In this textbook the author brings back some of the 'old' astronomy, but viewed through the imaginary lens of huge telescopes and orbiting observatories. He teaches us what we can see in the sky without any instrument at all - with the only pre-requisite of access to a dark sky. We learn about lunar / solar eclipses and how contemporary cultures and ancient ancestors around the world discovered the sky.
