Well, you don't need to go through all that trouble, its dark outside, just go out and look at the sky and see the stars, they will be there when the horizon becomes visible."
Doesn't that require an ability to confidently locate and 'lock on' to the chosen stars in a brightening and perhaps cloudy sky, with the constellations and their various pointers rapidly disappearing? Setting up the star finder isn't that onerous, especially when having regard for your second point, re LHA Aries.
