I ordered a copy of Piotr Byrch's Great Atlas of the Sky today. The atlas is on sale for only $99 (originally $260) and may well be discontinued. Billed as the 'world's largest atlas of the entire sky', the Great Atlas is indeed massive. Comprised of 296 maps, each covering 15° x 10° of the sky. Each map is 24 x 17 inches. Over 2.4 million stars are plotted down to magnitude 12, along with over 70,000 galaxies, clusters, and nebulae. Coming from Poland, the atlas will take some two months to produce/ship. I'll provide a review when it finally arrives!
