Lukas's Star Chart records stellar observations on a grid; one chart also carries a drawing of a sheriff's badge.
Lukas uses a large sheet of paper covered with dots, grid lines, and small notes to record his observations. He has brought his board and paper to the cafeteria even when the sky was unsuitable for stargazing. His charts record sighting dates, locations, and intensities; one also contains a five-pointed drawing of a sheriff's badge.
