For beginners to advanced amateurs, there is no other guide more comprehensive and better formatted than Ridpath & Tirion's Guide to Stars and Planets. For starters you can get a broad picture of the sky for any month at any location, thus avoiding the need for a planisphere. Once you've found your way from constellation to constellation, you're ready to harvest the best this book offers: There is a map of each constellation, showing the most interesting and accessible objects for viewing with naked eyes, binoculars or small telescopes. Accompanying each map are descriptions of these objects. I've tried many guides and plenty of astronomical software, but this is the guide that I always take with me and it's the first port of call for information during an observing session - there's none better. Collins, how about another print run of the superb book?
