Steve the 2006 Astronomy is an Ephemeris(?) for the position of the planets and moon for the 12 months along with Jupiter and Saturn moon positions, rise and set times for all planets, major minor
planet positions, monthly important planetary, cometary, asteroidal and occulation information, Blah Blah Blah. I couldn't do without it. I have the Southern Star guide as well and the two book go everywhere with me (along with the cambridge star atlas)
