Viewing the Sky,This book is about nebulae, those clouds of gas and dust that are the beginnings and endings in the lifetime of stars. We will get into much more detail about that later. Right now, I would like to introduce myself and discuss the reasons for this book and some rudimentary information about the equipment you will need to observe the Universe.

Using a Computer,There are many things that a good computer can do for you in the area of observing the deep sky. I am not going to spend time going over types of computers and their components. Any well-made modern computer will do. A faster processor, more memory and a larger hard drive are nice, but not essential to a computer that will be useful for astronomy.

A Fun Night Under the Stars,In this chapter I will explore what it takes to create a fun night out observing for me. I hope that you will see some patterns that you can add to your observing sessions.

Introduction to Observations, within them. I just want you to know that this is not a complete set of information on all the nebulae in the sky. The number of pages assigned to this task by my editor would not allow that. Besides, I would not want to try and write that book.
