Best Observing Guide Book

I am looking for the best observing guide book. I have only seen a couple and I know there are many. A couple of years age at GCSP a gentleman had a book that listed objects and included pictures of it with a short description. I do not know the name of it. I am looking for something like that.

Vince,

There are lots of very focused books, but the best overall is The Night Sky Observer's Guide, in my opinion. It covers double stars and DSO's of all kinds.

It sort of depends on what aperture scope you are using and how dark your skies are. If your scope is at least 7-8"and you have or can get to fairly dark skies, I'd say yes NSOG.
Much smaller aperture, and more than 3/4 of the book will be useless.
