I just received my hefty copy of this wonderful and encyclopedic work in today's mail. I can't remember the last time I was so completely satisfied and thrilled with a book purchase! If you are at all serious about amateur astronomy, this book is truly a "MUST OWN" item. When people told me it was "even better than Burnham's" classic work I thought they must be exaggerating. They weren't. It is better than Burnham's in all matters of practical significance to the amateur observer. It covers many more celestial objects and contains much detailed and useful information about each one. The layout and design of the pages are much superior to Burnham's as well, as are the ubiquitous maps, drawings and illustrations. Burnham's still has more "star lore" material, -- so you'll want to keep your old copies -- but all in all this is a much more usable and complete observer's guide. Truly this is a solid five star product! Congratulations to the authors on their incredible accomplishment!
