G,day Chris,
Congratulations on your purchase the universe awaits
It sounds like you have the basics to get you started. The next piece of hard ware you should get as others have mentioned is a collomation/ cheshire eyepiece. But as the focal length of your 'scope is 1200mm (f8 focal ratio) collomation isn't too traumatic or stressfull
Another very importanrt piece of kit is the Guide book and/or Star atlas. These will help you find your way around the sky and after a bit of practice finding deep sky objects and planets wont be a problem. Don't forget the Astronomy mags they always have articles about what is visable in the night sky complete with maps and diagrams. the best mags are the two Aussie one's Sky and Space and Australian Sky and Telescope as they concentrate on our great southern hemisphere.
Enjoy our great hobby
