I'm sure I've posted this before. If you want to see the sky as it should look from where you live, and zoom in and out and change the time ahead or back minutes, hours, days, years, there is a free program that's REALLY cool. You can even add in satellites, asteroids, etc.... You can click on items and get info/details, etc.... It models the correct locations of the moons of planets (like Saturn and Jupiter) and even the Great Red Spot on Jupiter is in the correct location at any time.
Did I mention it's free?
I'm not affiliated, just an enthusiastic user. I've used this when using my scope to find hard to find objects, or when I can't get outside to just browse the sky.
Stellarium.
They've got it for Windows, OSX and Linux.
