There're a few things to remember if you want to take the shots that I did.
1) Take it east, don't tense up, you're going to take a whole bunch of pictures.
2) Most of the good shots happen on the other side of the plane.
3) The second best picture happens just after you took a picture, and there's no time to take another one.
4) The absolutely best picture EVER will happen while you're scratching yourself somewhere.
BTW - You will need a real time weather program. I use OpusFSI, but Active Sky Next is pretty good too. I've used both of them. Use the free trial to decide which one you like best. Neither is perfect, Both are VERY good.
Enjoy
Oh, yeah. You want to know the secret?
