The Society's usual high quality. More than 700 pages, with recent high quality color plates of constellations and objects, all keyed to descriptions like their birding books. Monthly and partial-sky star maps by Tirion, moon atlas, constellations in depth, etc. Covers every constellation in both Northern and Southern hemispheres. Waterproof cover, 4"x7.5", like new condition. I paid $19.00, yours for $10 plus shipping.
