I got a Suunto Tandem last week. It is very very handy for finding the az/el. The Tandem is kind of expensive, the cheapest I have found is around $170. If you have never seen or heard of one, I hadn't, I'm including a couple links. Hope this helps.

That's very much correct, yes. Happens to myself often enough. :)
Simply holding out your arm for pointing at the sky indeed gets you pretty
much nowhere, that's just a guess like any other.
Maybe I should have stated more clearly what my take at this is. If you
hold your hand flat out and in front of your eyes, and then turn it
straight up, you have an imaginary reference frame/angle of 90° that helps
you to figure where the "half", 45° is in this frame, and then hold your
hand at that angle. Now simply look up (sideways) along your hand and there
you are (and maybe you get this "boy, is that high up" feeling :). Again,
this is not very accurate, just a small trick. Works equally well with
holding your forearm in front of your eyes instead of your hand, and your
arm also gives you a longer line to aim along.
And maybe I should have added that all of this surely needs practice and
experience. As usual, you're getting better over time.
