The most expensive one! Charts out of books or magazines are usually
only schematic and the lines drawn in are approximate. I would get a decent
atlas such as Tirion's J2000 sky atlas or a copy of Nortons' Sky
Atlas which you can get over at the
Sky and Telescope page. They are
accurate and definitive. Aside from that, without knowing exactly which
charts are in question, it is hard for me to judge in the blind!
