I have Virtual Moon and CDC. I also have Stellarium (another freeware program), its a bit simpler than CDC but I find it good to go back to when I get frustrated because CDC won't do what I want it to
.
In terms of star charts I have TUMOL (The ultimate messier observeres log). This is a .pdf file downloadable from seds.org I think. It has coordinates, pictures and a small chart for finding each of the objects.
Also in the beginners section of IIS there are links to free star charts. A guy named Taki has produced a mag 7 and mag 8 star atlases both downloadable in pdf. Last week I enlarged the mag 8 charts to A3 size to make them easier to read when observing.
cheers.
