Thirty-Nine Easy Astronomy Experiments

These experiments have been designed to teach readers how to measure the angle and attitude of the sun and stars, measure the diameter of the sun and moon, determine time and location from the sky, make maps of the stars and constellations, classify stars by temperature, use refracting and reflecting telescopes, and photograph star tracks. The book also provides instructions for building an astrolabe, a sundial, a cross-staff, a spectroscope, a sky clock, and other simple instruments.
