Welcome Jack! Lot's of fun ahead for you! I have the same scope as you, so if you ever need any help with specifics, please ask! (I'm no seasoned pro, but have been looking at the night sky for a few years now!). If you have an android phone or tablet, download an App called Mobile Observatory...it has details of objects you can see (magnitude, size etc) and also detailed and accurate sky maps as well as live viewing. The book, Astronomy Australia, is also a great source of info and of course you can email the telescope shop. But mate, this forum is FULL of info from very experienced astronomers...ask away!
Saturn would be best at about 4:30 - 5:00 am; in fact, it is quite good at the moment and easy to spot right in the head of Scorpio (which is a good sight in itself!)
Enjoy your new toy and keep looking up!
