Vol. 19 of Otona no Kagaku ("Science for Adults") features the telescope of Galileo, and his views of astronomy in the 17th century. Includes a functional model (assembly required) of Galileo's telescope, plus an 82-page book on Galileo and astronomy, past and present. Very educational, and fun, too!
