Nebulae are the places where the stars are born. They can also be opaque clouds of dust that block our view of the stars beyond, starlight reflecting on cosmic dust clouds, or hot luminous expanding gases left over from a supernova explosion. Any description of this class of celestial object is... well... nebulous.

And yet this broad category contains the most fascinating and beautiful objects in the night sky. Some are easy to see, while others challenge the most experienced observers.

Nebulae and How to Observe Them presents an up-to-date detailed description and categorization of nebulae (part one); and then (part two) describes in practical terms how best to successfully observe and record them.

This book is a mine of information for all levels of amateur astronomy, from relative beginners to experienced observers. In one book, here is all you need to understand and observe those diverse and beautiful objects that fall under the heading of 'nebulae'.

Zusammenfassung

This Astronomers' Observing Guides are designed for practical amateur astronomers who not only want to observe, but want to know the details of exactly what they are looking at.

Nebulae are the places where the stars are born. For amateur astronomers, the many different kinds of nebulae vary from "easy" targets that can be seen with modest equipment under mediocre skies, to "challenging" objects that require experienced observers, large telescopes and excellent seeing.

The concept of the book - and of the series - is to present an up-to-date detailed description and categorisation (part one); and then (part two) to consider how best to successfully observe and record the large range of astronomical objects that fall under the general heading of "nebulae".

Nebulae and How to Observe Them is a mine of information for all levels of amateur observers, from the beginner to the experienced.
