First of all, I must say, astonishing job on this. I am heading to up Lake Tahoe on the 6th for a shot similar to this. May I ask how you did this shot? I've heard of people using two separate photos for the stars and ground lighting, but I would love to hear how you did it! Thanks!
No. It's all one shot. I experimented with night shots 5 different nights. You need the high ISO and experiment with time. Even at 30 seconds there will be a slight blur to the stars due to the earth's rotation.
