, attracted a crowd. Groups of preschoolers stopped for an explanation, seasoned professors inquired about the lesson and every so often a student in the course, obligated to look and appreciate, would peer into a telescope.
Who knew there were so many types of welder's glass as well? No. 14 to look safely at the sun, in case you plan to try this one at home.
