Hi Daniel,
As the other guys have said, with the right charts and of course experience you'll be able to see a lot more than you have up to now.
Having said that, going to a darker sky helps greatly.
I'm the president of The Macarthur Astronomical Society, I would like to invite you to our observing night at The Oaks this Saturday night, you would be made most welcome.
The objects your scope will see from there will blow you away.
Let me know if you would like to come.
Cheers, John.
