Catherine Whitwell wrote an introduction to the night sky as a dialogue between a mother and daughter. It contains 23 engraved plates drawn by Whitwell herself, including four hand colored folding plates. One of the plates depicts the constellations of Corvus the Crow, Crater the Cup and Hydra the Water Snake. Another plate conveys a dramatic impression of the Full Moon at night, shown against a striking black background. This OER explores the role of Whitwell in astronomy education.
