This is the second book in the Stephen James O'Meara trilogy, the first being "The Messier Objects". Each book is thicker and heavier (by quite a margin!) than the previous book.
The Caldwell Objects is a catalogue of the 109 deep-sky objects first listed by our very own Patrick Caldwell-Moore in the December 1995 issue of Sky & Telescope magazine (U.S.A.).
As with the previous Messier Objects book, each Caldwell object is accompanied by a nice B&W image, a sketch of O'Meara's impression of the object through a small refractor, and some excellent prose which adds greatly to the overall quality of the book.
A very big improvement over the Messier Objects book is the inclusion of an Index!
Very informative and a must-have companion to his earlier Messier Objects. I refer to both books on at least a weekly basis.
