Hi Matt
Congrats on your purchase, you'll be blown away by what is up there.
All fantastic suggestions by the other members and a couple of my personal favourites M45 and Tarantula Nebula (NGC2070) are amazing objects and you'll find them pretty easily.
I see you are at Shellharbour, views are clearer up the hill at Robbo

At least when we don't have the sea mist blocking us out.
Enjoy!
Wayne
