Un Cielo tan Claro como el Zafiro

This is the inexpensive paperback edition of the book on the past, present and future of astronomy in the Philippines and other countries: investigating why Rizal did not construct an astronomical telescope when he had the know-how and the materials to do so. The title of this book, "A Sky as Clear as Sapphire" in English, comes from a phrase used by Rizal in the 60th chapter of his first novel, Noli Me Tangere. Many astro-photographs converted from full color to black-and-white and gray scale, surprisingly turned out extraordinarily beautiful.
