Hi Rachel,
I only have a 5" telescope at the moment (in the process of upgrading to 10") and i can see Saturn fine, just a tad on the tiny side. Also I have had some decent views of Jupiter.
Just a recommendation that might make it easier for you to find things is a free downloadable program called Stellarium

. It's the one I use all the time to see what's in the sky and when. We still don't understand how to use degrees and angles to line things up

. I use the Southern Cross as my starting point and work from there

.
The people on this forum site, IIS are a great help also and be prepared for some early cold mornings
