No, I'm still awake!

However, still a little confused. Once I have my scope polar aligned, what can I move (which axis) to look at, for example, Jupiter or Saturn etc... And what is a polar scope? On my RA axis beam thingy, there is a cap on the end which I can take off...and it's possible to look through from one end to the other. Is that the Polar scope?
