I don’t know much about shooting the sky (though I did recently just learn about night shots) but I took these a couple weekends ago in/near Alabama Hills, California. Shot using a Nikon D3S with a Nikkor 28-300 & a Nikkor 105 mm (the sunrise one.)
The most beautiful thing we can experience is the mysterious. It is the source of all true art and all science. He to whom this emotion is a stranger, who can no longer pause to wonder and stand rapt in awe, is as good as dead: his eyes are closed.
