You don't, of course, really have to do that. Just face in the direction you want, orient the wheel so that the "horizon" on the wheel represents the same direction you are facing, and remember that the other "horizon" on the wheel (the one straight up) represents the real horizon behind you.
I find those wheels very useful for the broad picture. Star maps are good if you have a telescope or binoculars, but remember that telescopes invert images in one way or another and you must compensate mentally for that inversion.How do you use a star/constellation wheel?you have to line up the date to the current time (assuming that you are talking aobut a planisphere) so tonight you'd like up september 5th to 9 pm for example. then you would hold the planisphere up to the sky so that the directions match up
if you lay the planisphere flat you will notice that the directions are backwards, holding it up will show the directions in the proper..umm.. directions.
the rest is just matching up the stars on the planisphere to the ones in the sky
