Telescopic View of the Full Moon.

This chart, titled Telescopic View of the Full Moon, is featured in Smith's Illustrated Astronomy, a groundbreaking educational work created for use in public and common schools throughout the United States. Authored by Asa Smith, Principal of Public School No. 12 in New York City, the book sought to simplify the complex principles of physical astronomy. Smith emphasized clarity and comprehension, stating his objective was “to present all distinguishing principles in physical Astronomy with as few words as possible; but with such ocular demonstrations, by way of diagrams and maps, as shall make the subject easily understood.”

The chart vividly illustrates the surface of the full moon as seen through a telescope, highlighting its craters, plains, and mountains. Designed for accessibility and engagement, this depiction exemplifies Smith's dedication to making astronomy approachable for young learners, bridging scientific inquiry with clear visual representation.
