Hey all,
I have been a member for some time but this is the first time I have posted.
Not sure if its been posted before but Microsoft have a similar thing to google sky (the whole "atlas" is made up of very detailed photos of the sky). Its called World Wide Telescope and is fun to use with guided tours (great for beginners) with music added.
