To clarify, letting the lens temperature stabilise is only needed if you manually focus one and leave it alone. If you are frequently checking focus it isn't necessary.
For focusing on stars, I find that hard too. If there is something far on the horizon with light maybe that could be used, as it would be close enough to infinity.
