I have that Google Sky Map program on my Rezound phone. Turn on GPS and it tells you what you are looking at. I kind of know where Polaris is after a few shots.
The only bad thing about those shots is a 30 minute exposure actually takes an hour for it to process all the noise out. Dark frame subtraction.
