1. Introduction

TWO HUNDRED YEARS AGO astronomers were mainly preoccupied with the globe on which they lived and the solar system of which it was a member. Consequently, only nineteen objects outside the solar system were known. Today, hundreds of thousands of objects have been discovered that lie beyond our solar system and are known collectively as deepsky objects. This appellation covers clusters of stars, nebulae and the galaxies. These distant worlds are the objects of study for the deepsky observer.

Astronomer and author Robert Burnham Jr. wrote:

"The amateur astronomer has access at all times to the original objects of his study; the masterpieces of the heavens belong to him as much as to the great observatories of the world. And there is no privilege like that of being allowed to stand in the presence of the original."

FOR THE BEGINNER, observing the deep sky requires time, patience and a willingness to learn. A small telescope will reveal hundreds of objects to the skilled observer, and many thousands are within reach of a modest telescope. Through practice and experience, anyone can master the art of deep-sky observing. There are a wealth of deep-sky objects awaiting your scrutiny.

Observational astronomy is to a great extent an aesthetic pursuit. Enjoy the view as you explore the night sky, but in doing so, do yourself one favour: don't rush. As you move from one target to the next, pause a while. Don't just look at the universe - see the universe. Hopefully this guide will point you in the right direction as you start your journey of discovery.

"The pleasures of amateur astronomy are deeply personal. The feeling of being alone in the universe on a starlit night, cruising on wings of polished glass, flitting in seconds from a point millions of kilometers away to one millions of parsecs distant ... is euphoric."
-- James Mullaney
