I just got the Staff of Magnus and it's pretty sweet so I'd like to be able to use it a lot. But I've barely found any soul gems to keep it enchanted with. --- http://i79.photobucket.com/albums/j145/Jvchequer/Trollface_HD.jpg
You should have a quest to investigate Azura's Shrine. Take that quest and do as you are told. When you have the Star, take it to the Mage and not Azura. I know this is counter intuitive, but the power of Necromancy is impressive and the Black Star can hold normal souls as well as human souls, making it a better choice.

You have to choose which one you want I'm new to the series; can you tell me how I get those and what they do?
I think you need to go to Azura's shrine and do her quest to get the gems. The Azura star and Black Soul gem are refillable soul gems that even can hold human souls. --- Adversity introduces a man to himself.
