Complete manual of amateur astronomy

This book is for a person with an advanced interest in the science of Astronomy with a knack for woodworking. I find the book to be a guide on how to do real science with you backyard telescope. There are enough double stars and other objects to make the book worth while from my front sidewalk. The more read the book the more I like it. The maps are easy to read. Oh yes, you can see many of these Messier objects with your ETX some with the naked eye at dark sites as many observers have noted in the user feedback section of this site. This is a good book for beginners and even long time amateur astronomers will find some of the information useful.

What are the tradeoffs? At the back of the book is an excellent index of lunar formations, giving each feature's exact position on the relevant drawing.
