About the Publisher

Introduction

The Moon is our celestial companion; a source of light; a comfort to many; an icon. It is older than history, and has accompanied our species, hanging silently above, since we emerged from the oceans, where its presence is still felt today. It is the master of the tides – perhaps the key to life itself – and it has inspired stories, poetry, music, and visual artworks of great beauty.

Today we live in an age where the entirety of the Moon’s surface has been mapped in astonishing detail from orbit, and human beings have left imprints in its soil. It may seem like there is nothing left to discover there, and yet the Moon keeps calling to us – a hypnotic siren song, urging us to revisit it. Our longing to explore has never been stronger.

A modern amateur telescope – even an inexpensive one – can take you on your own personal voyage to the Moon, where you’ll find a timeless landscape whose deep shadows and brilliant highlights are ever changing. Its serene character betrays its true nature as a world of incredible extremes. You can spend a lifetime enjoying these views, and placing yourself there in your mind, just as every great lunar observer before you has, since the invention of the telescope four centuries ago.

It is my hope that this guide will get you better acquainted with the Moon, enabling you to begin making your own observations, and producing your own images. There is no better destination for new space travellers, and the advice ahead will help you take one small step to reach it. Good luck!

Dedicated to Patrick Moore, my mentor and friend. I miss you.
